1. A method comprising:
receiving a player identifier;
transmitting the player identifier to a central server;
receiving data corresponding to the player identifier from the central server; and
configuring play of a casino game based on the data.
1. Field of the Invention
The present invention relates to gaming methods and systems. More particularly, the present invention relates to a method and system for adapting casino games to playing preferences.
2. Description of the Related Art
Many casinos offer electronic slot machines, each programmed to play a particular game of chance, such as slots, video poker, or video blackjack. While these games award payouts based upon play results, they are designed to retain, on average, a certain percentage of all money received. This percentage is commonly referred to as the “hold percentage.” Despite the fact that the odds are stacked in favor of slot machines, players still play slot machines not only for their entertainment value, but also in hopes of hitting a large jackpot.
To provide an added incentive to play the slot machines, many casinos offer programs to reward those players who frequently play slot machines. In one such program, a casino accumulates “player reward points” for a player as he spends money on slot machines in that casino. This can be done by networking the slot machines to a central server that stores the points for that player. The casino issues a player tracking card containing a unique player identification number. The player inserts the card into a card reader of a slot machine, which transmits the identification number to the central server. As the player spends money in the slot machine, the server accumulates reward points for that player. After the player accumulates enough points, he can redeem them for, for example, merchandise or apply them against room, food, and beverage charges at the casino hotel.
In many cases, however, these incentives may not be enough to attract casino players to play slot machines. One reason is that players may find it difficult to locate slot machines configured to play the game they prefer. A slot machine is typically programmed to play a single game type (e.g., deuces-wild, video poker). If a player is interested in playing a game other than the game that a particular slot machine is programmed to play, he is forced to wander around the casino until he is able to locate another available slot machine programmed to play the preferred game. In addition, where a group of people visit a casino, members of the group may be forced to split up so that each can find a slot machine programmed to play the game he likes.
Even after players have successfully found slot machines programmed to play the games they like, those slot machines may not be configured to operate in a manner that they like. For example, many slot machines do not permit players to select which language is used, or choose which form of payout (i.e., money, prize, complimentary awards) the player prefers. Thus, locating slot machines configured to players' preferences presents such an imposing task that many players are simply discouraged from even trying and consequently do not play slot machines. Accordingly, conventional slot machines do not satisfy the needs of many players.
To address this shortcoming, some slot machines prompt players at the beginning of every gaming session to select from a menu of games. This, however, requires players to spend some time at the beginning of each and every gaming session choosing their preferred game, which in most cases does not vary from session to session. Many players are unwilling to spend, or uninterested in spending, the time to repeatedly enter the same game selection every time they play. Accordingly, such slot machines are also unsatisfactory.
One embodiment of the present invention provides for receiving a player identifier, transmitting the player identifier to a central server, receiving data corresponding to the player identifier from the central server, and configuring play of a casino game based on the data.
The accompanying drawings are included to provide a further understanding of the invention and, together with the Detailed Description, serve to explain the principles of the invention.
In the drawings:
Embodiments of the present invention allow casino players to customize the play of casino games, including table games and games played at slot machines, according to their playing preferences. Such systems may also tailor the play of casino games for individual players, for example, according to casino preferences. Such systems may eliminate the need for players to wander around a casino to locate a slot machine, slot machine game, or table game configured in the manner they prefer. Moreover, these systems allow casino games to be adapted to maintain the interest of the player.
Embodiments of the invention allow casino players to set player parameters easily, such as game type, language, and payout options, to preselected player preferences. In such systems, one or more casino devices (e.g., slot machines, other game devices, card readers, personal digital assistants (PDAs), data entry terminals, data display terminals) are networked to one or more central servers that store information about player preferences. As is known in the art, a central server comprises a computer or similar device that responds to requests from clients, such as casino devices. Such requests may be for data, programs, computations, processing or other resources the clients request. As is also known in the art, a central server may comprise a plurality of computers that work together and present the appearance of a single server to a client.
