Abstract

A method of managing bets is provided. The method includes receiving win bets and group bets. Each win bet includes a bet that a participant selected from a set of participants in an event will win the event. Each group bet includes a bet that one of a subset of the set of participants will win the event. Results of the event identifying a winning participant from the set of participants are received. An amount of a win bet payout for at least a portion of the win bets that comprise a bet on the winning participant is determined. An amount of a group bet payout for at least one of the group bets is also determined. In this manner, a bettor may bet on all participants in an event other than a particular participant, such as the favorite participant, and thus effectively bet against the particular participant.

Description

[0001] Wagering on sporting events, such as horse races, for example, is a large and growing industry in many parts of the world. Various types of betting products or systems are available for various types of sporting events For example, typical horse racing bets allow bettors to bet on a single horse or on several horses in a particular race or series of races. For instance, a bettor can bet on a particular horse to finish first (win), finish in the top two (place), or finish in the top three (show). A bettor may also make various combination bets with multiple horses, such as an exacta bet (covering the top two horses in order) or a trifecta bet (covering the top three horses in order). In addition, a bettor may bet on a series of races, such as the daily double (winners of two consecutive races), the pick-three (winners of three consecutive races), and the pick-six (winners of six consecutive races), for example.

[0002] In a pari-mutuel betting system, all bets regarding a particular event are aggregated, a commission (or “take-out”) is taken by the track, and the remainder is distributed among the winning bettors. For example, pari-mutuel betting systems are commonly used in North America (and other various places throughout the world) for betting on horse races.

[0003] According to one embodiment, a method of managing bets is provided. The method includes receiving one or more win bets and one or more group bets. Each win bet includes a bet that a participant selected from a set of participants in an event will win the event. Each group bet includes a bet that one of a subset of the set of participants will win the event, wherein the subset includes a plurality of the set of participants. Results of the event identifying a winning participant from the set of participants are received. An amount of a win bet payout for at least a portion of the win bets that comprise a bet on the winning participant is determined. An amount of a group bet payout for at least one of the group bets is also determined.

[0004] According to another embodiment, a system for managing bets is provided. The system includes a memory coupled to a processor. The memory is operable to store one or more win bets and one or more group bets. Each win bet includes a bet that a participant selected from a set of participants in an event will win the event. Each group bet includes a bet that one of a subset of the set of participants will win the event, wherein the subset includes a plurality of the set of participants. The memory is also operable to store results of the event identifying a winning participant from the set of participants. The processor is operable to determine an amount of a win bet payout for at least a portion of the win bets that comprise a bet on the winning participant, and also to determine an amount of a group bet payout for at least one of the group bets.

[0005] Various embodiments of the present invention may benefit from numerous advantages. It should be noted that one or more embodiments may benefit from some, none, or all of the advantages discussed below.

[0006] One advantage of the invention is that in an event which includes a set of participants, a bettor may bet on a subset of the set of participants, and win the bet if any of the subset of participants wins the event. Thus, for example, a bettor who believes that a particular participant in an event will not win the event, but is unsure of which other participant to bet on, may purchase a group bet which includes a group of participants which excludes the particular participant. For example, a bettor who believes that the favorite in a horse race will not win the race, but is unsure on which other horse to bet, may purchase a group bet which includes every horse in the field except for the favorite.

[0007] In this manner, a bettor may bet on all horses other than the favorite (or another particular horse), thus effectively betting against the favorite, without having to place individual bets on each of the non-favorite horses. In some situations, a bettor may make such a group bet on an event when he or she otherwise would not have made a bet on the event, since the bettor need not place individual bets on each of the non-favorite horses. This may increase the total pool of wagers on the event, which may increase profits at least for the one or more entities that collect a percentage of the take-out on such wagers.

[0008] Another advantage of the invention is that such group bets may be provided in a pari-mutuel betting system in which all bets regarding a particular event are pooled.

[0009] Other advantages will be readily apparent to one having ordinary skill in the art from the following figures, descriptions, and claims.

[0010] For a more complete understanding of the present invention and for further features and advantages, reference is now made to the following description, taken in conjunction with the accompanying drawings, in which:

[0016]FIG. 5 is a flowchart illustrating an example method of receiving, managing, and paying win bets and group bets in accordance with an embodiment of the present invention;

[0017]FIG. 6 is a flowchart illustrating an example method of determining various odds, payouts and/or profits for win bets in accordance with an embodiment of the present invention; and

[0018]FIG. 7 is a flowchart illustrating an example method of determining various odds, payouts and/or profits for group bets in accordance with an embodiment of the present invention.

[0019]FIG. 1 illustrates an example system **10** for receiving and managing bets **12** in accordance with an embodiment of the present invention. System **10** includes one or more betting system interfaces **14** and a betting system platform **16** coupled by one or more communications networks **18**. In general, one or more clients **20** may receive betting information (such as event times, betting rules, betting options and odds, for example) and/or place bets **12** via betting system interfaces **14**. Betting system interfaces **14** communicate such bets **12** received from clients **20** to betting system platform **16**. Betting system platform **16** stores the received bets **12**, determines appropriate odds and payouts, and communicates such odds and payouts to one or more of the betting system interfaces **14**.

[0020] System **10** permits clients **20** to place at least both win bets (or straight wagers) **22**, as well as group bets **24** on a betting event having a set of event participants, such as a horse race, dog race, auto race, or golf tournament, for example. A win bet (or straight wager) **22** is a bet that a particular participant will win the event. For example, in a horse race, an example of a win bet **22** is a bet that Horse #**3** will win the race. A group bet **24**, on the other hand, is a bet that one of a group, or subset, of the set of participants will win the event. In some situations, the subset or group may include all of the participants in an event except for a single participant. In such situations, the group may include all of the participants in an event except for the “favorite,” or in other words, the participant having (or predicted to have) the best chance of winning the event. For example, in a 14-horse race in which Horse #**3** is the favorite, an example group bet **24** is a bet that any of the horses except for Horse #**3** will win the race.

