       [0002]    A portion of the disclosure of this patent document contains material which is subject to copyright protection. The copyright owner has no objection to the facsimile reproduction by anyone of the patent document or the patent disclosure, as it appears in the Patent and Trademark Office patent files or records, but otherwise reserves all rights of copyright whatsoever. 
       BACKGROUND OF THE INVENTION 
       [0003]    1. Field of the Invention 
         [0004]    This invention relates to gaming systems and to gaming machines used to present gaming results. More particularly, the invention relates to gaming systems, machines and methods which generate a scannable physical game component associable with a game. 
         [0005]    2. Description of the Related Art 
         [0006]    A large number of different gaming machines have been developed to provide various formats and graphic presentations for conducting games and presenting game results. For example, various games may have predetermined designations that may be arranged in a grid or other layout structures. For example, a bingo card may be physically printed on paper or another suitable material, or may be represented by a data structure which defines the various card locations and designations associated with the locations. Various devices and systems have been developed to aid players in playing various wagering games and to enhance player participation in the games, such as through the use of gaming machines and devices. 
         [0007]    In one example, the MegaMania® gaming system offered by Multimedia Games, Inc. comprises a bingo gaming system in which players at different gaming facilities over a large geographic area may participate in bingo games. The players participate in bingo games in the MegaMania® system through electronic player stations that are maintained at various gaming facilities across the United States. Electronic bingo gaming systems and electronic player stations may increase the speed at which certain operations in a bingo game may be performed. However, electronically implemented bingo games have eliminated the use of physical bingo cards in the interest of increasing the speed of play. The elimination of the physical bingo card may represent an unwelcome change to some players who are used to participating in bingo games with a physical bingo card. The elimination of the physical bingo card may also prevent these newer electronic systems from being employed under certain regulatory schemes relating to bingo gaming systems. 
       SUMMARY OF THE INVENTION 
       [0008]    The present invention includes gaming systems, machines and methods in which a player may use a scannable physical gaming component to participate in one or more wagering games played through an electronic player station; wherein the gaming component may be scanned to associate a gaming structure with the player station and used to play one or more games. 
         [0009]    An example method embodying the principles of the invention includes issuing a physical bingo card. This physical bingo card is associated with a layout of spots or locations and bingo designations representing a bingo card. Any layout of locations and the designations contained in those locations to represent a bingo card will be referred to in this disclosure and the accompanying claims as a “bingo structure” in order to avoid confusion with the physical bingo card with which such structures may be associated. A bingo structure associated with a physical bingo card according to the present invention will be referred to herein as a “card bingo structure” to distinguish such bingo structures from those that are not associated with any physical bingo card. 
         [0010]    In addition to issuing the physical bingo card associated with a card bingo structure, an example method according to the present invention includes identifying the physical bingo card and/or the card bingo structure itself through a player station, and collecting a game play request entered from the player station with at least one additional game play request to form a game group. The game play request is associated with the identified card bingo structure and each additional game play request in the game group is associated with a respective additional bingo structure. Once the game group is formed, a bingo game may be conducted between the card bingo structure and each additional bingo structure to identify a bingo game result for the card bingo structure and preferably each additional bingo structure. The method according to the present invention then includes using the player station to display the bingo game result for the card bingo structure. 
         [0011]    An apparatus embodying the principles of the invention includes a physical gaming component issuing station for issuing physical gaming components to players and which are associated or associable with a game structure. A player station may be included in the system together with a game server in communication with the player station. The player station may include a scanner adapted to scan physical gaming components to identify a gaming structure useable in play of one or more games. The player station may respond to a player input at the player station to produce a game play request that is associated with the gaming structure, communicates the game play request to the game server, generates a game result, and communicates the game result to a player at the player station. In one or more examples, the game server collects the game play request produced by the player station with at least one additional game play request to form a game group and conducts a game between respective player stations using the respective gaming structures and determines a winner. 
         [0012]    These and other features of the invention will be apparent from the following description of the preferred embodiments, considered along with the accompanying drawings.

     DESCRIPTION OF PREFERRED EMBODIMENTS 
       [0026]    The present invention will be described below in reference to a particular bingo gaming system in which game play requests or bingo structures are grouped together rapidly for conducting bingo games. This bingo gaming system is described in further detail in pending U.S. patent application Ser. No. 10/456,721, filed Jun. 6, 2003 and entitled “Method, System, and Program Product for Conducting Multiple Concurrent Bingo-Type Games.” The entire content of this application is hereby incorporated by this reference. It will be appreciated, however, that although this illustrated bingo gaming system provides a convenient example of a gaming system in which the present invention may be employed, the invention is by no means limited to use with this type of bingo gaming system. Rather, the present invention of using physical bingo cards in a networked bingo gaming system may be employed in substantially any networked bingo gaming system. In particular, the present invention may be used in a session bingo system in which bingo games are played sequentially throughout various bingo sessions. 
         [0027]      FIG. 1  shows a gaming system  100  including a central game server or game server (CGS)  101  that cooperates with a number of other components to enable bingo players, preferably at many different remote gaming sites, to participate in bingo games. Each gaming site includes a local area server (LAS)  102 , preferably a number of electronic player stations (EPSs)  103 , and preferably a point-of-sale station (POS)  104 . As will be discussed in detail below, in one preferred operation of gaming system  100 , a player at any EPS  103  in the system may participate in a given bingo game with players at any other EPSs  103  in the system. Thus, players at different gaming facilities may be grouped together for a given bingo game administered through system  100 . 
         [0028]    The invention includes an arrangement for grouping players and/or game play requests for the play of a single bingo game to facilitate rapid play. This grouping may include limiting the number of players and/or game play requests included in a bingo game to reduce the time required to play the game. The time between a game play request at one of the EPSs  103  and the return of results to the respective EPS may be reduced sufficiently to allow a great deal of flexibility in how results in the bingo game are displayed to the player. In particular, the bingo game results may be displayed in some manner unrelated to bingo. For example, the bingo game results may be mapped to a display traditionally associated with a reel-type game (slot machine), to a display relating to a card game, or to a display showing a race such as a horse or dog race, for example. Preferred techniques for mapping bingo game results to displays associated with games or contests unrelated to bingo are described in U.S. patent application publication No. 2002-0132661 A1, entitled “Method, Apparatus, and Program Product for Presenting Results in a Bingo-Type Game.” The entire content of this publication is incorporated herein by this reference. 