After a player provides a player identifier to the networked casino device (e.g., by inserting a player tracking card into a card reader device of a slot machine), the casino device transmits the player's identification number to the central server. The central server accesses and transmits player preferences associated with the received identification number to a casino device to configure play of a casino game for the player. The central server may also access and transmit other data associated with the received identification number, as described below.
The casino device receiving the player preferences does not have to be the same casino device that transmitted the player's identification number to the central server. The casino device receives the player preferences from the central server and configures the game to operate according to the received player preferences. Alternatively or in addition, casino personnel (e.g., table game dealer, slot host) may use the received player preferences to configure play of a casino game for the player. According to another alternative embodiment, the server configures the game to operate according to player preferences without transmitting the player preferences to the casino device.
Embodiments of the invention also allow casino devices to modify casino parameters, such as hold percentage, complimentary award rate, and game eligibility, to casino preferences according to the performance of casino players to enhance their play experience. The networked casino device transmits to the central server a player's identification number and performance data for a casino player. The central server receives the player identification number and performance data, determines appropriate casino preferences, and transmits the casino preferences to a casino device to configure play of a casino game for the player. The casino device receiving the player preferences does not have to be the same casino device that transmitted the player's identification number to the central server. The casino device receives the casino preferences from the central server and configures the game to operate according to the received casino preferences. Alternatively, casino personnel (e.g., table game dealer, slot host) may use the received player preferences to configure play of a casino game for the player. According to another alternative embodiment, the server configures the game to operate according to casino preferences without transmitting the casino preferences to the casino device.
A gaming system consistent with one embodiment of the present invention is adaptable to playing preferences and comprises a slot machine for allowing a player to bet on pseudo-randomized events and a central server. The slot machine includes a device for receiving preference data representing a preferred operation of the slot machine and a device for programming the slot machine to operate according to the received preference data. The server includes a device for storing a collection of data representing various operations of the slot machine and a device for selectively transmitting a portion of the stored collection of data to the slot machine as preference data. The server may also include a device for receiving data indicating a preferred operation of a slot machine.
In one embodiment, a server for configuring a slot machine to playing preferences comprises a device for storing a collection of data representing various operations of the slot machine and a device for selectively transmitting a portion of the stored collection of data to the slot machine as preference data. The server may also include a device for receiving data indicating a preferred operation of a slot machine.
In one embodiment, a game machine adaptable to playing preferences for allowing a player to bet on pseudo-randomized events controlled by the game machine comprises a device for receiving preference data representing a preferred operation of the game machine from an electronic storage medium and a device for configuring the game machine to operate according to the received preference data.
Network server 110 may comprise conventional server computer hardware, such as an RS 6000 manufactured by IBM Corp. Server 110 executes software instructing the hardware to execute unique functions and operations in accordance with the principles of the invention. Slot machine 120 may comprise a conventional slot machine modified to carry out the functions and operations described below.
Network server 110 and slot machine 120 transmit digitally encoded data and messages to one another. The transmitted data preferably represents player name and identification number (or other player identifier), play results, authenticated player identification, preferences selections, and preferences data. Those having ordinary skill in the art will appreciate that the transmitted data need not be limited to the above. For example, transmitted data may relate to the time, to a message, to information about the casino, or to information about a hotel associated with the casino.
The terms “player identification number” and “player identifier” as used in this application refer to any identifier that may identify a player to the system 100. The player identifier does not necessarily have to be a number.
The communications link between server 110 and slot machine 120 preferably comprises a cable on which electronic signals can propagate. Alternatively, however, the communications link may comprise other conventional communications links, such as over-the-air broadcast transmission or any wireless transmission means.
Network server 110 executes one or more programs to perform the functions and operations described below and stores one or more databases of data relating to those functions and operations. These databases include player database 214, player preferences database 216, and casino preference database 218. The programs (not shown) are preferably stored in storage device 210 and executed by CPU 200.