[0021] By placing a group bet **24**, a client **20** may bet on all participants other than the favorite (or another particular participant), thus effectively betting against the favorite, without having to place individual bets on each of the non-favorite participants. Thus, for example, a bettor who believes that the favorite horse in a horse race a will not win the race, but is unsure on which other horse to bet, may purchase a group bet **24** which includes all horses except the favorite.

[0022] In some embodiments, more than one different group bet **24** may be available to clients **20**. For example, for a particular ten-horse race, a first group bet **24** may be available which covers Horses #**2**-#**10**, thus effectively providing a bet against Horse #**1**; a second group bet **24** may be available which covers Horses #**1** and #**3**-#**10**, thus effectively providing a bet against Horse #**2**; and a third group bet **24** may be available which covers Horses #**1**-#**4** and #**6**-#**10**, thus effectively providing a bet against Horse #**5**.

[0023] In alternative embodiments, the group of participants covered by a particular group bet **24** may exclude two, three, or any other number of participants in the event. For example, for the ten-horse race discussed above, a group bet **24** may be available which covers Horses #**3**-#**4** and #**6**-#**10**, thus effectively providing a bet against Horses #**1**, #**2** and #**5**. The number of participants for which a particular group bet **24** may cover may be related to the number of participants in the event. For example, in one embodiment, a group bet **24** in a six-horse race may cover all but one horse (such as the favorite horse), a group bet **24** in a eight-horse race may cover all but two horses (such as the top two favorites), and a group bet **24** in a race of ten or more horses may cover all but three horses (such as the top three favorites).

[0024] In some embodiments, system **10** is a pari-mutuel betting system in which all bets **12** (or at least a relevant group of bets **12**) regarding a particular event are pooled, a commission (or “take-out”) is taken by the track or other wagering provider, and the remainder is distributed among the winning bettors. In other embodiments, system **10** may be another type of betting system, such as a betting system in which clients **20** take positions against a bookmaker, for example.

[0025] Group bets **24** may be incorporated into an existing pari-mutuel pool in the following manner. Suppose, for example, a group bet **24** which covers all participants in an event except for the favorite participant. At the close of betting on a particular event, the amount of each individual group bet **24** (less the take-out rate) is divided and allocated among all participants covered by the group bet **24** such that the potential payout (in other words, the payout if the group bet **24** wins) for the group bet **24** is related to the odds on the favorite participant. Generally, the lower the odds on the favorite participant (in other words, the more that has been bet on the favorite), the greater the potential payout for the group bet **24**. Thus, a group bet **24** in a race in which the favorite participant has 3-5 odds pays more than a similar group bet **24** in a race in which the favorite participant has 2-1 odds. In one embodiment, the payout for the group bet **24** is equal to the inverse of the odds on the favorite participant. Thus, in this embodiment, if the favorite participant has 2-5 odds, the group bet **24** will payout at a 5-2 rate.

[0026] Betting system interfaces **14** may include any suitable interface between a client **20** and betting system platform **16**. For example, as shown in FIG. 1, betting system interfaces **14** may include physical interfaces, such as track interfaces **26** and/or off-track interfaces **28**. Track interfaces **26** are generally located at a track, while off-track interfaces **28** are generally located at an off-track-betting (OTB) establishment, such as an OTB parlor. Track interfaces **26** and off-track interfaces **28** may include tellers **30**, which may receive bets **12** from and distribute payouts to clients **20**, and/or monitors **32**, which may be viewed by clients **20** to monitor betting information such as the event time, the current odds, and the projected or actual payouts for various bets **12**, for example. In some situations, such information may be updated substantially in real time or at preset intervals (such as every 30 seconds, for example) as new bets **12** are placed and/or as information regarding the event changes, for example. Monitors **32** may include, for example, tote-boards or closed-circuit televisions located at a track or OTB establishment.

[0027] Track interfaces **26** and/or off-track interfaces **28** may also include one or more self-service betting machines **33**. In some embodiment, self-service betting machines **33** allow clients **20** to insert payment into the machine (such as cash or by using a voucher or a credit or debit card), place one or more win bets **22** and/or group bets **24**, and receive a printout (such as a ticket, for example) indicating the bet or bets placed. Printouts for winning bets may be inserted into the self-service betting machine, such as to receive a payment voucher (which may be used to receive a payout from a teller **30**) or to place additional bets **12**. In other embodiments, self-service betting machines **33** allow clients **20** to use a credit or debit card to place bets **12**. The credit or debit card may have an associated account, which may be a betting account provided and/or managed by a betting account provider. In some embodiments, after the betting event is completed, a client **20** may insert or swipe his or her credit or debit card in the self-service betting machines **33** in order to update the balance on the card. Self-service betting machines **33** may also allow the client **20** to print out payment vouchers which may be presented to a teller **30** in order to receive payments.

[0028] As shown in FIG. 1, betting system interfaces **14** may also include various non-physical interfaces, such as one or more telephone operators **34** and one or more websites **36**. Clients **20** may access or communicate with such non-physical interfaces via one or more communications networks **44**. Communications networks **44** may include one or more servers, routers, switches, repeaters, backbones, links and/or any other appropriate type of communication devices coupled by links such as wire line, optical, wireless, or other appropriate links. In general, communication network **28** may include any interconnection found on any communication network, such as a telephone network, a local area network (LAN), metropolitan area network (MAN), wide area network (WAN), the Internet, portions of the Internet, or any other data exchange system. To access betting system interface **14** using communication networks **44**, clients **20** may use a computer, a personal digital assistant (pda), a cell-phone, a remote paging device, an electronic mail communication device, a handheld betting device, or any other suitable mobile device. In certain embodiments, clients **20** may receive any suitable information, such as betting information, from betting system platform **16** via mobile devices using, for example, communication networks **44** and betting system interfaces **14**.

[0029] Telephone operators **34** may communicate betting information (such as event times, betting rules, betting options and odds, for example) to, and take bets **12** from, clients **20**. Similarly, websites **36** may communicate betting information to clients **20** and allow clients **20** to place bets **12**. One or more of such websites **36** may be hosted by one or more servers associated with system **10**, which server or servers may also host betting system platform **16** in some embodiments. In some embodiments, betting information available to clients **20** via websites **36** may be updated substantially in real time or at preset intervals (such as every 30 seconds, for example) as new bets **12** are placed and/or as information regarding the event changes, for example.

