1. Field of the Invention
The present invention is directed to group play gaming and methods and, more particularly, to gaming networks and methods for group play gaming.
2. Description of the Related Art
In the prior art, various types of gaming machines have been developed with different features to captivate and maintain player interest. In general, a gaming machine allows a player to play a game in exchange for a wager. Depending on the outcome of the game, the player may be entitled to an award which is paid to the player by the gaming machine, normally in the form of currency or game credits. Gaming machines may include flashing displays, lighted displays, or sound effects to capture a player's interest in a gaming device.
Gaming tournaments are a popular practice in casinos. A slot machine tournament is a group activity in which a player pays an entry fee to join the tournament. The gaming machines used for a tournament are usually configured specifically for tournament play with high win frequencies. Upon the start of the tournament, a controller enables all machines for play and the players play as rapidly as they can to accumulate points “paid” for winning outcomes on the game. At the end conclusion of the tournament, usually a fixed period of time, all of the slot machines are disabled by the controller. The points accumulated by each machine are ranked and a set of participants having the highest accumulated number of points are declared the winners and awarded predetermined portions of the entry fees.
Most tournaments require dedicated personnel and a section of the casino floor allocated to the operation of the tournament. More recently, automated control of slot machine tournaments including slot machines that can be operated as normal slot machines when not in use for a tournament have become known. An example of such a system is disclosed in U.S. Pat. No. 6,287,202. One disadvantage of tournaments to players is that the prize pool is of limited size. The prizes to be awarded are fixed and the amounts may not provide much incentive for a player to play. Another disadvantage is that many participants in a tournament win nothing at all and lose their entire entry fee. In addition, a tournament operates on a known start and stop schedule, providing little mystery or anticipation on the part of players.
While tournaments and other group play activities such as table games have been very successful, there remains a need for group games that provide a player with enhanced excitement and increased opportunity of winning
In accordance with one or more embodiments of the invention, a networked group play gaming system includes a group play controller and a plurality of gaming machines linked with the group play controller by a network. Upon receipt of a trigger from one of the gaming machines, the group play controller causes group play to begin for various prizes.
In accordance with one or more other embodiments of the invention, a method of operating a group play gaming network includes the steps of connecting a group play controller to a plurality of gaming machines through a network, initiating a group play trigger at one of the gaming machines and determining eligibility of the remaining gaming machines for group play. In accordance with another aspect, for each eligible machine, the method includes determining a set of group play outcomes, ranking the eligible machines according to their respective sets of outcomes and, upon conclusion of group play, according to the ranking, awarding a progressive prize to a player of one of the gaming machines.
Other features and advantages will become apparent from the following detailed description, taken in conjunction with the accompanying drawings, which illustrate by way of example, the features of the various embodiments.
Various embodiments are directed to a networked gaming system, gaming machines and game and their associated methods for playing a group play game. Embodiments of one or more games, gaming machines, networked gaming systems and methods are illustrated and described herein, by way of example only, and not by way of limitation. Referring now to the drawings, and more particularly to
In accordance with one or more embodiments of the invention,
In one or more embodiments, group play mode is initiated by an event at one of the participating gaming machines. For example, a game in accordance with one or more aspects of the invention, a group play game may be one of a set of primary games randomly selected for play following initiation of gaming machine play by the player. For example, U.S. application Ser. No. 11/428,220, entitled “Multiple Primary Games Triggered by Random Number Generator,” filed on Jun. 30, 2006, hereby incorporated in by reference its entirety, discloses a gaming machine including at least two distinct primary games. After receiving a wager, the gaming machine determines which primary game to activate. In accordance with one or more embodiments of the invention, group play mode may be initiated when one of the participating gaming machines selects a group play primary game, at which time the group gaming controller notifies other potentially eligible networked gaming machines of the event and invites them to join group play if eligible. Eligible machines accept and, if two or more gaming machines are eligible for group play, group play ensues. In accordance with one or more embodiments, more than one group play game is available for random selection once a triggering event has occurred. In another embodiment, the player of the gaming machine that causes the triggering event is allowed to select one from a set of group play games.