Transaction processor 212 accesses information to and from the databases in data storage device 210. Transaction processor 212 may comprise a separate, conventional CPU/microprocessor, as shown in
Player database 214 provides a repository of information on players. Players preferably receive casino player tracking cards from a casino by registering with the casino's card issuing authority. Alternatively, players may provide information to the casino without registering for or receiving a casino player tracking card. For example, a player at a slot machine may input information to the slot machine 120, as discussed further below, without registering for a player tracking card.
Player preferences database 216 provides a table of information on player preferences indexed by player identification number. As shown in
Player preferences do not have to be entered through a slot machine. According to alternative embodiments of the present invention, selected preferences may be transmitted by the player to slot machine 120 or network server 110 via the Internet (e.g., by using the keyboard of a personal computer to input preferences into a form displayed at a web site), a telephone call (e.g., via an interactive voice response unit (IVRU)), or via a handheld device (e.g., a personal digital assistant (PDA)).
A player's preferences may also be determined by the slot machine 120 or network server 110 based on selections made by the player during game play. For example, the network server 110 may store an indication of the configuration used by the player the last time he played, or may determine a player's preferences based on the settings that the player has selected most often or on the games most often played.
Casino preferences database 218 contains a table of information on casino preferences indexed by player identification number. Casino preferences reflect certain parameters that casinos can adjust according to certain criteria, such as skill level or playing frequency, to maintain the interest of its players.
Complimentary rate indicates how often players should receive complimentary amenities. Complimentary award limit indicates the maximum number or volume of complimentary amenities each player should receive in a given time period (e.g., per night).
Game eligibility indicates whether each player is qualified to play certain games. For example, a casino may reserve particular machines for its most frequent players. Casino preferences database 218 would indicate which players qualify for such games.
The last field labeled “other” contains information representing other variables that can be modified to uniquely customize a game so that the player maintains interest. For example, this field may indicate that the number of player award points accumulated during a certain period of time should be increased by a multiplier to stimulate interest in the player's continued play of the slot machine. Alternatively, the “other” field may contain a stored player gambling history to develop a customized casino preferences and complimentary award program. Such a program would typically be developed to maintain a player's interest in continuing to play a game at a time when the history indicates he may otherwise stop. For example, where the player gambling history indicates that a player typically stops after losing a certain dollar value, the preferences and award program may be designed to improve his odds of winning as he approaches his typical stop value. In alternative embodiments, casino preferences database 218 may include more or fewer fields.
With respect to gaming operations, slot machine 120 operates in a conventional manner. The player starts the machine by inserting a coin, or sing electronic credit, and pressing starting controller 374. Under control of a program stored, for example, in storage device 320 or ROM 340, CPU 310 initiates random number generator 372 to generate a number. CPU 310 looks up the generated random number in stored probability table 322 and finds the corresponding outcome. Based on the identified outcome, CPU 310 locates the appropriate payout in the stored payout table 324. CPU 310 also directs reel controller 330 to spin reels 332, 334, 336 and to stop them at a point when they display a combination of symbols corresponding to the generated outcome. When the player wins, the machine stores the credits in RAM 342 and displays them in video display area 346.
Hopper controller 352 is connected to hopper 354 for managing the flow of coins. When the player requests to cash out by pushing a button on slot machine 120, CPU 310 checks RAM 342 to see if the player has any credits and, if so, signals hopper controller 352 to release an appropriate number of coins into a payout tray.
In alternative embodiments, slot machine 120 does not include reel controller 330, and reels 332, 334, 336. Instead, video display area 346 graphically displays simulated representations of objects contained in the selected game, such as graphical reels or playing cards. These representations preferably animated or displayed to simulate playing of the selected game.
Player card tracking device 360 includes display 362 and card reader 364. Players insert player tracking cards into card reader 364. Tracking cards can be plastic cards with magnetic strips electronically storing respective player identification numbers. For example, a hotel key card or a credit card may be used as a tracking card. Display 362 displays information concerning the use of tracking device 360. Display 362 may be a touch screen display for receiving signals from the player concerning his selection of the options.