         [0029]    As will be described further below and in the above-mentioned U.S. application Ser. No. 10/456,721, system  100  may rapidly group players and/or game play requests and starts one game after another so that multiple games may be in play at any given time. That is, once a first group of players or game play requests has been assigned to a bingo game offered through system  100 , the system proceeds to simultaneously administer a bingo game for the first group of players or game play requests and also begins grouping players or game play requests for a next bingo game. In this type of play, system  100  may not necessarily wait for one bingo game to be completed before starting to collect players or game play requests for, and actually beginning play in, the next bingo game. The number of players or game play requests grouped for the play of bingo games according to this mode of play may be limited to reduce the time required for grouping. For example, each bingo game offered through gaming system  100  shown in  FIG. 1  may be limited to between 2 to 20 players or game play requests, with the preferred number for any given game being from 10 to 15. The minimum number of game play requests required to form a game group in this mode of play will be referred to herein as a “quorum” of game play requests. Where system  100  includes numerous EPSs  103  at the various remote locations, on the order of several thousand EPSs for example, hundreds of individual bingo games may be in process at any given time through the gaming system. 
         [0030]    Alternatively, to this multiple simultaneous game mode of play, system  100  may be adapted to conduct bingo games sequentially in bingo sessions. Although this session bingo mode of play may not conduct bingo games based upon any number of game play requests that have been collected, bingo games may still be conducted relatively rapidly to minimize the delay between the time that a player places a card bingo structure in play according to the invention and the time that the player&#39;s EPS  103  receives and displays the result of the game play. 
         [0031]    Regardless of the rapid play facilitated by system  100  and regardless of the manner in which the bingo game results are displayed, the underlying game remains a standard bingo game played in the traditional sequence of play for bingo games. That is, each player obtains or is assigned a bingo structure (either a card bingo structure or a bingo structure not associated with a physical bingo card), all bingo structures in play in the game are daubed or checked for matches with a randomly generated sequence of designations (for example, designations produced in a ball draw or produced by a random number generator), and the first bingo structure in the game to match the sequence of designations to produce the game ending winning pattern wins the bingo game. Additional prizes may be awarded for other patterns that may be produced in the course of the bingo game. The mapping of different prizes to various bingo patterns that may be produced in the course of a bingo game in system  100  may be accomplished as described in U.S. Pat. No. 6,569,017 B2, entitled “Method for Assigning Prizes in Bingo-Type Games” or U.S. patent application publication No. 2004-0048647-A1, entitled “Prize Assignment Method and Program Product for Bingo-Type Games.” The entire content of each of these documents is incorporated herein by this reference. 
         [0032]    According to the present invention, even though gaming system  100  comprises a high-speed bingo gaming system in which players may participate in bingo games through EPSs  103 , a player may still participate in bingo games offered through the system using a physical bingo card. System  100  may be configured so that all players must be issued a physical bingo card and use that card to participate in bingo games offered through the system. Alternatively, system  100  may be configured so that player&#39;s playing with physical bingo cards and players without physical bingo cards may participate in the same bingo games. Yet another implementation of system  100  may group players using physical bingo cards together for producing a game group for a bingo game, and may group players not using physical bingo cards into separate game groups. Example processes associated with grouping players or game play requests and conducting bingo games for those game groups according to the invention will be described below with particular reference to  FIGS. 8 ,  9 , and  10 . 
         [0033]    CGS  101  may comprise a computer system such as the basic system shown in  FIG. 2 . The basic system may include one or more processors  200 , nonvolatile memory  201 , volatile memory  202 , a user interface arrangement  203 , and a communications interface  204 , all connected to a system bus  205 . It will be appreciated that user interface arrangement  203  may include a number of different devices such as a keyboard, a display, and a pointing device such as a mouse or trackball for example, although not shown in  FIG. 2 . Alternatively to the integrated user interface arrangement  203  shown in  FIG. 2 , a user interface for CGS  101  may be provided through a separate computer (not shown) in communication with the CGS. Regardless of the particular configuration for CGS  101 , in one preferred operation of system  100  shown in  FIG. 1 , the CGS functions to group players for participation in bingo games offered through the system, produces or obtains sequences of designations (ball draws, for example) for the play of the bingo games, checks for the results in the bingo games, and communicates the results to LASs  102 . Specific processes performed by CGS  101  to provide these functions will be described below with reference to  FIG. 9 . 
         [0034]    As used in this disclosure, any sequence of designations that may be matched against bingo cards or card representations in the present gaming system will be referred to as a “ball draw” regardless of how the sequence is actually generated. Under this definition, it will be appreciated that a ball draw may be produced by a random number generator, a pseudo random number generator, or any other suitable device or system, and not necessarily a physical ball draw device. 
         [0035]    Each LAS  102  included in system  100  as shown in  FIG. 1  may comprise a computer system having the same basic structure as shown in  FIG. 2 . That is, each LAS  102  may include one or more processors  200 , nonvolatile memory  201 , volatile memory  202 , user interface arrangement  203 , and communications interface  204  all connected to system bus  205 . As with CGS  101 , the user interface for the respective LAS  102  may be provided through a separate computer and communications with the LAS rather than the integrated user interface arrangement  203  shown in  FIG. 2 . Regardless of the specific configuration of the LAS, each LAS serves, in the preferred operation of the system shown in  FIG. 1 , to transfer or relay information from its respective EPSs  103  to CGS  101  and transfer or relay information from the CGS to the LAS&#39;s respective EPSs. Each LAS according to the present invention may also have the ability to group players and actually play bingo games in certain situations. For example, where one LAS  102  serves a large number of EPSs  103 , the LAS may group players or game play requests from its respective EPSs during a time of high player activity, obtain or produce a ball draw, determine results, and return results to the EPSs rather than having the CGS  101  perform these tasks. Also, each LAS  102  shown in  FIG. 1  may be configured to perform the tasks normally performed by CGS  101  in the event the communications link between the respective LAS and CGS is degraded below a certain level or is severed altogether. Specific processes that may be performed by LASs  102  according to the invention will be described below with reference to  FIG. 8 . 
         [0036]      FIG. 3  shows an example of an EPS  103  that may be used in a gaming system embodying the principles of the present invention. The illustrated EPS  103  includes a processor  300 , volatile memory  301 , nonvolatile memory  302 , and a communications interface  303 . The volatile and nonvolatile memory stores computer program code that may be executed by processor  300  to cause the processor to perform or direct the various functions provided by EPS  103 . Communications interface  303  allows communications between EPS  103  and its respective LAS  102  and/or CGS  101 . EPS  103  also includes a user interface arrangement to facilitate player participation in the bingo games offered through gaming system  100  shown in  FIG. 1 , and display results in an exciting and attractive format. This interface includes player controls  304 , a display or touch screen display  305 , a sound system  306 , and perhaps other features  307  such as alarms or special displays or alerting devices. 