[0030] In some embodiments, one or more websites **36** may be provided by, or associated with, an Internet betting provider **46**, for example. Internet betting provider **46** may provide Internet account wagering by providing online betting accounts to one or more clients **20**. Using an online betting account, a client **20** may interface with one or more websites **36** associated with the Internet betting provider **46** in order to fund the account, view betting information regarding betting events, and place bets (such as win bets **22** and/or group bets **24**). Such online betting accounts may include one or more various types of accounts, such as deposit accounts, credit accounts, stop-loss accounts, and hybrid accounts, for example.

[0031] Some or all of the betting system interfaces **14** of system **10** may be operable to offer or receive both win bets **22** and group bets **24**. However, in some embodiments, one or more betting system interfaces **14** may only offer or receive either win bets **22** or group bets **24**. For example, in a particular embodiment, a website **36** may allow clients **20** to place both win bets **22** and group bets **24**, while a particular OTB parlor **28** may only allow clients **20** to place win bets **22**.

[0032] As discussed above, betting system platform **16** is operable to receive bets **12** (including both win bets **22** and group bets **24**) from betting system interfaces **14**, store the received bets **12**, determine appropriate odds and payouts, and communicate such odds and payouts to one or more of the betting system interfaces **14**, which may then display such odds and/or payouts to clients **20**. As shown in FIG. 1, betting system platform **16** includes a processor **38** coupled to a memory **40**. Processor **38** is generally operable to execute various algorithms or calculations to determine current odds data **50**, such as current pool data **52**, current odds data **54** and/or potential payout data **56**, shown in FIGS. 2A, 2B and **2**C, which are discussed below in greater detail.

[0033] As discussed above, betting system platform **16** comprises processor **38** and memory **40**. Processor **38** may comprise any suitable processor that executes a betting system software application **42** or other computer instructions, such as a central processing unit (CPU) or other microprocessor, and may include any suitable number of processors working together. Memory **40** may comprise one or more memory devices suitable to facilitate execution of the computer instructions, such as one or more random access memories (RAMs), read-only memories (ROMs), dynamic random access memories (DRAMs), fast cycle RAMs (FCRAMs), static RAM (SRAMs), field-programmable gate arrays (FPGAs), erasable programmable read-only memories (EPROMs), electrically erasable programmable read-only memories (EEPROMs), microcontrollers, or microprocessors.

[0034] Memory **40** is generally operable to store various information that may be used by processor **38** in determining odds and/or payouts. For example, memory **40** may comprise any suitable number of databases, which may be co-located or physically and/or geographically distributed. In the example shown in FIG. 1, memory **40** may store any or all of the following: betting system software application **42**, current odds data **50**, one or more event parameters **58**, one or more bet parameters **60**, one or more calculation rules **62**, one or more event results **64**, and one or more bet results **66**. Event parameters **58** may comprise various parameters of one or more betting events, such as, for example, the type of event, the time, date and location of the event and/or the number (or in some cases, the name) of each of the participants in the event. Bet parameters **60** may comprise various parameters of one or more received bets **12**, such as the identity of the client **20** who placed the bet **12**, the manner in which the bet **12** was placed (such as via telephone, the Internet, or in person at a track or OTB establishment, for example), the type of bet **12** (such as whether the bet **12** is a win bet **22** or a group bet **24**, for example), the commission rate on the bet **12**, the participant or participants covered by the bet **12** and/or the amount of the bet **12**, for example. Calculation rules **62** may comprise various equations or other algorithms to be used by processor **38** in determining various current odds data **50**. Examples of such equations are illustrated and discussed below with reference to FIGS. 3A and 3B. Event results **64** may comprise various data regarding the results of one or more betting events, such as the final position of each participant in an event, whether there was a tie for any position and/or whether any participants did not finish the event, for example. Bet results **66** may comprise various data regarding the results of various bets **12**, such as the identity of the client **20** who placed the bet **12**, whether the bet **12** was a winning bet, the determined payout for the bet **12** and/or whether the payout was distributed to the client **20**, for example.

[0035] As discussed above, one or more communications networks **18** couple and facilitate wireless or wireline communication between one or more betting system interfaces **14** and betting system platform **16**. Each communication network **18** may include one or more servers, routers, switches, repeaters, backbones, links and/or any other appropriate type of communication devices coupled by links such as wire line, optical, wireless, or other appropriate links. In general, each communication network **18** may include any interconnection found on any communication network, such as a local area network (LAN), metropolitan area network (MAN), wide area network (WAN), the Internet, portions of the Internet, or any other data exchange system.

[0036] As discussed above, processor **38** is operable to execute betting system software application **42** to determine current odds data **50**, such as current pool data **52**, current odds data **54** and/or potential payout data **56**, shown in FIGS. 2A, 2B and **2**C. Processor **38** may determine such current odds data **50** based at least on data received from memory **40** and/or one or more betting system interfaces **14**. In addition, processor **38** may update such current odds data **50** based on new information being received by betting system platform **16**. In some embodiments, processor **38** may update current odds data **50** in real time, substantially in real time, or at preset intervals (such as every 30 seconds, for example).

[0037] As shown in FIG. 1, current odds data **50** may be communicated to one or more betting system interfaces **14** via communications network **18**, as indicated by arrow **70**. Current odds data **50** may then be made available to clients **20**, such as via tote boards or monitors **32** located at a track or OTB establishment, for example, or on an appropriate website **36** that may be accessed by clients **20**, for example. In this manner, clients **20** may have access to real-time or substantially real-time current odds data **50** regarding various betting events.

[0038]FIGS. 2A, 2B and **2**C illustrate example types of current odds data **50** for an example horse race in which Horse #**4** is the favorite and a group bet **24** is offered which covers Horse #**1**, Horse #**2**, Horse #**3** and Horse #**5** (all horses except Horse #**4**). FIG. 2A illustrates current pool data **52** reflecting the current total amount, or the current stake, of win bets **22** on each horse and the current total amount, or the current stake, of group bets **24**. Thus, FIG. 2A illustrates the total current win bet stake on each horse, as well as the total current group bet stake on the group bet **24**.