In accordance with one embodiment, during group play, normal operation of the slot machines is suspended, at which time players participate in group game such as a tournament, accumulating points for winning outcomes on their gaming machines according to a group play pay table rather than a standard pay table. In one or more embodiments, play of one or more group games does not require a wager.
At the end of the tournament, the players are ranked according to their accumulated points. In one or more embodiments, prizes are awarded according to the rankings. In still other embodiments, some players are eligible for progressive award prizes. For example, the three players with the top point totals may qualify to receive one of a set of progressive awards if they have earned enough points during the tournament. In one or more embodiments, the number of progressive awards in the set is five, but the number of progressive awards may vary. Those players not eligible for a progressive prize based on either their finishing position (1st, 2nd, 3rd etc.) or their total tournament points may receive a consolation prize. In one or more embodiments, the consolation prize is a multiple of the player's last wager prior to the start of the tournament.
The current points for each gaming machine and intermediate and final standings for each of the machines may be displayed on gaming machines 101-106. In one or more embodiments, tournament status information is also displayed on a shared gaming display 120 as part of a sign 110. Sign 110 may be controlled by a gaming display control computer (not shown), described further below. Once all tournament prizes have been awarded, gaming machines 101-106 resume normal stand-alone operation until the next group play tournament is triggered.
In accordance with one or more embodiments, gaming machines 220 may be, by way of example and not by limitation, CineReel™ slot machines running the Alpha OS gaming software platform by Bally Technologies, Inc. In various embodiments, any of the gaming machines 220 may be a mechanical reel spinning slot machine, video slot machine, video poker machine, keno machine, video blackjack machine, or a gaming machine of any other type provided it can be operatively connected to the network for participation in group play. In one or more embodiments, gaming machines 220 may provide one or more games as a set of multiple primary games with an individual game selected for play by a random number generator.
Group play controller 240 facilitates the transfer of information concerning group play events to and from gaming machines connected to the network. In one or more embodiments, when a gaming machine 220 initiates the group play feature, it notifies group play controller 240. Group play controller 240 then forwards this information to all machines 220 on the network 250. Group play controller 240 waits for an acknowledgement from all machines 220, then directs all eligible machines 220 to start a group play feature. During group play, each machine 220 transmits its current group play status, for example, current tournament points, to group play controller 240. Group play controller 240 may then forward this to the other participating gaming machines 220 or use this information to display a leader-board or other group play information on display 250. For example, these displays may include progressive pool amounts, tournament standings and the like.
In accordance with one or more embodiments of the invention, group play displays may be presented on displays operated by a separate display control computer (not shown), such as a reconfigurable gaming display. An example of a reconfigurable display control computer, such as a SignStudio™ by Bally Technologies, Inc., is disclosed in U.S. application Ser. No. 11/463,793, entitled “Reconfigurable Gaming Display and System,” filed on Aug. 10, 2006, which is hereby incorporated by reference in its entirety.
In accordance with one or more aspects of the invention, during its boot sequence, a gaming machine 220 attempts to connect to the group play controller 240 using TCP/IP. Gaming machine 220 transmits a registration package containing a unique identifier for that machine. Group play controller 240 may respond with either an approval or denial packet. For example, a denial packet could be sent if group play controller 240 already has a maximum number of allowed gaming machines 220 registered.
In one embodiment, the first machine 220 to register with group play controller 240 is sent a packet enabling it as a “master progressive communicator.” During regular game play, the master progressive communicator periodically transmits a packet to the group play controller 240 containing the current progressive amounts, which gaming machine 220 has in turn received from progressive controller 230. Group play controller 240 computer may use these packets to update progressive pool “odometers” on one or more displays 250.