         [0037]    The player interface at EPS  103  also includes an arrangement by which information regarding a physical bingo card may be entered into the gaming system. One arrangement may comprise a keypad included in player controls  304  through which a player may manually enter their physical bingo card information at EPS  103 . A keypad for manual bingo card information entry may also be implemented through touch screen  305 . Alternatively or in addition to a manual card information entry device such as a keypad, EPS  103  may include a suitable card reader  308 . Card reader  308  may, for example, comprise a reader for reading information encoded on a magnetic medium (mag stripe) associated with a physical bingo card. Card reader  308  may also be used for reading player-specific information from a player account card or physical bingo card inserted into the reader. Such a card may, for example, include player information or simply a player identifier encoded on the magnetic medium associated with the card. Of course, card reader  308  is not limited to a mag stripe reader or any other type of reader. Rather, card reader  308  may be adapted to read bar codes, a memory device associated with the player card, or data transmitted from a transceiver associated with the card. Card reader  308  may also serve as a scanner according to the present invention. In this alternative, card reader  308  may include or comprise a suitable scanning device such as an optical scanner that scans an object placed in the device and produces a scan output. Card reader  308  may also include a suitable scan controller for applying pattern recognition to the scan output to identify one or more card bingo structures associated with a physical bingo card described below with reference to  FIGS. 6A and 6B . The illustrated EPS  103  also includes a separate device  309  for receiving value and issuing value in the course of play. This device may accept currency, vouchers, or tokens, for example, and also output currency, vouchers, or tokens, and may comprise or include a suitable scanner such as an optical scanner together with its own scan controller. In one preferred form of the invention, device  309  may operate both to receive and issue value and may identify the player&#39;s card bingo structure(s) according to the present invention. That is, device  309  may be adapted to identify and accept currency, either government issued currency or gaming facility issued currency or script, and also identify card bingo structures from a player&#39;s physical bingo card. Alternatively, or in addition to value in/out device  309 , EPSs  103  may read player account information from a player card or player information otherwise input at the EPS, and account for wagers and winnings in the manner set out in U.S. patent application publication No. 2002-0132666 A1, entitled “Distributed Account Based Gaming System,” the entire content of which is incorporated herein by this reference. It will be noted that a physical bingo card according to the present invention may also serve as a player card carrying a player identifier or player account identifier which may be read or entered at EPS  103  and used in the accounting process described in the patent application publication described in the previous sentence. Where an account based arrangement is included in a gaming system embodying the principles of the invention, the accounting functions are preferably performed through an account server implemented through a processor at the respective LAS  102  for the particular gaming facility under the control of account server program code. 
         [0038]      FIG. 3  shows two separate devices  308  and  309  for reading player card information, reading physical bingo card information, and receiving value. It will be appreciated that a single device may be used to perform all of these functions within the scope of the present invention. In particular, a single device may read or scan information from a physical bingo card, and either use that information to obtain card bingo structure information, player information, or player account information, or scan or read multiple cards or media to obtain that information. 
         [0039]      FIG. 4  shows one preferred arrangement for a POS station  104  within the scope of the present invention. POS station  104 , which may be referred to as a physical bingo card issuing station according to the present invention, preferably includes a processor  401 , volatile memory  402 , nonvolatile memory  403 , and a communications interface  404 . The volatile and nonvolatile memory store computer program code that may be executed by processor  401  to cause the processor to perform or direct the various functions provided by POS station  104 . Communications interface  404  allows communications between POS station  104  and its respective LAS  102  and/or CGS  101 . POS station  104  shown in  FIG. 4  also includes a user interface arrangement to facilitate a POS station operator or agent, and/or a player to interface with the gaming system  100  shown in  FIG. 1  for various purposes. This interface includes agent controls  409 , a display or touch screen display  408 , and a card reader/keypad  406 . Controls  409  and display  408  allow a station agent to enter various requests and other information in gaming system  100 . The nature of these requests or information will depend upon the specific features of the gaming system. For example, controls  409  and display  408  may allow a station agent to enter a request to open a player account in gaming system  100  or a request to withdraw cash from the account where the account maintains cash or credit balances for players in the gaming system. Controls  409  and display  408  may also allow a station agent to enter a request for a physical bingo card according to the present invention. Card reader/keypad  406  comprises a device that can read or otherwise identify information from a player card or some device that may be used as a player card such as a physical bingo card according to the present invention. A keypad associated with card reader/keypad  406  allows a player to enter a PIN that may be associated with the player card or player account, or with a physical bingo card according to the present invention. 
         [0040]    POS station  104  further includes a card dispenser  407  and a cash drawer  405 . Cash drawer  405  is included at the illustrated POS station  104  to facilitate the acceptance of cash to open a cash/credit account for the player or to facilitate payments of cash to the player where the player account system provided through gaming system  100  tracks cash or credit balances for the players. Card dispenser  407  dispenses a physical bingo card, such as that shown in  FIGS. 6A and 6B , that may be used by a player to participate in bingo games according to the present invention. Card dispenser  407  comprises a dispenser containing a supply  410  of pre-printed/encoded physical bingo cards or blank cards or substrates that may be used to produce the physical bingo cards. In the pre-printed/encoded card alternative, dispenser  407  merely dispenses one or more of the pre-printed physical bingo cards in response to a command entered at the POS station  104 , and perhaps reads an identifier associated with the dispensed physical bingo card. In the blank card alternative, dispenser  407  may include a printing device  411  to print information regarding one or more bingo structures on the blank card. The information may include a representation of the respective bingo structure and/or an alphanumeric or machine readable identifier that identifies the card and relates the card to a bingo structure definition stored at a suitable component in gaming system  100 . Card dispenser  407  may also include an encoding device  412  for encoding information on the blank cards to be dispensed to the players. For example, the physical bingo card may carry a magnetic medium such as a stripe of magnetic recording material, and the encoding device  412  may include a mag stripe writer capable of writing a card identifier, bingo structure identifier, or other information on the card. Alternatively, the blank cards may carry a minute integrated circuit chip or some other data storage arrangement which may carry information about the dispensed card such as a card identifier, bingo structure identifier, or other information. It will be appreciated that in some preferred forms of the invention, POS station  104  will have the capability of dispensing physical bingo cards to players in an automated fashion through a mechanical dispensing structure included with card dispenser  407 . Alternatively, and particularly where pre-printed and/or pre-encoded cards are to be dispensed, POS station  104  may include an arrangement in which the physical bingo cards are manually removed from the bingo card supply comprising a roll or fan folded group of connected physical bingo cards. 