[0039]FIG. 2B illustrates current odds data **54** reflecting the current odds on the win bet **22** for each horse and current odds on the group bet **24**, both without and with take-out at a 15% rate. FIG. 2C illustrates potential payout data **56** reflecting the potential payout for each win bet **22** for each horse and the potential payout for the group bet **24** if betting were closed at that point (in other words, if no additional bets were accepted for that betting event). FIG. 2C illustrates the potential payout for each bet both without and take-out at a 15% rate.

[0040] As discussed above, processor **38** may calculate various current odds data **50** using various algorithms or equations. FIGS. 3A and 3B illustrate examples of such algorithms or equations in accordance with one embodiment of the present invention. In particular, FIGS. 3A and 3B illustrates various equations for calculating the current potential payout for each bet **12**, including both win bets **22** and group bets **24**, associated with a particular betting event. The equations shown in FIGS. 3A and 3B are similar; however, the equations shown in FIGS. 3A account for take-out, while the equations shown in FIGS. 3A do not. The equations shown in FIGS. 3A and 3B are best understood when viewed in conjunction with FIGS. 4A-4F, as discussed below.

[0041] As discussed above, FIG. 3A illustrates various equations for calculating the current potential payout for both win bets **22** and group bets **24**, accounting for take-out (commission). In particular, FIG. 3A illustrates an after-commission (AC) group bet pool equation **100**; a participant's AC win bet stake equation **102**; a total AC win bet stake equation **104**; an AC group-participant win bet pool equation **106**; a total AC pool on all participants equation **108**; an AC group bet pool allocation equation **110**; a participant's total AC stake equation **112**; a pair of alternative total AC group bet payout equations, **114**A and **114**B; a total AC group bet profit equation **116**; a pair of alternative AC payout per group bet unit currency equations, **118**A and **118**B; a pair of alternative total AC win bet payout equations, **120**A and **120**B; a total AC win bet profit equation **122**; and a pair of alternative AC payout per win bet unit currency equations, **124**A and **124**B.

[0042] The AC group bet pool equation **100** may be used to determine the after-commission group bet pool, which is equal to the before-commission (BC) group bet pool minus the take-out. In some embodiments, the take-out is a percentage of each bet **12**, and the total take-out for an event is thus that percentage of the total pool. For example, if the take-out rate is 15%, the take-out on each win bet **22** or group bet **24** is equal to 15% of such win bet **22** or group bet **24**, and the total take-out for the event is 15% of the total pool for the event. However, it should be understood that in alternative embodiments, the take-out (commission) may be otherwise calculated. For example, a separate take-out rate may be charged for win bets **22** and group bets **24**.

[0043] The participant's AC win bet stake equation **102** may be used to determine the total AC win bet stake on each participant in the event. According to equation **102**, the AC win bet stake on each participant is equal to the BC win bet stake on that participant minus the take-out.

[0044] The total AC win bet stake equation **104** may be used to determine the total AC win bet stake on all participants, which equals the sum of the AC win bet stake on each participant (as determined using equation **102**).

[0045] The AC group-participant win bet pool equation **106** may be used to determine the total AC stake of win bets **22** on each participant in the group, or subset, of participants covered by the group bet **24**. The participants in the group of participants covered by the group bet **24** may be referred to as the “grouped participants.” For example, in a 5 horse race in which Horse #**4** is the favorite and a group bet covers Horses #**1**, **2**, **3** and **5**, the group-participant win bet pool equation **106** may be used to determine the total AC stake of win bets **22** placed on Horses #**1**, **2**, **3** and **5**.

[0046] The total AC pool on all participants equation **108** may be used to determine the total AC pool, including the total pool of back bets **22** and group bets **24**. According to equation **108**, the total AC pool is the sum of the total AC win bet stake (as determined by equation **104**) and the AC group bet pool (as determined by equation **100**).

[0047] The AC group bet pool allocation equation **110** may be used to determine the allocation of the AC group bet pool among each of the grouped participants. According to equation **110**, the AC group bet pool (as determined using equation **100**) is allocated among the grouped participants in direct proportion to the stake of AC win bets **22** placed on each of the grouped participants (as determined using equation **102**).

[0048] The participant's total AC stake equation **112** may be used to determine the total AC stake on each participant in an event. According to equation **112**, the total AC stake on each participant is the sum of the AC win bet stake on that participant (as determined using equation **102**) and the portion of the AC group bet pool allocated to that participant (as determined using equation **110**).

[0049] Each of the alternative total AC group bet payout equations, **114**A and **114**B, may be used to determine the potential total AC payout for the AC group bet pool if each participant were to win the event. According to equation **114**A, the total AC group bet payout for each particular participant is based on the total AC stake on all participants except for the particular participant (as determined using equation **112**), the total AC stake on the particular participant (as determined using equation **112**), and the portion of the AC group bet pool allocated to the particular participant (as determined using equation **110**). According to equation **114**B, the total AC group bet payout for each particular participant is based on the total AC pool on all participants (as determined using equation **108**), the portion of the AC group bet pool allocated to the particular participant (as determined using equation **110**), and the total AC stake on the particular participant (as determined using equation **112**).

[0050] It should be understood that using the equations shown in FIG. 3A, the AC group bet payout will be the same if any of the subset of participants covered by the group bet **24** wins the event. Thus, by placing a group bet **24**, a bettor may effectively bet against a particular participant (the participant excluded from the subset of participants covered by the group bet **24**), and be assured of a particular payout if any of the participants covered by the group bet **24** wins the event.

[0051] The total AC group bet profit equation **116** may be used to determine the potential total AC profit on the AC group bet pool if each participant were to win the event. According to equation **116**, the total AC group bet profit is equal to the total AC group bet payout (as determined using equation **114**) minus the total BC group bet pool.

