Illuminated player tracking card for a gaming apparatus

ILLUMINATED PLAYER TRACKING CARD FOR A GAMING APPARATUS

Background of the Invention The present invention is directed to an illuminated player tracking card for use with a lottery or gaming apparatus, which could be either an individual gaming apparatus or a gaming system having a plurality of gaming apparatuses.

A gaming apparatus allows a customer of a casino or other facility to play one or more games, such as poker, blackjack, slots, keno, and bingo. A customer typically approaches a gaming unit, and selects a desired game from the games offered on the gaming unit. Upon selection of the desired game, that game appears on the gaming unit, at which time the customer is allowed to play.

During play, the customer places a bet and proceeds with the selected game. For example, where the customer is playing slots, a lever may be pulled to spin the reels. The reels then stop on various symbols, which determines the customer's payout for that spin, after which the customer may place another wager and proceed as discussed above. Where the customer has selected to play blackjack or poker, the player may hit a "deal card" button to deal out the cards for the respective card game. The customer may alter his wager during, the particular hand based on which cards are dealt, and in some card games, replace cards, or continue to request cards.

After all replacements and/or requests are made, a payout is determined, and the player may continue by placing another wager and playing a new hand.

When a player uses the lottery or gaming apparatus, it is advantageous for personnel of the casino or other facility to be able to observe the status of the gaming apparatus, the status of the game that is being played by the player, and perhaps obtain information about the player. It is advantageous to obtain this information by viewing a pattern of illumination of a plurality of lights. It is further advantageous to use the illumination of the lights to attract players to a particular gaming apparatus. Previous attempts to accomplish this have resulted in locating the lights so that they are viewed directly from the gaming apparatus. This approach however has proven to have limited success in attracting and encouraging players to use particular gaming apparatuses.

Summary of the Invention The invention is directed to an apparatus that may comprise a gaming apparatus with a housing and a display unit that is associated with the housing and is capable of generating video images. The gaming apparatus also includes a value input device that is capable of allowing the player to deposit a medium of value. Additionally, the gaming_. apparatus may comprise a card reader may having a light generating source that is associated with the card reader and a data reading apparatus that is also associated with the card reader. The gaming apparatus may also comprise a controller, wherein the controller is operatively coupled to the display unit, the value input device, and the card reader. The controller may have a processor and a memory operatively coupled to the processor. Additionally, the controller may be programmed to allow a person to make a wager and to cause a video image to be generated on the display unit after the value input device detects deposit of value by the person.

The video image may represent a game selected from the group of games consisting of video poker, video blackjack, video slots, video keno and video bingo, in which case the video image may comprise an image of at least five playing cards if the game comprises video poker. Likewise, the video image may comprise an image of a plurality of playing cards if the game comprises video blackjack. If the game selected by the player is video slots, the video image may comprise an image of a plurality of simulated slot machine reels. The video image may comprise an image of a plurality of keno numbers if the game comprises video keno, or the video image may comprise an image of a bingo grid if the game comprises video bingo. The controller may also be programmed to determine an outcome of the game represented by the video image and a value payout associated with the outcome of the game. The apparatus may also include a player tracking card that may be disposed in the card reader. The player tracking card may comprise a data storage device that stores data representing the identification of a player. Additionally, the player tracking card may comprise a first card surface, a second card surface, and a light transmissive body portion extending between the first card surface and the second card surface. The player tracking card may be positioned in a card illumination position wherein the first card surface is disposed in the card reader so that the first card surface is positioned adjacent the light generating source associated with the card reader, and the second card surface of the player tracking card remains visible outside the card reader. Also, when said player tracking card is in the card illumination position, light generated by the light generating source may be transmitted into the first card surface of the player tracking card and then transmitted through the light transmissive body portion of the player tracking card so that light may be visible to the user through the second card surface. The features and advantages of the present invention will be apparent to those of ordinary skill in the art in view of the detailed description of various embodiments, which is made with reference to the drawings, a brief description of which is provided below.

The data link 24 may provided as a dedicated hardwired link or a wireless link. Although the data link 24 is shown as a single data link 24, the data link 24 may comprise multiple data links.

Fig. 2 is a perspective view of one possible embodiment of one or more of the gaming units 20. Although the following description addresses the design of the gaming units 20, it should be understood that the gaming units 30 may have the same design as the gaming units 20 described below. It should be understood that the design of one or more of the gaming units 20 may be different than the design of other gaming units 20, and that the design of one or more of the gaming units 30 may be different than the design of other gaming units 30. Each gaming unit 20 may be any type of gaming unit and may have various different structures and methods of operation. For exemplary purposes, various designs of the gaming units 20 are described below, but it should be understood that numerous other designs may be utilized.