         [0041]    It will be appreciated that the particular configurations of devices shown in  FIGS. 1 through 4  are shown only for purposes of example. A bingo gaming system according to the present invention may omit some or all of the separate LAS&#39;s  102  at the various gaming facilities so that the EPS&#39;s  103  communicate directly with CGS  101 . Also, various regions or different gaming facilities may be divided up into separate systems each having a respective CGS such as CGS  101 . In these situations the system could be configured such that a single EPS  103  may be serviced by any of the CGSs. Furthermore, a gaming system embodying the principles of the invention may include multiple CGSs rather that a single CGS  101  as shown in  FIG. 1 . A given gaming facility may also include more than one LAS  102  where the gaming facility includes more EPSs  103  than a single LAS  102  may service. 
         [0042]    In the following description of  FIG. 5  and the other block diagrams or process flow charts in this disclosure, it will be appreciated that the references to the physical components are references to the diagrams in  FIGS. 1 through 4  that show those components. The components, such as POS stations  104 , EPSs  103 , LASs  102 , and CGS  101  discussed with reference to the flow charts are generally not shown in the flow charts themselves but are shown particularly in  FIG. 1 . 
         [0043]    Referring now to  FIG. 5 , a method embodying the principles of the invention includes issuing a physical bingo card as indicated at block  501 . This physical bingo card issued to a player in the gaming system is associated with at least one card bingo structure. This card issuing step is performed by a POS station  104  in a preferred form of the invention under the control of card issuing program code to perform the card issuance, card bingo structure printing on the physical bingo card if such printing is done in the given embodiment, and the encoding or printing of information on the physical bingo card to the extent such encoding or printing is done in the given embodiment. It will be appreciated that physical bingo cards according to the present invention need not be issued at a POS station  104  or other similar station. Rather, it is possible for physical bingo cards according to the invention to be issued from an EPS  103  or other player station, or from an unattended kiosk for example. Preprinted physical bingo cards may even be issued manually with no need for any device in communication with the gaming system network, such as system  100  shown in  FIG. 1 . 
         [0044]    A method according to the invention also includes the step of identifying or reading the card bingo structure(s) through a player station (such as EPS  103  in  FIG. 1 ) as indicated at block  502 . This identification step performed through the player station is preferably performed at least in part by a dedicated controller associated with a scanner under the control of scanner program code. Device  308  or device  309  may comprise such a scanner with a dedicated scan controller. Alternatively, device  308  or  309  may simply produce an output signal that is processed by the processor ( 300  in  FIG. 3 ) associated with the respective EPS  103 . 
         [0045]    With the card bingo structure identified or read at an EPS  103 , a game play request entered from the player station, also preferably under the control of the player station program code in response to a player input, is collected with at least one additional game play request to form a first game group as indicated at block  503 . The game play request entered from the EPS  103  is associated with the card bingo structure identified or read at the EPS, and each additional game play request in this collected game group is associated with a respective additional bingo structure. The collection of the game play request together with the additional game play requests may be performed by CGS  101  or some other suitable component in gaming system  100 , such as an LAS  102 , under the control of game server program code executed at that system component. 
         [0046]    As shown at block  504  in  FIG. 5 , the method also includes conducting a bingo game between the card bingo structure and each additional bingo structure to identify a bingo game result for the card bingo structure and preferably the additional bingo structures. The bingo game may be conducted by a suitable processing element using definitions for the bingo structures included in the game group, a ball draw definition, and definitions for the various winning patterns available in the bingo game. This processing element will operate under the control of the game server program code in preferred forms of the invention. 
         [0047]    A method according to the invention further includes displaying the bingo game result for the card bingo structure at the EPS  103  from which the game play request associated with the card bingo structure was entered as indicated at block  505 . This display or communication of the bingo game result is performed at the EPS  103  preferably under the control of the player station program code executed at the player station. 
         [0048]    It will be noted that the additional game play requests grouped with the game play request associated with the card bingo structure to form the game group need not be associated with a physical bingo card or a respective card bingo structure. The gaming system may require that the game group is made up only of game play requests associated with a physical bingo card. Alternatively, game play requests that are not associated with a physical bingo card may be grouped together with those that are associated with such a card. 
         [0049]    In any case, the same system component, such as CGS  101  in  FIG. 1 , collects the game play requests, segregates them as necessary to enforce the rules of the various gaming facilities serviced by the component, and conducts the bingo games to identify the bingo results. It will be appreciated that any game play requests not associated with a physical bingo card may be entered using an EPS  103  process similar to that disclosed at  FIG. 6  of incorporated application Ser. No. 10/456,721, rather than the process described below with reference to  FIG. 7  for game play requests associated with a physical bingo card. Any segregation of game play requests between those associated with physical bingo cards and those that are not may be performed as described in U.S. patent application Ser. No. 10/752,293, filed Jan. 6, 2004, and entitled “Method, System, and Program Product for Grouping Game Players by Class.” The entire content of this prior application is also incorporated herein by this reference. 
         [0050]    The step of issuing the physical bingo card as shown in block  501  may be accomplished in many different ways within the scope of the invention. In one form of the invention, physical bingo cards are pre-printed and/or pre-encoded and are simply dispensed “as is” from a suitable dispenser such as  407  in  FIG. 4 , either an automated dispenser which dispenses a card in response to some control or a manual dispenser which requires the card to be manually removed from the supply of bingo cards. However, some preferred forms of the invention include actually printing and/or encoding information on a substrate to produce a physical bingo card at the time the card is dispensed. The information that may be printed or encoded on the substrate or blank card will be described further with reference to  FIGS. 6A and 6B  below. 
         [0051]    Identifying the card bingo structure at EPS  103  may include several different steps within the scope of the present invention. In one alternative arrangement, the physical bingo card includes one or more printed or encoded card bingo structures and the step of identifying the card bingo structure(s) includes scanning the physical bingo card to produce a scan output, and then applying pattern recognition to the scan output. Applying the pattern recognition process or algorithm results in a scanned card bingo structure that may be associated directly with the game play request entered through the EPS  103 . Alternatively, a verification process may be applied to ensure the scanned card bingo structure correctly reflects the actual bingo structure printed or encoded on the physical bingo card. Such a verification process may involve matching the scanned card bingo structure to a card bingo structure stored in a list of issued card bingo structures. Verification may also involve comparing a physical bingo card identifier read or identified from the physical bingo card with a physical bingo card identifier identified by reading an identifier associated with a card bingo structure matched to the scanned card bingo structure. That is, verification of the scanned card bingo structure may include first matching the scanned card bingo structure to a card bingo structure in a stored list, reading an identifier associated with the card bingo structure in the stored list, and comparing that identifier with an identifier read or determined from the physical bingo card. If these two card bingo structure identifiers do not match, then it is apparent that there has been some error. The error may be in the scanning or pattern recognition applied to identify the card bingo structure. Such an error may require rescanning the card bingo structure or inputting the card bingo structure at the EPS  103  in some alternative or fall back fashion, such as by manual entry for example. Any verification process to verify the card bingo structure identified by the scanner is preferably conducted with a scan verification controller or processor under the control of verification program code. Such a scan verification controller may be implemented with the processor  300  at the EPS or with processor  200  or  201  at the LAS  102  or CGS  101 , or with any other suitable processing device in the system. 