Progressive controller 230 may be a known industry-standard progressive controller such as a controller manufactured by Mikohn, Inc. Progressive controller 230 monitors wagering during regular play at each of the gaming machines 220, calculates a current value for one or more progressive jackpot pools and transmits the current pool values to the gaming machines 220. In one or more embodiments, group play progressive awards are accumulated during regular play as a percentage, such as three percent, of the regular game play take. The prizes may be sized according to the preferences of the casino operator. In one instance, there may be three awards, wherein first place is awarded 50% of the money withheld for progressives, second place is awarded 30% of the money withheld for progressives and third place is awarded 20% of the money withheld for progressives. The number of prizes may vary without deviating from the scope of the invention. The size of the prizes is dependent on the amount of play prior to initiating group play. In one or more embodiments, machines not eligible for group play at its initiation may be in regular play during a group play period and may continue to contribute to progressive pools that may be won by one or more of the machines in group play. In another aspect, the prizes may be set amounts established by the casino operator from non-coin-in funds, such as marketing funds.
In the event of a winning jackpot at one of the gaming machines 220, the gaming machine notifies progressive controller 220 that a particular jackpot has occurred. Progressive controller 230 calculates a final progressive jackpot value and broadcasts the amount and the winning event to each of the gaming machines 220. Progressive controller 230 then resets the value of the won progressive pool to a predetermined starting point. In some embodiments, the connection between progressive controller 230 and gaming machines 220 is the same as the connection between the other network components. In other embodiments, the connection between the progressive controller 230 and the gaming machines 220 is a different hardware and software connection, for example, RS-232. In accordance with one or more aspects of the invention, one of the gaming machines 220 may be assigned the role of passing progressive pool information received from progressive controller 230 to group play controller 240. In one or more embodiments, group play controller 240 has a dedicated connection to progressive controller 230 for the purpose of monitoring progressive pool status in order to update display 250 with the values of the various progressive pools.
In one or more alternate embodiments of the invention, progressive controller 220 may be implemented as past of the software functionality of one or more of the gaming machines 220. In still other embodiments, progressive controller 220 may be implemented as part of the software functionality of group play controller 240.
One or more embodiments of the network include a TCP/IP connection 260 between router 210, group play controller 240 and gaming machines 220. Any compatible means for operatively linking the various devices may be used such as CAT5 ethernet cable or a wireless connection. Other embodiments provide different hardware and protocol implementations, for example, an RS-485 network may be used to form connection 260. In one or more embodiments, machines 220 periodically transmit a ‘ping’ packet to, and in return receive a ‘pong’ packet from, group play controller 240 to ensure that group play controller computer 240 knows that all machines 220 are operational and that the machines 220 know that group play controller 240 is operational. In one or more embodiments, group play controller 240 and machines 220 may detect if the TCP/IP communication line is broken using capabilities of the TCP/IP protocol.
In the example embodiment shown in
One will appreciate that a gaming system is accordance with one or more aspects of the invention may also include other types of components, and the above illustrations are meant only as examples and not as limitations to the types of networking components, gaming machines or games. For example, group play controller 240 may be part of a central host computer system, such as a player tracking host or a “back-end” server. Group play controller 240 may be part of the logic of one or more of gaming machines 220. For example, the triggering gaming machine 220 may be enabled as the current “master” group play controller, coordinating all other gaming machines in group play. In accordance with still other embodiments, multiple group play features may be “queued” by one or more group play controllers. For example, a gaming machine 220 unqualified for group play may itself trigger a group play event while one is already in progress. In this case, a new group play event trigger would be sent to the machines 220 on the network as soon as the first group game was complete. In accordance with one or more embodiments, multiple group play events, each with its gaming machine 220 acting as a “master” group play controller 240, may be played concurrently on the same group play network. Additionally, it may further be appreciated that each of the games could be operated on a remote host computer such that a player initiates play with the host computer over a network via a player interface and each gaming machine 220 operates the respective gaming and video displays in conjunction with the game whose play is controlled by the remote computer.