[0052] Each of the alternative AC payout per group bet unit currency equations, **11** **8**A and **11** **8**B, may be used to determine the potential AC payout per unit of currency (such as one dollar, one pound, or other unit of currency) wagered on group bet **24** if the group bet **24** were to win. For example, equations **118**A and/or **118**B may be used to determine the potential AC payout per dollar wagered on group bet **24**.

[0053] According to equation **118**A, the potential AC payout per unit currency for each group bet **24** is based on the BC group bet pool and the total AC group bet payout (as determined using equation **114**). According to equation **118**B, the potential AC payout per unit currency for each group bet **24** is based on the total AC pool on all participants (as determined using equation **108**), the total AC stake on a particular participant (as determined using equation **112**), the portion of the AC group bet pool allocated to the particular participant (as determined using equation **110**), and the AC group bet pool (as determined using equation **100**).

[0054] Each of the alternative total AC win bet payout equations **120** may be used to determine the potential total AC payout for the total AC win bet stake on each particular participant if that participant were to win the event. According to equation **120**A, the total AC win bet payout for each particular participant is based on the total AC stake on all participants except for the particular participant (as determined using equation **112**), the total AC stake on the particular participant (as determined using equation **112**), and the AC win bet stake on the particular participant (as determined using equation **102**). According to equation **120**B, the total AC win bet payout for each particular participant is based on the total AC pool on all participants (as determined using equation **108**), the AC win bet stake on the particular participant (as determined using equation **102**), and the total AC stake on the particular participant (as determined using equation **112**).

[0055] The total AC win bet profit equation **122** may be used to determine the potential total AC profit on the total win bet stake on each particular participant if that participant were to win the event. According to equation **122**, the potential AC profit on the total win bet stake on each participant is equal to the potential total AC win bet payout for that participant (as determined using equation **120**) minus the total BC win bet stake on that participant.

[0056] Each of the alternative AC payout per win bet unit currency equations **124** may be used to determine the potential AC payout per unit of currency (such as one dollar, one pound, or other unit of currency) wagered on each win bet **22** if that win bet **22** were to win. For example, equations **124**A and/or **124**B may be used to determine the potential payout per dollar wagered on each winning win bet **22**.

[0057] According to equation **124**A, the potential AC payout per unit currency for each win bet **22** on a particular participant is based on the total BC win bet stake for that participant and the potential AC total win bet payout for that participant (as determined using equation **120**). According to equation **124**B, the potential AC payout per unit currency for each win bet **22** on a particular participant is based on the total AC pool on all participants (as determined using equation **108**) and the total BC stake on the particular participant (as determined using equation **138**, shown in FIG. 3B).

[0058] As discussed above, FIG. 3B illustrates various equations for calculating the current potential payout for both win bets **22** and group bets **24**, without accounting for take-out (commission). In particular, equations FIG. 3B illustrates a total BC win bet stake equation **130**; a BC group-participant win bet pool equation **132**; a total BC pool on all participants **134**; a group bet pool allocation equation **136**; a participant's total stake equation **138**; a pair of alternative total group bet payout equations, **140**A and **140**B; a total group bet profit equation **142**; a pair of alternative payout per group bet unit currency equations, **144**A and **144**B; a pair of alternative total win bet payout equations, **146**A and **146**B; a total win bet profit equation **148**; and a pair of alternative payout per win bet unit currency equations, **150**A and **150**B. Equations **130** through **150** are similar to equations **104** through **124**, respectively, shown in FIG. 3A, but without accounting for take-out.

[0059]FIGS. 4A through 4F may be used to illustrate the calculation of payouts and profits for win bets **22** and group bets **24** for various results of an example horse race using the example equations shown in FIGS. 3A and 3B in accordance with an embodiment of the present invention. In the example shown in FIGS. 4A through 4F, the horse race is a five-horse race, Horse #**4** is the favorite, and a group bet **24** is provided which covers Horses #**1**, **2**, **3** and **5** (all horses except Horse #**4**). It should be understood that the payouts and profits calculated as described above may comprises potential payouts and profits, which may be calculated and/or updated dynamically prior to the race, or actual payouts and profits, which may be calculated after betting on the race has been closed, or after the race has been run and/or declared “official.”

[0060] Each of FIGS. 4A through 4E illustrates the calculation of the potential payouts and profits for win bets and group bets if a particular horse were to win the race. In particular, FIG. 4A illustrates the calculation of the potential payouts and profits if Horse #**1** were to win; FIG. 4B illustrates the calculation of the potential payouts and profits if Horse #**2** were to win; FIG. 4C illustrates the calculation of the potential payouts and profits if Horse #**3** were to win; FIG. 4D illustrates the calculation of the potential payouts and profits if Horse #**4** were to win; and FIG. 4E illustrates the calculation of the potential payouts and profits if Horse #**5** were to win. In addition, each of FIGS. 4A through 4E illustrates the calculation of the potential payouts and profits before (or without) accounting for take-out and after (or with) accounting for take-out.

[0061]FIG. 4A illustrates a payout table **200**A and a stakes table **202**. Payout table **200**A indicates various payouts and profits assuming Horse #**1** were to win. Such payouts and profits are based at least on stakes table **202** and one or more calculations shown in FIGS. 3A and 3B.

[0062] Payout table **200**A includes various payouts and profits as calculated before-commission (BC), as indicated by row **206**A, and after-commission (AC), as indicated by row **204**A. A take-out rate of 15% is used in this example. However, it should be understood that any suitable take-out rate may be used. For each case, BC and AC, payout table **200**A indicates the take-out rate **208**A; the total stake on all horses, **210**A; the total stake on Horse #**1**, **212**A; the total win bet payout if Horse #**1** were to win, **214**A; the payout per win bet unit currency if Horse #**1** were to win, **216**A; the total win bet profit if Horse #**1** were to win, **218**A; the total group bet payout if Horse #**1** were to win, **220**A; the payout per group bet unit currency if Horse #**1** were to win, **222**A; and the total group bet profit if Horse #**1** were to win, **224**A.