         [0052]    A gaming system according to the present invention may also support a player&#39;s ability to add to or delete card bingo structures associated with the issued physical bingo card. This bingo card modification step is shown at block  506  in  FIG. 5 . The step may be accomplished through a POS station  104  or through an EPS  103  in preferred forms of the invention. The modification process may be initiated with a player/POS agent entering a change request at the EPS/POS station. Although the change request may simply associate a further or replacement card bingo structure with the physical bingo card automatically in response to the change request, the change request preferably initiates a bingo structure selection dialog that allows a player to select a replacement or further card bingo structure from a set of available bingo structures, or even build their own card bingo structure with bingo designations of their own choice at each respective spot in the bingo structure. 
         [0053]    The step of collecting the game play request associated with the physical bingo card and card bingo structure together with the additional game play requests as indicated at block  503  in  FIG. 5  is preferably performed by CGS  101  as will be discussed further below with reference to  FIG. 9 . However, game group collection may also be performed at a respective LAS  102  as will be described with reference to  FIG. 8 . Regardless of how the game group collection is performed or where it is performed, it will be appreciated that where the physical bingo card identified at block  502  is associated with more than one card bingo structure, the game play request entered through the respective EPS  103  must include an indicator as to which card bingo structure is to be in the request, or which bingo structures are to be included in the request. For example, where the bingo games are conducted in fixed bingo sessions, each respective card bingo structure may be associated with a respective bingo game in a sequence of bingo games making up a bingo session. 
         [0054]    The conduct of the bingo game for the game group as shown at block  504  in  FIG. 5  is likewise preferably performed at a central processing device such as CGS  101  or and LAS  102 . Wherever the bingo game is conducted in the gaming system, the results identified in the course of conducting the bingo game are communicated back to the respective EPS  103  so that the EPS may display the results of the bingo game to the player. This communication to facilitate displaying results may or may not include communicating to the EPS  103  the ball draw used for the game. Also, the results of the bingo game may be displayed in a standard bingo format with a representation of a daubed bingo card on the player&#39;s display or in some alternative display such as a reel-type display for example. In yet other alternatives, results may be displayed both as in traditional bingo and in some alternative presentation or display, simultaneously or one after the other. 
         [0055]      FIGS. 6A and 6B  illustrate one preferred form of physical bingo card  601  according to the present invention. This particular physical bingo card  601  includes a first face  602  shown in  FIG. 6A  and an opposite face  603  shown in  FIG. 6B . The card substrate may be formed from any suitable material such as paper or plastic and preferably has a shape similar to a credit card, driver&#39;s license or other identification card, or a ticket such as those commonly issued in automobile parking systems. First face  602  includes representations  605  and  606  of two different card bingo structures. These structures, which are shown diagrammatically in the figures may comprise any suitable structure for use in a bingo game such as the traditional 5 by 5 structure, a 3 by 3 structure, or any other structure of locations through which various location patterns may be identified to distinguish game winners. 
         [0056]    Although two card bingo structures  605  and  606  are shown, any number may be included on the card  601  from none to many. In some forms of the invention, the player must use a different card bingo structure for each game play request. In this form of the invention, card  601  may contain enough bingo structures for a complete bingo session with a large number of individual bingo games. Multiple peel off layers (not shown) may be included on card  601  to facilitate carrying more bingo structures on the card. 
         [0057]    Side  603  of the physical bingo card  601  shown in  FIG. 6B  includes a stripe of magnetic material  608  which can be encoded with a card identifier or with data necessary to actually define the bingo structures  605  and  606  associated with the card. A serial number  609  is also printed on side  603  of card  601 . It will be appreciated that forms of the invention may include different types of data carriers other than magnetic material  608 , such as an integrated circuit chip for example. Also, the data encoded on material  608  may instead be encoded in a bar code printed on the physical bingo card. Furthermore, spare space on side  603  may be printed with additional card bingo structures. 
         [0058]    Preferred forms of the invention maintain a physical bingo card table at a respective suitable memory device at one or more components of the game system. This physical bingo card table may be used to maintain the association between a respective bingo structure and a respective card. One preferred structure for the physical bingo card table includes a number of entries, one entry for each physical bingo card issued in the gaming system. Each entry includes a card identifier unique to the particular physical card and entry, and an identifier or a definition for each card bingo structure associated with the physical card. Each entry may have additional information about the player or the respective physical bingo card. In any case such a table allows the gaming system to identify the card bingo structure(s) associated with a given physical bingo card by doing a look up in the table with the card identifier. Conversely, a physical card with which a card bingo structure is associated may be identified by doing a look up using the card bingo structure identifier or definition. 
         [0059]      FIG. 7  shows a process that may be performed at an EPS  103  according to the invention. After EPS  103  is initialized and activated for use by a player, the process at the EPS includes identifying the card bingo structure(s) as shown at block  701 . This corresponds to the step  501  in the overall process shown in  FIG. 5 . In some forms of the invention, the process at block  701  may include receiving a card bingo structure selection entered through the player station where the physical bingo card is associated with more than one card bingo structure. The process at block  701  in  FIG. 7  may also include a process in which the player may enter a change request to select a different card bingo structure to be associated with their physical bingo card. 
         [0060]    It will be appreciated that the card bingo structure identification step shown at process block  701  in  FIG. 7  may require communications between the respective EPS  103  and its respective LAS  102  or the CGS  101 . In particular, unless the EPS  103  stores a data table of physical bingo card identifiers for physical bingo cards that have been issued in the gaming system, the EPS will have to query such a table stored at some other system component such as an LAS  102  or the CGS  101  in order to verify identified card bingo structure. 
         [0061]    The EPS process shown in  FIG. 7  allows the player to enter a wager or card price for playing a respective card bingo structure in a game offered through an EPS  103 . The wager input is shown at block  702  in  FIG. 7 . This input may be entered through a player control  304  at the respective EPS  103  or a suitable interface associated with screen/touch screen  305  shown in  FIG. 3 . In preferred forms of the invention, the player may choose from a number of different wager levels or card price levels for each card bingo structure the player places in play and these card price levels may be defined in terms of currency, credits, or in some other fashion. 