A logical flow diagram generally depicting the steps associated with an example method 300 for carrying out a group play event in accordance with one or more aspects of the invention is presented in
The gaming machine makes an “instant win” determination at step 302 to determine if a group play game should be played. An “instant win” is a game triggered by an event not related to a game play outcome, one or more examples of which are disclosed in U.S. application Ser. No. 11/428,220, entitled “Multiple Primary Games Triggered by Random Number Generator,” filed on Jun. 30, 2006, hereby incorporated in by reference its entirety. Briefly, after receiving a wager, the gaming machine determines which of one or more primary game to activate. In one or more embodiments of the present invention, an instant win determination occurs when a “spin,” “repeat bet,” or “max bet” button is pressed by a player at one of the linked gaming machines. A random number is selected from a random number range, for example, 1-192. If the selected number does not match a predetermined value within the range, for example, the predetermined value is “1” and the selected value is one of the set of values from 2-192, inclusive, normal game play occurs at step 304. Any award(s) for winning outcome(s) are paid to the player at step 305 and control returns to step 302 for another normal play of the gaming machine.
If, however, the random number drawn at step 303 matches the predetermined value within the range, again, for example, “1”, the group play game is triggered in lieu of normal play on the gaming machine. It should be noted that the triggering gaming machine may be, at a given moment, any of the gaming machines connected to the group play network.
If the instant win determination is true at step 303, the triggering gaming machine sends a group play trigger message to a group play controller at step 306. In response, the group play controller forwards the group play trigger message to all other gaming machines connected to the group play controller at step 307.
If a receiving gaming machine is busy, in the middle of a game, for example, when the group play trigger message is received at step 308, the machine completes the current game and pays any associated wins at step 309. Once the gaming machine is not busy, it determines whether it is eligible to participate in group play according to pre-established rules. By way of example, and not by limitation, any connected machine that did not trigger the feature may participate in group play if it performed a normal game play within ten seconds of the time the group play trigger message was received. It will be appreciated that the triggering gaming machine is automatically eligible for the group play. Each gaming machine responds to the group play trigger message with its eligibility status (eligible or not eligible) to the group play controller at step 310.
The Group play controller sends the number of eligible gaming machine s (e.g., 6 of 8 machines) to all connected gaming machines at step 312. At step 313, each gaming machine computes and sends the server the number of tournament points which should be assigned to the gaming machine at the start of the tournament. For example, box 311 provides an example lookup table used for assigning starting tournament points based on the number of eligible gaming machines and the number of credits wagered in the last normal game played. Rewarding players with higher wagers with a “head start” in group play may encourage players to wager more money during regular game play. In accordance with some embodiments, each gaming machine has a different table based on its game math model. In one embodiment, all starting point tables are the same.
In some embodiments, the number of gaming machines participating in the tournament and an individual gaming machine's wager size may determine its “eligibility level.” A gaming machine's eligibility level may determine both the number of starting tournament points and which of a set of tournament point pay tables will be used during group play. For example, a winning outcome of a single CHERRY symbol might award one tournament point for a machine operating at eligibility level 1, whereas an identical machine operating at eligibility level 3 might be awarded three tournament points for the same winning game outcome. Allowing players with higher wagers during regular game play to accrue points in group play at a faster rate than those with lower normal game wagers may also encourage players to wager more money during regular game play.
Once all eligible gaming machines are ready, group play can begin. The group play controller sends a start group play command to all eligible gaming machines at step 314. The eligible gaming machines reconfigure themselves for group play, consisting, for example, of ten free games with a maximum time-out limit at step 315. The players at all eligible gaming machines are notified of the group play rules, and told to begin group play, step 316. Players may or may not interact with their gaming machine controls during group play, depending on the game being played. For example, a poker game might require player interaction while a slot machine game might not. In accordance with one or more embodiments, each gaming machine may be allowed a different number of free games according to the amount of the last wager during regular play. For example, a max bet player may be awarded additional bonus games over non-max bet players. Allowing players with higher wagers during regular game play more chances to accrue points in group play those with lower normal game wagers may encourage players to wager more money during regular game play.