[0063] Stakes table **202** includes a before-commission (BC) section **250** and an after-commission (AC) section **252**. BC section **250** indicates example current BC win bet stakes **254** on each horse, a current BC total of win bets on all horses **256**, a BC group-participant win bet pool **258**, an example current BC group bet pool **260**, and the BC allocation of the group bet pool, indicated by reference number **262**. AC section **252** indicates example current AC win bet stakes **270** on each horse, a current total of win bets on all horses **272**, an AC group-participant win bet pool **274**, an example current AC group bet pool **276**, and the allocation of the AC group bet pool, indicated by reference number **278**.

[0064] Various data within BC section **250** and AC section **252** may be determined using one or more calculations shown in FIGS. 3A and 3B. For example, regarding BC section **250**, the current BC total of win bets on all horses **256** may be determined using equation **136**; the BC group-participant win bet pool **258** may be determined using equation **132**; and the BC allocation of the group bet pool, indicated as **262**, may be determined using equation **136**.

[0065] Regarding AC section **252**, the current AC win bet stakes **270** on each horse may be determined using equation **102**; the current AC total of win bets on all horses **272** may be determined using equation **104**; the AC group-participant win bet pool **274** may be determined using equation **106**; the current AC group bet pool **276** may be determined using equation **100**; and the allocation of the AC group bet pool, indicated as **278**, may be determined using equation **110**.

[0066] In addition, as discussed above, the payouts and profits shown in payout table **200**A may be determined based on stakes table **202** using one or more calculations shown in FIGS. 3A and 3B. First, the various payouts and profits calculated with or after take-out, as indicated along row **204**A, may be determined using one or more calculations shown in FIGS. 3A. For example, the total stake on all horses (before take-out), **210**A, may be determined using equation **136**. The total AC stake on Horse #**1**, **212**A, may be determined using equation **112**, for example. The total AC win bet payout if Horse #**1** were to win, **214**A, may be determined using either equation **120**A or equation **120**B, for example. The AC payout per win bet unit currency if Horse #**1** were to win, **216**A, may be determined using either equation **124**A or **124**B, for example. In the example shown in FIG. 4A, the AC payout per win bet unit currency is defined as the AC payout per dollar wagered on a win bet on Horse #**1**. The total AC win bet profit if Horse #**1** were to win, **218**A, may be determined using equation **122**, for example. The total AC group bet payout if Horse #**1** were to win, **220**A, may be determined using either equation **114**A or **114**B, for example. The AC payout per group bet unit currency if Horse #**1** were to win, **222**A, may be determined using either equation **118**A or **118**B, for example. In the example shown in FIG. 4A, the AC payout per group bet unit currency is defined as the payout per dollar wagered on the group bet **24**. Finally, the total AC group bet profit if Horse #**1** were to win, **224**A, may be determined using equation **116**, for example.

[0067] Similarly, the various payouts and profits calculated without or before take-out, as indicated along row **206**A, may be determined using one or more calculations shown in FIGS. 3B. For example, the total BC stake on Horse #**1**, **212**A, may be determined using equation **138**. The total win bet payout if Horse #**1** were to win, **214**A, may be determined using either equation **146**A or **146**B, for example. The payout per win bet unit currency if Horse #**1** were to win, **216**A, may be determined using either equation **150**A or **150**B, for example. In the example shown in FIG. 4A, the payout per win bet unit currency is defined as the payout per dollar wagered on a win bet on Horse #**1**. The total win bet profit if Horse #**1** were to win, **218**A, may be determined using equation **148**, for example. The total group bet payout if Horse #**1** were to win, **220**A, may be determined using either equation **140**A or **140**B, for example. The payout per group bet unit currency if Horse #**1** were to win, **222**A, may be determined using either equation **144**A or **144**B, for example. In the example shown in FIG. 4A, the payout per group bet unit currency is defined as the payout per dollar wagered on the group bet **24**. Finally, the total group bet profit if Horse #**1** were to win, **224**A, may be determined using equation **142**, for example.

[0068] In this manner, the various payouts and profits included in payout table **200**A may be determined for situations both with and without take-out. As discussed above, the various payouts and profits included in payout table **200**A are relevant in the event that Horse #**1** wins the race. FIGS. 4B, 4C, **4**D and **4**E illustrate payout tables **200**B, **200**C, **200**D and **200**E, respectively, which indicate the relevant payouts and profits in the event that Horse #**2**, Horse #**3**, Horse #**4** or Horse #**5**, respectively, wins the race.

[0069] In view of FIGS. 4A, 4B, **4**C and **4**E, it can be seen that the potential total group bet payout (indicated as **220**A, **220**B, **220**C and **220**E, respectively) is the same ($4,000 without take-out and $3,400 with a 15% take-out rate) if any of the horses covered by the group bet **24** (Horses #**1**, #**2**, #**3** and #**5**) win the race. However, as shown in FIG. 4D, it can be seen that the potential total group bet payout **220**D if the favorite horse (Horse #**4**) wins is zero. It should be understood that in some alternative embodiments, the potential total group bet payout may not be different depending on which of the grouped participants wins the event.

[0070]FIG. 4F illustrates a payout table **240** which includes the potential after-commission payouts and profits for each of the five horses as determined above with reference to FIGS. 4A through 4E. In other words, table **240** combines the after-commission rows shown in FIGS. 4A through 4E as rows **204**A, **204**B, **204**C, **204**D and **204**E.

[0071]FIG. 5 is a flowchart illustrating an example method of receiving, managing, and paying win bets **22** and group bets **24** in accordance with an embodiment of the present invention. At step **300**, win bets **22** are received from one or more clients **20** via one or more betting system interfaces **14**, such as described above with reference to FIG. 1. For example, in the example horse race discussed above with reference to FIGS. 4A through 4F, assume various win bets **22** are received which create the win bet stakes for each horse shown in column **254** of FIG. 4A. At step **302**, group bets **24** are received from one or more clients **20** via one or more betting system interfaces **14**, such as described above with reference to FIG. 1. For example, in the example discussed above, assume various wagers are received on the group bet **24** covering Horses #**1**, #**2**, #**3** and #**5** which creates a before-commission group bet pool **260** of $2,000 as shown in FIG. 4A. In some situations, steps **300** and **302** may be occur simultaneously, or may at least partially overlap.