         [0062]    Once the card bingo structure to be placed in play is identified at EPS  103 , and the price of the card bingo structure or wager is defined, the card bingo structure may be entered in a bingo game administered by the system  100  in which the respective EPS  103  is included. As indicated at process block  704  in  FIG. 7 , EPS  103  may wait for a separate game play input or game play request entered by the player at the EPS, and only then proceed to forward the game play request to the other components of system  100 . In other preferred forms of the invention, a separate input may not be required in order for the player to enter into a bingo game. For example, simply defining the wager at block  702  may automatically enter the identified or designated card bingo structure in a bingo game without any separate game play request, or, where the wager is predefined, the step of identifying the particular card bingo structure may enter the player in a bingo game. 
         [0063]    Once the player has, in one fashion or another, made an input at EPS  103  to enter their card bingo structure(s) in a bingo game administered through the gaming system ( 100  in  FIG. 1 ), the EPS forwards a game play request to the respective LAS  102  as indicated at process block  706  in  FIG. 7 , and preferably drives a display showing some type of entertaining graphics pending the return of the respective result for each player&#39;s card bingo structure placed in play. For example, EPS  103  may be configured to display results associated with the underlying bingo game in terms of reel stop positions for a reel-type gaming machine (slot machine). For this type of result display, the step of driving the display at process block  706  may include showing a number of reels spinning to imitate the spinning reels one would see immediately after activating a traditional reel-type gaming machine. Alternatively, results from the bingo game may be displayed in some other entertaining fashion such as a horse or dog race for example, and the step of driving the display shown at process block  706  in  FIG. 7  may include an initial portion of the race. In yet other forms of the invention, results may be displayed as in a traditional bingo game and the step of driving the display shown at process block  706  in  FIG. 7  may include simply displaying each bingo structure that has been placed in play. Even where the results of the bingo game may be shown with entertaining graphics unrelated to the bingo game, a portion of the display at EPS  103  is preferably devoted to a representation of the card bingo structure in play and ball draw for the bingo game in which the card is entered. 
         [0064]    The nature of the communication forwarding the play request to LAS  102  will depend upon a number of factors. For example, the communication may include an actual bingo structure definition for each card bingo structure placed in play. Alternatively, where bingo structure definition files are available at the various system components as described above, the communication may include a bingo structure identifier for each card bingo structure placed in play and this identifier may be used to locate the actual card definition. In still other forms of the invention, the player&#39;s card bingo structure or structures placed in play from EPS  103  may be known to the LAS or CGS based on an identification of the player at the EPS or in some other way. In this case, the game play request sent to LAS  102  at block  706  in  FIG. 7  may not include even an identifier for the bingo structure(s) in play, but merely some signal for the LAS to place the bingo structure(s) in play for the requesting player. 
         [0065]    Regardless of how EPS  103  drives the display at process block  706  in  FIG. 7 , the EPS preferably receives a ball draw for each game in which the player has been entered and, for each card bingo structure placed in play, a game play result which has been identified at the LAS  102  or CGS  101  as will be described in detail below. The receipt of the ball draw(s) and result is shown at process block  707  in  FIG. 7 . Although the single block  707  is shown for receiving the ball draw for the respective bingo game, it will be appreciated that certain forms of the invention may deliver only a portion of an entire ball draw and then require some player input from EPS  103  in order to receive the remainder of the ball draw. The result received at EPS  103  represents the result of the respective player&#39;s card bingo structure in the bingo game in which the player&#39;s card bingo structure has been entered. As in any bingo game, the result is associated with some pattern and/or sequence of spots on the player&#39;s bingo structure that have been matched by designations in the ball draw. However, it will be appreciated that the result communicated to EPS  103  at process block  707  is preferably some result code that represents the actual bingo result. The ball draw and result may be sent to EPS  103  separately or in a single communication. In either case, the preferred form of the invention displays the ball draw on the display associated with the EPS  103  prior to the time the respective game result is displayed. 
         [0066]    In some preferred forms of the bingo gaming system, the bingo player must claim their bingo prize associated with a winning result. In systems in which the player must claim their prize, the EPS process may include activating a prize claiming or daub input at EPS  103  in the event a game play returns a winning result. This prize claiming or daub input activation is included at process block  707  in  FIG. 7  along with the activation of a timer which sets a time period for the player to actuate the prize claiming or daub input and claim the prize. In a preferred form of the process at EPS  103 , the EPS also produces a display indicating to the player that they must take a particular action to claim their prize, and indicating or counting down the time remaining to claim the prize. This timer or countdown display may be in addition to or in lieu of the display initiated at process block  706 . A countdown timer display according to the invention may be superimposed on the display initiated at process block  706 . 
         [0067]    If the player claims their prize by taking the appropriate action within the set period of time as indicated by decision block  708  in  FIG. 7 , EPS  103  displays the result of the game for the player as indicated at process block  709 , and gaming system awards the prize to the player. In the example described above in which the results may be displayed by reel-type or slot machine graphics, the display at EPS  103  may show reels stopped in particular positions that together correspond to the result achieved by the player in the bingo game. In the example where the results are shown by a horse or dog race, EPS  103  may show a particular horse or dog in a win, place, or show position corresponding to the result the player has achieved in the bingo game. 
         [0068]    In the event the player at EPS  103  does not take the required action to claim the prize within the set period of time, the prize associated with the player&#39;s result in the bingo game may be forfeited as indicated at process block  710 . In the case of a forfeited prize, EPS  103  may also produce a suitable display to indicate to the player that the prize associated with the play in the bingo game has been forfeited. Any forfeited prizes may be collected and applied to a progressive game offered through system  100  or may be collected for use as a charitable contribution. The forfeiture process may include subtracting a prize value from the player&#39;s account. This prize value may have been previously added to the player&#39;s account by system  100  automatically in response to the winning result. 
         [0069]    Whether a prize has been forfeited as shown at process block  710  or has been claimed and the result displayed as shown at process block  709 , the process at EPS  103  may return to wager input and game play input steps  702  and  704  as shown in  FIG. 7 . Alternatively, a number of different options may be provided to the player at EPS  103  to allow the player to choose a different card bingo structure to enter in another bingo game administered through system  100 . 
         [0070]    In some instances, the result from the bingo game may not be associated with any prize. In these instances, the process at EPS  103  may not activate a daub or prize claiming input device, and not wait for an input before displaying the result. Rather, the process at EPS  103  may simply include displaying the non-winning result immediately after receiving the result from LAS  102  without further intervention on the part of the player. 
         [0071]    It will be noted from  FIG. 7  that participation in a bingo game offered through an EPS  103  can be thought of as a three-step process aside from any login step that may be required at the EPS. The first step includes the card bingo structure identification process and the buy-in or wager amount selection process as indicated at process blocks  701  and  702  in  FIG. 7 . In the second step, the player puts the card in play as indicated at process block  704  in  FIG. 7 . In the third step required to participate in a game, the player daubs the card once the bingo numbers have been drawn. This last participation step is indicated by the decision block  708  in  FIG. 7 . The course taken from decision block  708  turns upon whether the prize claiming or daub input has been entered by the player. 