All eligible gaming machines initiate a free game at step 317. Each gaming machine checks the game outcome to see if it was a winning outcome according to the gaming machine's group play pay table at step 318. If not, the gaming machine checks to see if time has expired or if the game, for example, the tenth game, has been performed at step 319. If not, control returns to step 317 for another game. If a winning outcome was determined in step 318, the tournament point total for the winning gaming machine is incremented by the points earned for the outcome at step 320.
Each gaming machine sends it current point total to the group play controller at step 321. The group play controller uses the point total for display purposes, updating a leader board at step 322. The leader board may be replicated on a plurality of displays. The leader board is updated and may graphically display the threshold reached by each gaming machine with a corresponding arrow in a bar graph visually depicting the “upward” progress of all gaming machines. The leader board may be displayed on one or more displays controlled by a gaming display control computer or by the group play controller. A example of a leader board in accordance with one or more embodiments of the invention may be similar to the table shown in box 325.
Group play continues recursively for all eligible gaming machines between steps 317-322 as described above until each gaming machine determines it has completed its final spin in group play at step 319. As each gaming machine completes its final game in group play, it sends its final tournament point total to the group play controller at step 323. The group play controller updates the leader board at step 324. Control then passes to step 325,
The group play controller calculates a ranked points leader list based on the final point total of each participating gaming machine at step 325. The group play controller sends the ranked list to the highest ranked un-notified gaming machine at step 326. The group controller recursively performs steps 326 and 331 until all gaming machines on the list have received and processed it at steps 327-335.
Each of the gaming machines compares its final ranking and final point total to an internal a bonus round pay table to determine if it is in the top three finishing positions and, if so, whether the total points meet or exceed a threshold required to win a progressive award at step 327. In one embodiment, which progressive has been won depends on the total number of points achieved. In another embodiment, one of a set of progressives is randomly chosen as the won progressive.
If a progressive award has been won, the gaming machine notifies the progressive controller at step 328, otherwise, control passes to step 333, described below. Upon notification of a progressive win, the progressive controller returns the amount of the designated progressive award to the winning gaming machine and the progressive pool is reset to a new starting value at step 329. The progressive award may be paid by way of hand pay, voucher or credits placed on the credit meter of the gaming machine. In one or more embodiments, the value associated with the progressive award may be placed directly into a system account associated with the winning player. The gaming machine next sends a message to the group play controller that a progressive award has been completed at step 330. A check for any gaming machines on the ranked points leader list that have not yet received the list is performed at step 331. If any un-notified gaming machines remain, control returns to step 326 for the next gaming machine in the list. Otherwise, group play is complete. The group play controller sends a message to all gaming machines to return to regular game play at step 332 and control returns to step 302,
If, at step 327, above, a progressive prize has not been won due to an insufficient number of points, the gaming machine then determines whether it is in the top three finishing positions at step 333. If so, a bonus multiplier, for example, 3×, is applied to the wager made in the last played regular game, and the resulting prize is awarded at step 334. If the gaming machine is not one of the top three ranked gaming machines, a consolation prize, which may also be a multiplier, for example, 2×, is applied to the wager made in the game last played in the last played regular game, and is awarded at step 337. In one or more embodiments, the consolation prize is a fixed amount. Following the payment of a non-progressive award, the gaming machine sends a message to the group play controller that the award is complete at step 335. As described above, a check for any gaming machines on the ranked points leader list that have not yet received the list is performed at step 331. If any un-notified gaming machines remain, control returns to step 326 for the next gaming machine in the list. Otherwise, group play is complete. The group play controller sends a message to all gaming machines to return to regular game play at step 332 and control returns to step 302,

This information may be generated through a host computer networked with gaming machine 400 on its own initiative or it may be obtained by request of the player using either one or more of the plurality of player-activated buttons 460; the game display itself, if game display 440 comprises a touch screen or similar technology; buttons (not shown) mounted about game display 440 which may permit selections such as those found on an ATM machine, where legends on the screen are associated with respective selecting buttons; or any player input device that offers the required functionality.