Alternatively, machine 120 or device 360 may include one or more separate input buttons (not shown) for the players to select the options and provide other input such as a PIN (personal identification number) or other player identifier that identifies a player. In other embodiments, slot machine 120 recognizes the identity of players through player identification devices other than player card tracking device 360, thereby eliminating the need for players to identify themselves using player identification cards. For example, slot machine 120 could include a keypad, at which players enter either their player identification numbers or their names along with a secured password. Slot machine 120 could also include a device for measuring player biometrics (i.e., facial features, fingerprint, voice, or retinal scan) to identify players.
Alternatively, preferences may be selected by the player issuing voice commands into a microphone (not shown) connected to slot machine 120 or inputting his preferences via a keypad (not shown) connected to slot machine 120.
Alternatively, machine 120 or device 360 may include one or more receivers (not shown) capable of receiving a signal that identifies a player, and also capable of receiving signals from the player concerning his selection of the options. For example, slot machine 120 could also include a device for receiving such signals from a communication device (not shown) such as a cellular telephone, handheld display device, or personal digital assistant (PDA).
Commercially available player card tracking devices include, for example, the Mastercom device available from Bally Manufacturing. (See, for example, U.S. Pat. No. 5,429,361 to Raven et al.). Such player tracking devices include a magnetic card reader and a numeric keypad for entry of player information.
Preferences selection button 370 allows a player to initiate selection of player preferences and to select player preferences displayed on video display area 346. Button 370 may comprise a conventional input device, such as a keyboard or dedicated buttons marked with appropriate labels.
Game parameter database 326 provides a table of information on game parameters that can be set in slot machine 120. Game parameters generally relate to those parameters that players may want to customize in their game playing.
Casino parameters database 328 provides a table of information on casino parameters that can be set in slot machine 120. Casino parameters generally relate to those parameters affecting awarding of payouts from slot machine 120.
Operation of the System
The operation of system 100 will be described with respect to two different aspects. First, system 100 operates to adapt slot machine 120 to player preferences. Second, system 100 operates to adapt slot machine 120 to casino preferences. These operations may occur concurrently to adapt slot machine 120 to both player and casino preferences.
Adapting to Player Preferences
Before slot machine 120 can adapt to player preferences, the player must enter his preferences into system 100.
Once a player has selected his preferences, he may later retrieve them for configuring slot machine 120.
Next, server 110 accesses the player database 214 (step 1015) and determines whether the player has previously established player preferences (step 1020). If not, server 110 informs slot machine 120, which retrieves game default values stored in game parameter database (step 1025). If the player does have established preferences (step 1020), network server 110 accesses player preferences database 216 and transmits the preferences data corresponding to that player's identification number to slot machine 120 (step 1030).
In one embodiment, server 110 transmits data actually representing the player preferences. In an alternative embodiment, server 110 transmits codes representing the player preferences, in which case slot machine 120 translates the received codes into player preferences using game parameter database 326. In another alternative embodiment, server 110 transmits a signal generated by the server 110 based on the player preferences. The signal is operative to configure play of the slot machine 120 according to the player preferences.
Slot machine 120 then queries the player whether to use previously established player preferences (step 1035). If not, slot machine 120 uses game default values stored in game parameter database 326 (step 1025). If the player indicates a desire to use his player preferences, slot machine 120 overrides the game default values and configures the game in slot machine 120 to match the player preferences (step 1040). Alternatively, slot machine 120 configures the game to the player's preferences without any input from the player. Alternatively, as described above, play of a game at slot machine 120 may be configured by a signal received from server 110.
Adapting to Casino Preferences
In one embodiment, server 110 transmits data representing the casino preferences. In another embodiment, server 110 transmits codes representing the casino preferences, in which case slot machine 120 translates the codes into the casino preferences using casino parameter database 328. In another alternative embodiment, server 110 transmits a signal generated by the server 110 based on the casino preferences. The signal is operative to configure play of the slot machine 120 according to the casino preferences.