         [0072]    In some forms of the invention, the player&#39;s failure to enter a prize claiming or daub input may not result in the forfeiture of the prize, but rather cause the underlying bingo game to proceed with the ball draw (or additional numbers in the already defined ball draw sequence). In these forms of the invention, a player&#39;s failure to claim the game ending prize causes the underlying bingo game to continue with additional bingo numbers until another game ending winner is produced. This new game ending winner may then be given the opportunity to claim the game ending prize. If the player fails to enter the prize claiming or daub input at this point, the prize may be forfeited or the game may proceed again until another new game ending winner is determined. 
         [0073]    In yet other forms of the invention, the EPS  103  may force the player to take a daubing action in order to proceed on to another game. Also, the daubing step may be defined broadly so as to ensure that a player takes the daubing step to claim their prize. For example, where a player card must be inserted into an EPS  103  in order for a player to participate in a bingo game offered through system  100 , the act of removing the player card may be defined as an act of daubing a card if the EPS  103  is waiting for a daub input from the player. 
         [0074]      FIGS. 8 and 9  may be used to describe one preferred arrangement for cooperation between the LASs  102  and the CGS  101  in system  100  shown in  FIG. 1 , and to describe the processes performed at the LASs  102  and CGS  101  in that arrangement. 
         [0075]    Referring now to  FIG. 8 , one preferred process at each LAS  102  within the scope of the present invention includes at process block  800  receiving a game play request from one of the EPSs  103  serviced by respective LAS and immediately forwarding the game play request to CGS  101  along with information associated with the request such as a bingo structure definition or physical bingo card identifier from which the card definition may be determined. As shown at process block  800 , the LAS process may also include starting a timer on the receipt of the first game play request from a local EPS  103  for a given game. If a timer set at process block  800  times out before CGS  101  returns a ball draw and results for the game play requests which have been collected and forwarded to the CGS as indicated at decision block  801 , LAS  102  may attempt to play the game locally if possible as indicated at process block  802 . A timeout may occur if the communications link has been broken with CGS  101 , or if the communications link has been degraded in some fashion. In this case, it is necessary for LAS  102  to attempt to play games with only local players. Of course, if quorums cannot be produced locally with sufficient speed, LAS  102  may simply notify the EPSs  103  that new games are not presently available, or if the situation is transient, return even money results to the requesting players as discussed further below. 
         [0076]    In situations where no timer is used at LAS  102  or a timeout has not occurred at decision block  801 , the LAS receives a ball draw for the game play requests it has forwarded to CGS  101  along with the results of the game for those play requests/players. The actual communications between LAS  102  and CGS  101  may require that the ball draw is sent in one communication and the results are sent as a separate communication or communications, otherwise both the ball draw information and results for the game may be sent as a single communication. At process block  804 , LAS  102  receives the ball draw and results for the collected number of game play requests that were forwarded to CGS  101 . The process at LAS  102  then proceeds to forward the received ball draw to the EPSs  103  from which the collected game play requests originated, as shown at process block  805 . LAS  102  also forwards the results for the various game play requests, that is, the game results, to the respective EPSs  103 . It will be noted that once a ball draw and results have been received for one group of game play requests that have been forwarded to CGS  101 , the process returns back to process block  800  and continues to receive and forward game play requests for another bingo game as indicated by the line returning from block  804  to a point in the process immediately below the starting point. 
         [0077]      FIG. 9  shows a process at CGS  101  that may be used in connection with the LAS process shown in  FIG. 8 . The process for CGS  101  includes collecting or receiving play requests from the various LASs  102  as shown at process block  900  in  FIG. 9 . CGS  101  also determines if predetermined quorum conditions have been met as shown at process block  901 . A preferred process for this quorum determining step will be described below with reference to  FIG. 10 . If it is determined that conditions for a quorum have not been met at decision block  902 , the process returns back to process block  900  to collect or receive further play requests from LASs  102 . However, if conditions for a quorum have been met as indicated at decision block  902 , CGS  101  collects or segregates the group of game play requests making up the quorum for a bingo game, obtains or produces a ball draw for the game, and determines the results associated with the game by comparing the ball draw with the bingo structure(s) associated with the game play requests which make up the quorum. These functions are shown at process block  904  in  FIG. 9 . In addition to the other steps set out at process block  904 , the process returns back to process block  900  to begin collecting game play requests from the LASs for another bingo game. As shown at process block  905  in  FIG. 9 , CGS  101  also communicates the ball draw and results for a given game to the LASs  102  implicated for the particular quorum that was determined at process block  901 . 
         [0078]      FIG. 10  shows one preferred process for checking for a quorum of game play requests according to the present invention. In this process, checking for a quorum is not conducted according to any time schedule. Rather, the quorum checking process includes receiving or collecting a game play request and then immediately checking for a quorum as indicated at process block  1000 . In one preferred arrangement for implementing the process shown in  FIG. 10 , each received game play request (or data representing the game play request) is stored in a first in/first out queue. Checking for a quorum in this implementation includes checking to see if all or a desired number of queue locations have been allocated, that is, store valid data for a received game play request. Instead of checking to see if the desired number of queue locations have been allocated, the quorum checking process may maintain a counter that provides a value indicating the number of received game play requests that are available for grouping for a bingo game according to the present invention. In this implementation, checking for a quorum includes comparing the number of game play requests received by the counter to see if that number is greater than or equal to some desired minimum number for a bingo game. 
         [0079]    Regardless of how the system checks for a quorum of collected game play requests, if a quorum is not available as indicated at decision block  1001 , the process returns to wait for the next game play request received. However, if it is determined that a quorum is available at decision block  1001 , the process proceeds on to process block  1002  at which the quorum is formed, that is, a group of game play requests are identified for a particular bingo game according to the invention. The process at block  1002  may include reading the data from the queue locations for the game play requests in the game group or quorum and deallocating those queue locations to make them available for additional game play request data. Where a counter is used to track the number of received game play requests, the process at block  1002  may include clearing or resetting the counter to start counting game play requests for the next quorum/bingo game. After process block  1002 , the process returns to wait for additional game play requests or ends if the system is being shut down as indicated at decision block  1004 . 