Cabinet housing 420 incorporates a single game display 440. However, in alternate embodiments, cabinet housing 420 or top box 450 may house one or more additional displays 453 or components used for various purposes including additional game play screens, animated “top glass,” progressive meters or mechanical or electromechanical devices (not shown) such as, but not limited to, wheels, pointers or reels. The additional displays may or may not include a touch screen or touch glass system.
In accordance with one embodiment of the present invention,
When a player has inserted a form of currency such as, for example and without limitation, paper currency, coins or tokens, cashless tickets or vouchers, electronic funds transfers or the like into currency acceptor 510, a signal is sent to CPU 505 which, in turn, assigns an appropriate number of credits for play. The player may further control the operation of the gaming machine, for example, to select the amount to wager via electromechanical or touchscreen buttons 550. The game starts in response to the player pushing one of buttons 550 or an alternate start mechanism such as a handle or touchscreen icon (not shown). Random number generator 540 responds to instructions from CPU 505 to provide a display of randomly selected indicia on reels 530. In some embodiments, random generator 540 may be physically separate from gaming machine 400; for example, it may be part of a central determination host system (not shown) which provides random game outcomes to CPU 505. Thereafter, the player may or may not interact with the game through electromechanical or touchscreen buttons 550 to change the displayed indicia. Finally, CPU 505 under control of game program 520 compares the final display of indicia to a pay table. The set of possible game outcomes may include a subset of outcomes related to the triggering of a feature game. In the event the displayed outcome is a member of this subset, CPU 505, under control of game program 520, may cause feature game play to be presented on feature display 570.
In one embodiment, reels 530 are electromechanical reels. Game program 520 includes reel spinning firmware to provide proper signals for driving multiple stepper motors (not shown), which, in turn, spin the reels 530. Preferably, the motors are driven using a “full step” excitation sequence in which a single motor step is preformed by changing the excitation on one of the two-phase inputs in a specified sequence. The sequence determines whether the direction implemented is forward or reverse. The reel drive pulse trains go through three distinct stages: acceleration, steady state, and deceleration. During acceleration, reels 530 are driven with a pulse frequency that is less than the maximum “start/stop” frequency. Typically, if a motor is attempted to be started with a high frequency pulse, the motor loses synchronization and slips. Therefore, preferably the drive frequency is incrementally increased until the steady state drive frequency is reached. At steady state, reels 530 are driven for a specified number of steps at the maximum drive frequency before going to the deceleration phase. During deceleration, the process is reversed and the drive frequency decreased until the stopping frequency is reached. Preferably, this procedure helps to prevent reels 530 from slipping past the proper stop position on deceleration. Finally, at the stopping point, the motor excitation signals are held constant.
In one embodiment, the primary game reels are not used for the feature play; instead, a wheel or other feature display 570 is used to present the feature game outcomes. The feature display may be an electromechanical device, may present the feature on a video display or both.
Predetermined payout amounts for certain outcomes, including feature game outcomes, are stored as part of one or more game programs 520. Such payout amounts are, in response to instructions from CPU 505, provided to the player in the form of coins, credits or currency via payout mechanism 560, which may be one or more of a credit meter, a coin hopper, a voucher printer, an electronic funds transfer protocol or any other payout means known or developed in the art.
In various embodiments of gaming machine 400, game program(s) 520 is/are stored in a memory device (not shown) connected to or mounted on the gaming motherboard. By way of example, but not by limitation, such memory devices include external memory devices, hard drives, CD-ROMs, DVDs, and flash memory cards. In an alternative embodiment, the game programs are stored in a remote storage device. In one embodiment, the remote storage device is housed in a remote server. The gaming machine may access the remote storage device via a network connection, including but not limited to, a local area network connection, a TCP/IP connection, a wireless connection, or any other means for operatively networking components together. Optionally, other data including graphics, sound files and other media data for use with gaming machine 400 are stored in the same or a separate memory device (not shown). Some or all of game programs 520 and associated data may be loaded from one memory device into another, for example, from flash memory to random access memory (RAM).