[0072] Each win bet **22** or group bet **24** received at steps **200** and/or **302** may be stored at step **304**, such as within memory **40**, for example. A take-out (commission) rate may be applied to each received win bet **22** and group bet **24** at step **306**, such as described above with reference to FIG. 4A. For example, regarding win bets **22**, a take-out rate of 15% may be applied to received win bets **22** shown in column **254** of FIG. 4A to generate the after-commission win bet stakes for each horse shown in column **270** of FIG. 4A. Similarly, a take-out rate of 15% may be applied to each group bet **24**, or to the group bet pool **260**, to generate the after-commission group bet pool **276** of $1,700, as shown in FIG. 4A.

[0073] At step **308**, each received group bet **24** may be divided and allocated among all participants covered by the group bet **24**, or all grouped participants, such that the potential payout for the group bet **24** is related to the odds on the favorite participant, such as described above with reference to FIGS. 1 and 4A. For example, the after-commission group bet pool **276** may be divided an allocated as shown in column **278** of FIG. 4A.

[0074] At step **310**, various odds, payouts and/or profits for some or all received and/or stored win bets **22**, such as various current odds **50** or various payouts and profits shown in FIGS. 4A through 4F, for example, may be determined by betting system platform **16**. For example, in the example discussed above, various win bet payouts and profits shown in table **200**A of FIG. 4A (and similarly for those shown in tables **200**B, **200**C, **200**D and **200**E shown in FIGS. 4A, 4B, **4**C and **4**D, respectively) may be determined at step **310**, such as the total win bet payout if Horse #**1** were to win, **214**A; the payout per win bet unit currency if Horse #**1** were to win, **216**A; and the total win bet profit if Horse #**1** were to win, **218**A. Step **310** is described in greater detail with reference to FIG. 6.

[0075] At step **312**, various odds, payouts and/or profits for some or all received and/or stored group bets **24**, such as various current odds **50** or various payouts and profits shown in FIGS. 4A through 4F, for example, may be determined by betting system platform **16**. For example, in the example discussed above, various group bet payouts and profits shown in table **200**A of FIG. 4A (and similarly for those shown in tables **200**B, **200**C, **200**D and **200**E shown in FIGS. 4A, 4B, **4**C and **4**D, respectively) may be determined at step **312**, such as the total group bet payout if Horse #**1** were to win, **220**A; the payout per group bet unit currency if Horse #**1** were to win, **222**A; and the total group bet profit if Horse #**1** were to win, **224**A. Step **312** is described in greater detail with reference to FIG. 7.

[0076] At least portions of steps **310** and **312** may be performed simultaneously. In addition, in some embodiments, steps **310** and **312** are performed in real time, substantially in real time, or at preset intervals (such as every 30 seconds, for example) as win bets **22** and/or group bets **24** are received by betting system platform **16**.

[0077] At step **314**, it is determined whether the betting pool is closed. In some embodiments, the betting pool, which includes all bets on the event to be considered in the final determination of payouts, may be closed substantially at the time of or after betting is closed on the event. For example, in some embodiments, bets which are made prior to the close of betting but are processed (at least partially) after the close of betting (such as due to processing and transmission delays, for example) may be included within the betting pool.

[0078] If the betting pool is still open, the method may return to steps **300** through **312** to receive and store additional win bets **22** and/or group bets **24**, and to recalculate the current odds, payouts and/or profits. In this manner, betting system platform **16** may update the current odds, payouts and/or profits associated with the various bets **12** associated with the event. In some embodiments, betting system platform **16** may perform such updates continuously and/or in real time, substantially in real time, or at preset intervals (such as every 30 seconds, for example).

[0079] Thus, it should be understood that each time the method returns to steps **300** through **312** while the betting pool remains open, the allocation of the group bet pool is recalculated at step **308** for newly received win bets **22** and/or group bets **24**. In this manner, the allocation of the group bet pool may be continuously (or at preset intervals) updated in order to provide the appropriate win bet and group bet payouts (which are determined at steps **310** and **312**, respectively.)

[0080] If it is determined at step **314** that the betting pool is closed, the method proceeds to step **316**. At step **316**, it is determined whether any of the participants in the event will not be competing in the event, such as if a participant is scratched, withdrawn, or becomes a non-runner, for example. For example, betting system platform **16** may receive a notification that one or more of the participants has been withdrawn from the event prior to the start of the event. If it is determined at step **316** that one or more participants will not be competing in the event, the method may return to step **308** to recalculate the allocation of the group bet pool based on the updated set of participants in the event. Otherwise, the method may proceed to step **318**. In an alternative embodiment, if it is determined at step **316** that one or more participants will not be competing in the event, all group bets **24** may be cancelled, and refunds may be issued for such group bets **24**. It should be understood that step **318** may be performed before, after, or both before and after step **314**.

[0081] At step **318**, the results of the event are received, such as the final position of each participant in the event and whether there was a tie for any position, for example. At step **320**, win bet payouts may be distributed to clients **20** who made win bets **22** on the winning participant. For example, assuming in the example discussed above that Horse #**1** won the race, win bet payouts may be distributed to clients **20** who made win bets **22** on Horse #**1**, which payouts may be based on payouts determined at step **310**, such as payout per win bet unit currency if Horse #**1** were to win, **216**A, for example. In some embodiments, win bet payouts may be distributed according to the final determination of win bet payouts made at step **310**. In alternative embodiments, win bet payouts may be distributed according to a final determination of win bet payouts made after the betting closed or even after the event was completed.

[0082] At step **322**, group bet payouts may be distributed to clients **20** who made winning group bets **24**. For example, assuming in the example discussed above that Horse #**1** won the race, the group bet **24** is a winning bet, and thus group bet payouts may be distributed to all clients **20** who wagered on the group bet **24**. Such group bet payouts may be based on payouts determined at step **312**, such as payout per group bet unit currency if Horse #**1** were to win, **222**A, for example. In some embodiments, group bet payouts may be distributed according to the final determination of group bet payouts made at step **312**. In alternative embodiments, group bet payouts may be distributed according to a final determination of group bet payouts made after the betting closed or even after the event was completed. In some situations, steps **320** and **322** may be occur simultaneously, or may at least partially overlap.