         [0080]    In operation of the present bingo gaming system, there may be situations in which a quorum suitable for playing a bingo game is not obtained in a reasonable time. As discussed above with reference to block  802  of  FIG. 8 , the system may be configured to return a game play request where a local quorum cannot be produced in a some period of time. Any process for checking for a quorum used in the present system may include a return play request process. Rather than causing the EPSs  103  to ultimately provide some indication to the player that the play request could not be honored, the LAS  102  or CGS  101  as the case may be, may instead send the EPSs  103  from which the game play requests originated a command or signal which causes the EPSs  103  to produce a display showing an even money result. That is, the EPSs  103  may display a result in which the payout is equal to the bet or wager. In this way, the player may not even know that his or her game play request could not be honored and thus they do not feel the frustration that could arise in that situation. Other implementations may return an even money result and cause the EPS  103  to display a message indicating that no game was played to obtain that result. A system embodying the principles of the present invention may display an even money result to a player any time the game play request cannot be honored for whatever reason or just in certain circumstances such as when a quorum cannot be produced in a certain maximum time or when there is some problem with the game play request. The decision to force an even money result at an EPS  103  in lieu of an actual result in a bingo game is preferably made by a system component that identifies the result in the bingo game so as to avoid any conflict with an actual result in a game. However, the present invention may force an even money result display in lieu of an actual result at a component that may not identify the bingo game results. For example, an EPS  103  may be programmed to display an even money result after a certain period of time has elapsed at the EPS after the play request was first communicated. 
         [0081]    Many of the process steps described in  FIGS. 7-10  are preferably performed by processing devices, such as those described in  FIGS. 2 through 4 , under the control of operational program code. For example, first collection program code can be used to collect a first group of game play requests at either an LAS  102  or the CGS  101  as described in relation to process blocks  800 ,  900 , and  1000 . As discussed previously, the game play requests are collected from a number of EPSs  103 . Quorum checking program code can be used to implement process blocks  901  and  1000 , which determine if the first group of game play requests collected by the first collection program code meets the predefined condition for a quorum. If the conditions for a quorum are met, then game program code conducts a bingo-type game with the first group of game play requests as described in relation to process blocks  802 , and  904 . While the game program code is conducting the game with the first group of play requests, second collection program code collects a second group of game play requests from the EPSs  103 . In a preferred embodiment, the game program code can begin conducting a second bingo-type game with the second group of game play requests before the first bingo-type game is completed. 
         [0082]    In one form, the first quorum checking code includes comparison program code for comparing the number of game play requests collected in each respective game group to a minimum number of game play requests, as discussed in  FIG. 10 . Preferably, the comparison code implements process block  1000 , first using counter program code to count the number of game play requests collected in each respective group of game play requests. In various forms, the quorum checking program code also includes allocation program code for checking if a queue location has been allocated, as discussed in relation to process block  1002  and receipt check program code to check for a quorum after each game play request is received, as discussed in relation to process block  1000 . 
         [0083]    As discussed above, the present invention is not limited to a quorum grouping gaming system as described with reference to  FIGS. 7-10 . In particular, the present invention may be implemented in a session bingo gaming system in which bingo games are played in sequence throughout a bingo session. In this session bingo arrangement, the process shown in  FIG. 8  would be modified to eliminate the blocks  800 ,  801 , and  802  as shown. Instead, the respective LAS  102  would simply receive its local game play requests, forward game play information to CGS  101 , and then wait to receive the ball draw and results back from the CGS. The CGS process for the session bingo alternative would also be modified from the illustrated CGS process shown in  FIG. 9 . In particular, the steps shown at blocks  901  and  902  may be eliminated. CGS  101  would simply collect game play requests from the LASs  102  for the period of time in which card bingo structures may be placed in play for the given game and then proceed generally with step  904  in  FIG. 9  upon completion of that period of time. However, the game group for which results are determined at block  904  would not be for a quorum, but for a particular bingo game in a bingo game session. 
         [0084]      FIG. 11  shows an example data structure for defining bingo structures for use in the gaming system shown in  FIG. 1 . The data structure represents a bingo structure definition file  1101  that includes a number of records  1102 , labeled record  0  through record X in the figure. The file may contain a very large number of bingo structure definitions, for example, three hundred thousand or more records  1102 . Bingo structure definition file  1101  will generally also include header information  1104  that may include identifying information for the file and other data related to the bingo structure definition file. The first designation in each record (the designation in the leftmost column in  FIG. 11 ) represents a bingo structure identifier or index that identifies the bingo structure defined by the remainder of the record. The remainder of the record includes a list of designations representing the designations at the various spots in the bingo structure. Using the example 3 by 3 bingo structure  1201  shown in  FIG. 12  for the first bingo structure definition, record  1102  in file  1101 , the record would read 0, 8, 15, 1, 7, 2, 18, 5, 11, 24. In this structure, the 0 represents the bingo structure identifier or index, the designation “8” represents the designation in spot  1  of card  1201 , the designation “15” represents the designation in spot  2  of card  1201 , the designation “1” represents the designation in spot  3  in card  1201 , and so forth for the remainder of the nine spots included in the bingo structure. It will be noted from  FIG. 12  that the spot identifiers are shown as numeric elements in the upper left corner of each spot in the 3 by 3 grid and the larger print number in the middle of each spot represents the bingo designation associated with that spot. 
         [0085]    It will be appreciated that the invention may use bingo structure definition data structures different from those shown for purposes of example in  FIG. 11 . For example, the identifier may be located at any location within the data structure and the spots may not be in the order indicated in  FIG. 11 . 
         [0086]    The process described above at  FIG. 7  relating to the process at an EPS  103  indicates that more than one bingo structure may be placed in a play by a given player. The EPS  103  may be adapted in this alternative to simultaneously display multiple results in one or more bingo games, one result associated with each game play request, that is, each bingo structure placed in play. One arrangement in which multiple bingo results may be displayed simultaneously is described in reference to FIG. 13 of U.S. patent application Ser. No. 10/456,721, previously incorporated herein by reference, and will not be repeated here. The arrangement described in this earlier application utilizes a reel-type or slot machine type display to show the multiple results. Of course results for multiple simultaneous game play may be disclosed to the player at a player station using multiple conventional bingo displays which show the respective bingo structure and the pattern produced by daubing the card against the ball draw. 
         [0087]    It will be noted that in the forms of the invention in which players may place multiple bingo structures in play simultaneously, or the same bingo structure in play multiple times, each bingo structure or instance of the same structure may represent a single game play request. The resulting multiple game play requests made by a player putting multiple bingo structures, or multiple instances of the same bingo structure in play simultaneously may be grouped in a single bingo game according to the invention or may be grouped in multiple different bingo games, depending upon the particular process for grouping game play requests to produce a quorum according to the invention. 
         [0088]    The above described preferred embodiments are intended to illustrate the principles of the invention, but not to limit the scope of the invention. Various other embodiments and modifications to these preferred embodiments may be made by those skilled in the art without departing from the scope of the invention.