Slot machine 120 configures the game to match the received casino preferences (step 1135). Alternatively, as described above, play of the game at slot machine 120 may be configured by a signal received from server 110.
Server 110 preferably establishes casino preferences by applying the received play results to predetermined rules. These rules may consider, for example, the skill of the player or the amount of money spent before the player quits. These rules are preferably designed to adjust casino parameters to stimulate the player's interest in continuing to play slot machine 120. Server 110 also calculates and stores any complimentary awards due the player.
Slot machine 120 next configures the game to match the received casino preferences (step 1155), and determines whether the player has removed his card (step 1160). If not, steps 1140-1155 are repeated. If the player has removed his card, slot machine 120 configures the game to match casino default values (step 1165).
Although the system has been described as one or more slot machines networked to a central server, the invention applies to other games, casino games, and gaming environments. For example, the invention can be applied to table games, such as blackjack and craps. Players insert their player tracking cards into card readers corresponding to seats around, for example, a blackjack table. As discussed above, alternative means may be used to identify the players. The central server could access player preferences data and casino preferences data for the players, and transmit that data to a data terminal or other casino device located at the dealer. The dealer could then modify the game or award payouts according to the preferences.
The invention also could apply to other environments or systems involving one or more data terminals networked to a central server to configure the terminals to identifiable users or operators. For example, the invention could be applied to networked video game systems, systems with point-of-sale terminals, and automatic teller machines (ATM). This eliminates the need for users or operators to manually enter information during each and every session to configure the terminals.
Further, player preferences data may be stored entirely on the player tracking card, rather than a central server. In such an embodiment, a machine reads the player preferences data from a received player tracking card and stores updated player preferences data on the card. In this way, player preferences move from machine to machine with the player's use of the card. Casino preferences may be added to the card periodically by, for example, temporarily providing the card to casino personnel for this purpose.
Alternative identifiers for identifying a player include: a physical characteristic (e.g., using a video camera to determine identity based on, for example, face, height, and/or stride), a credit card number, a smart card, a cell phone signal, an signal transmitted from a PDA or handheld device, a bar code, a serial number of currency used, a telephone number, a player-selected number or symbol, a room key and a room number.
As an alternative (or in addition to) storing multiple types of games at each slot machine or other casino device, multiple types of games could be stored at the network server. For example, when a different game is needed at a slot machine, based on stored player preferences or on selection by the player, the network server could transmit (or otherwise distribute) the game to the slot machine. Similarly, fonts, languages, pay tables and other data typically stored at each networked casino device could be stored at the network server and distributed as needed. By determining and distributing the necessary data to the slot machine in accordance with player preferences and/or casino preferences, the server could configure play of a casino game at the slot machine.
When a player terminates a game session (e.g., withdraws his player tracking identification card), the network server 110 may store an indication of the player's game progress. For example, in addition to storing an indication of the game configuration at the time play was terminated, the network server 110 may also store an indication of how many cherry symbols the player had collected, the displayed hand, or the number of levels of the game completed by the player. When the player begins game play again, the network server 110 may thus provide the player the option of continuing play of the game as if it had not been interrupted.
The casino device receiving the indication of playing preferences from the central server does not have to be the same casino device that the player used to identify himself to the system. For example, in the blackjack table game embodiment described above, the player may insert his player tracking card into a card reader at his seat, but the preference data corresponding to the player may be transmitted by the server to a data terminal viewed by the dealer. According to another example, the player may identify himself to the system upon checking into a hotel associated with the casino, or upon providing his identification information to a device on the slot floor. In response, an available slot machine is configured according to his preferences, and the player is then directed to the available slot machine.
It will be apparent to those skilled in the art that various modifications and variations can be made in the method and system of the present invention without departing from the spirit or scope of the invention. For example, the databases described above may reside in one or more databases stored in the data storage devices of either slot machine 120 or network server 110. The present invention covers the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