An example game in accordance with one or more aspects of the invention is shown in
The player initiates game play by pressing a SPIN button (not shown). In some embodiments, the player may simultaneously select all pay lines at the maximum number of coins or credits allowed per line by pressing a MAX BET button. Buttons (see
In accordance with one embodiment, part of an example pay table 700 is shown in
In various embodiments, winning combinations may be evaluated across adjacent reels from left-to-right, from right-to-left or both. Additional winning combinations may be awarded when certain indicia do not necessarily accumulate adjacently on a pay line, but rather, appear anywhere on the reels (i.e., “scatter pays”). In addition, “wild” indicia may be used to complete winning combinations. Some “wild” indicia may also cause completed winning combinations to be result in pay amounts in excess of the normal winning combination by way of multiplication or addition, for example, a wild doubler symbol may be used.
As described above, an “instant win” may trigger play of a group play game. In one embodiment, a wager of a certain amount may be required in order to be eligible for participation in group play. For example, the player may be required to play the maximum wager in order to be eligible.
In various embodiments, any of the gaming machines 1050 may be a mechanical reel spinning slot machine, video slot machine, video poker machine, keno machine, video blackjack machine, or a gaming machine offering one or more of the above described primary games including a group play game. Alternately, gaming machines 1050 may provide a group game as one of a set of multiple primary games selected for play by a random number generator, as described above. Networking components (not shown) facilitate communications across network 1040 between the system server 1010 and game management units 1020 and/or gaming display control computers 1030 that control displays for carousels of gaming machines. Game management units (GMU's) 1020 connect gaming machines to networking components and may be installed in the gaming machine cabinet or external to the gaming machine. The function of the GMU is similar to the function of a network interface card connected to a desktop personal computer (PC) and it may contain tracking software which provides notification to the casino of certain events on a gaming machine 750, including wins. Depending upon the casino management system, payouts on large wins at gaming machines 1050 may be made directly to a player account managed by the host computer; in which case, the player is notified by way of the GMU at gaming machine 1050 that the player's account has been credited.
Some GMU's have much greater capability and can perform such tasks as presenting and playing a game having a group gaming aspect using a display 1025 operatively connected to GMU 1020. In one embodiment, GMU 1020 is a separate component located outside the gaming machine. Alternatively, in another embodiment, the GMU 1020 is located within the gaming machine. Optionally, in an alternative embodiment, one or more gaming machines 1050 connect directly to the network and are not connected to a GMU 1020. Displays related to group games played on gaming machines 1050 or GMU displays 1025 may also be presented on gaming display 1035 by group gaming controller 1030. Group gaming controller is also shown connected to network 1040, through which is may be capable of receiving reconfigured displays for presentation on display 1035. A gaming system of the type described above also allows a plurality of games in accordance with the various embodiments of the invention to be linked under the control of server 1010 for cooperative or competitive play in a particular area, carousel, casino or between casinos located in geographically separate areas.
The various embodiments described above are provided by way of illustration only and should not be construed to limit the claimed invention. For example, it may further be appreciated that each of the games could be operated on a remote host computer such that a player initiates play with the host computer over a network via the player interface and each gaming machine operates the respective gaming and video displays in conjunction with the game whose play is controlled by the remote computer. The top three players in group play mode may not be awarded progressives, but instead compete in a “Tournament of Champions,” or second group play event, with the victor receiving the top-level progressive. In one or more embodiments, all eligible players may be given the option to take a fixed credit amount or a wager multiplier award in lieu of competing in group play. In accordance with another aspect, ineligible players are given an option to “buy” their way into the group play. Similarly, eligible players may be given an option to buy a better starting point value for group play by paying a certain credit amount.
Those skilled in the art will readily recognize various modifications and changes that may be made to the claimed invention without following the example embodiments and applications illustrated and described herein, and without departing from the true spirit and scope of the claimed invention, which is set forth in the following claims.