[0083]FIG. 6 is a flowchart illustrating an example method of determining various odds, payouts and/or profits for win bets **22**, such as described above with reference to step **314** shown in FIG. 5. This method may be used to determining various odds, payouts and/or profits for win bets **22** associated with each participant in an event. For example, in the example discussed above, the method may be used to determine the payouts for win bets **22** made on each of the five horses. At step **340**, a participant in the set of participants in the event is selected. For example, in the example discussed above, Horse #**1** may be selected first, and steps **342** through **350** may then be performed to determine the total win bet payout for win bets **22** made on Horse #**1**.

[0084] At step **342**, the total after-commission (AC) stake on all non-selected participants is determined. For example, equation **112** shown in FIG. 3B may be used to determine the total stake of each non-selected participant, and the total stake of each non-selected participant may be added together. In the example discussed above, the total after-commission (AC) stake on all non-selected participants is the total AC stake on Horses #**2**, **3**, **4** and **5**, which equals $10,710, as determined by adding the win bet and group bet stakes for Horses #**2**, **3**, **4** and **5**, as shown in columns **270** and **278** of table **202** shown in FIG. 4A.

[0085] At step **344**, the total AC stake on the selected participant is determined, such as using equation **112** shown in FIG. 3B. In the example discussed above, the total AC stake on Horse #**1** is $1,190, as shown in column **212**A of table **200**A shown in FIG. 4A. The total AC win bet stake on the selected participant is determined at step **346**. In the example discussed above, the total AC win bet stake on Horse #**1** is $850, as shown in column **270** of table **202** shown in FIG. 4A.

[0086] At step **348**, the total AC win bet payout for the selected participant is determined, such as using either equation **120**A or **120**B shown in FIG. 3B. In the example discussed above, the total AC win bet payout for Horse #**1** is $8,500, as shown in column **214**A of table **200**A shown in FIG. 4A.

[0087] At step **350**, the AC payout per win bet unit currency for the selected participant is determined, such as using either equation **124**A or **124**B shown in FIG. 3B. This may comprise, for example, determining the payout per one dollar wagered on a win bet on the selected participant.

[0088] At step **352**, it is determined whether there are any more participants in the set of participants in the event. If so, the method returns to repeat steps **340** through **350** for each remaining participant. If not, the method ends. For example, in the example discussed above, **340** through **350** are repeated for Horses #**2**, **3**, **4** and **5** to determine the payouts for win bets **22** made on each of the Horses #**2**, **3**, **4** and **5**.

[0089]FIG. 7 is a flowchart illustrating an example method of determining various odds, payouts and/or profits for group bets **24**, such as described above with reference to step **318** shown in FIG. 5. For example, in the example discussed above, the method may be used to determine the payouts for group bets **24**. At step **360**, a participant in the set of participants in the event is selected. Steps **362** through **370** are then performed, as discussed below, to determine the group bet payout if the selected participant were to win the event. For example, in the example discussed above, Horse #**1** may be selected first at step **360** to determine (at steps **362** to **370**) the group bet payout if Horse #**1** were to win the race.

[0090] At step **362**, the total after-commission (AC) stake on all non-selected participants is determined. For example, equation **112** shown in FIG. 3B may be used to determine the total stake of each non-selected participant, and the total stake of each non-selected participant may be added together. In the example discussed above, the total after-commission (AC) stake on all non-selected participants is the total AC stake on Horses #**2**, **3**, **4** and **5**, which equals $10,710, as determined by adding the win bet and group bet stakes for Horses #**2**, **3**, **4** and **5**, as shown in columns **270** and **278** of table **202** shown in FIG. 4A.

[0091] At step **364**, the total AC stake on the selected participant is determined, such as using equation **112** shown in FIG. 3B. In the example discussed above, the total AC stake on Horse #**1** is $1,190, as shown in column **212**A of table **200**A shown in FIG. 4A. The AC portion of the group bet allocated to the selected participant (such as at step **312** shown in FIG. 5) is determined at step **366**. In the example discussed above, the AC portion of the group bet allocated to Horse #**1** is $340, as shown in column **278** of table **202** shown in FIG. 4A.

[0092] At step **368**, the total AC group bet payout if the selected participant were to win the event is determined, such as using either equation **114**A or **114**B shown in FIG. 3B. In the example discussed above, the total AC group bet payout if Horse #**1** were to win the race is $3,400, as shown in column **220**A of table **200**A shown in FIG. 4A.

[0093] At step **370**, the AC payout per group bet unit currency for the selected participant is determined, such as using either equation **118**A or **118**B shown in FIG. 3B. This may comprise, for example, determining the payout per one dollar wagered on the group bet **24**.

[0094] At step **372**, it is determined whether there are any more participants in the set of participants in the event. If so, the method returns to repeat steps **360** through **370** for each remaining participant. If not, the method ends. For example, in the example discussed above, **360** through **370** are repeated for Horses #**2**, **3**, **4** and **5** to determine the payouts for group bets **24** if each of the Horses #**2**, **3**, **4** and **5** were to win the race.

[0095] It should be understood that in various embodiments, the steps of the methods shown in FIGS. 5, 6 and **7** may be performed in any suitable order and may overlap in whole or in part without departing from the scope of the present invention. In addition, various steps and methods shown in FIGS. 5, 6 and **7** may be performed in serial or parallel, notwithstanding the example representations shown in FIGS. 5, 6 and **7**. For example, as discussed above, in some embodiments, steps **310** and **312** shown in FIG. 5 may be performed after step **314**. As another example, steps **320** and **322** shown in FIG. 5 may be performed in series or in parallel without departing from the scope of the invention.

[0096] Although embodiments of the invention and their advantages are described in detail, a person skilled in the art could make various alterations, additions, and omissions without departing from the spirit and scope of the present invention as defined by the appended claims.