Referring to Fig. 2, the gaming unit 20 may include a housing or cabinet 50 and one or more input devices, which may include a coin slot or acceptor 52, a paper currency acceptor 54, a ticket reader/printer 56 and a card reader 58, which may be used for several purposes, as will be described in detail below. A value input device may include any device that can accept value from a customer. As used herein, the term "value" may encompass gaming tokens, coins, paper currency, ticket vouchers, credit or debit cards, and any other object representative of value. If provided on the gaming unit 20, the ticket reader /printer 56 may be used to read and/or print or otherwise encode ticket vouchers 60. The ticket vouchers 60 may be composed of paper or another printable or encodable material and may have one or more of the following informational items or gaming data printed or encoded thereon: the casino name, the type of ticket voucher, a validation number, a bar code with control and/or security data, the date and time of issuance of the ticket voucher, redemption instructions and restrictions, a description of an award, and any other information that may be necessary or desirable. Different types of ticket vouchers 60 could be used, such as bonus ticket vouchers, cash-redemption ticket vouchers, casino chip ticket vouchers, extra game play ticket vouchers, merchandise ticket vouchers, restaurant ticket vouchers, show ticket vouchers, etc. The ticket vouchers 60 could be printed with an optically readable material such as ink, or data on the ticket vouchers 60 could be magnetically encoded. The ticket reader/printer 56 may be provided with the ability to both read and print ticket vouchers 60, or it may be provided with the ability to only read or only print or encode ticket vouchers

60. In the latter case, for example, some of the gaming units 20 may have ticket printers 56 that may be used to print ticket vouchers 60, which could then be used by a player in other gaming units 20 that have ticket readers 56.

If provided, the card reader 58 may include any type of card reading device, such as a magnetic card reader or an optical card reader, and may be used to read data from a card offered by a player, such as a credit card or a player tracking card 59. If provided for player tracking purposes, the card reader 58 may be used to read gaming data from, and/or write gaming data to, player tracking cards that are capable of storing data representing the identity of a player, the identity of a casino, the player's gaming habits, etc. The card reader 58 may also include additional components that are described in conjunction with Fig. 4.

The gaming unit 20 may include one or more audio speakers 62, a coin payout tray 64, an input control panel 66, and a color video display unit 70 for displaying images relating to the game or games provided by the gaming unit 20. The audio speakers 62 may generate audio representing sounds such as the noise of spinning slot machine reels, a dealer's voice, music, announcements or any other audio related to a casino game. The input control panel 66 may be provided with a plurality of pushbuttons or touch-sensitive areas that may be pressed by a player to select games, make wagers, make gaming decisions, etc. Fig. 2A illustrates one possible embodiment of the control panel 66, which may be used where the gaming unit 20 is a slot machine having a plurality of mechanical or "virtual" reels. Referring to Fig. 2A, the control panel 66 may include a "See Pays" button 72 that, when activated, causes the display unit 70 to generate one or more display screens showing the odds or payout information for the game or games provided by the gaming unit 20. As used herein, the term

"button" is intended to encompass any device that allows a player to make an input, such as an input device that must be depressed to make an input selection or a display area that a player may simply touch. The control panel 66 may include a "Cash Out" button 74 that may be activated when a player decides to terminate play on the gaming unit 20, in which case the gaming unit 20 may return value to the player, such as: by returning a number of coins to the player via the payout tray 64, printing a ticket 60, or writing information to a card 58.

If the gaming unit 20 provides a slots game having a plurality of reels and a plurality of paylines which define winning combinations of reel symbols, the control panel 66 may be provided with a plurality of selection buttons 76, each of which allows the player to select a different number of paylines prior to spinning the reels. For example, five buttons 76 may be provided, each of which may allow a player to select one, three, five, seven or nine paylines.

If the gaming unit 20 provides a slots game having a plurality of reels, the control panel 66 may be provided with a plurality of selection buttons 78 each of which allows a player to specify a wager amount for each payline selected. For example, if the smallest wager accepted by the gaming unit 20 is a quarter ($0.25), the gaming unit 20 may be provided with five selection buttons 78, each of which may allow a player to select one, two, three, four or five quarters to wager for each payline selected. In that case, if a player were to activate the "5" button 76 (meaning that five paylines were to be played on the next spin of the reels) and then activate the "3" button 78 (meaning that three coins per payline were to be wagered), the total wager would be $3.75 (assuming the minimum bet was $0.25). The control panel 66 may include a "Max Bet" button 80 to allow a player to make the maximum wager allowable for a game. In the above example, where up to nine paylines were provided and up to five quarters could be wagered for each payline selected, the maximum wager would be 45 quarters, or $11.25. The control panel 66 may include a spin button 82 to allow the player to initiate spinning of the reels of a slots game after a wager has been made. In Fig. 2A, a rectangle is shown around the buttons 72, 74, 76, 78, 80, 82.

It should be understood that the rectangle simply designates, for ease of reference, an area in which the buttons 72, 74, 76, 78, 80, 82 may be located. Consequently, the term "control panel" should not be construed to imply that a panel or plate separate from the housing 50 of the gaming unit 20 is required, and the term "control panel" may encompass a plurality or grouping of player activatable buttons.

Although one possible control panel 66 is described above, it should be understood that different buttons could be utilized in the control panel 66, and that the particular buttons used may depend on the game or games that could be played on the gaming unit 20. Although the control panel 66 is shown to be separate from the display unit 70, it should be understood that the control panel 66 could be generated by the display unit 70. In that case, each of the buttons of the control panel 66 could be a colored area generated by the display unit 70, and some type of

1 mechanism may be associated with the display unit 70 to detect when each of the buttons was touched, such as a touch-sensitive screen.

The apparatus 20 may also include an energy transfer apparatus 84, a light generating source 86, a data reading apparatus 88, and a power source 90 (see Fig. 3)- Gaming Unit Electronics

Fig. 3 is a block diagram of a number of components that may be incorporated in the gaming unit 20. Referring to Fig. 3, the gaming unit 20 may include a controller 100 that may comprise a program memory 102, a microcontroller or microprocessor (MP) 104, a random-access memory (RAM) 106 and an input/output (I/O) circuit 108, all of which may be interconnected via an address/data bus 110. It should be appreciated that although only one microprocessor 104 is shown, the controller 100 may include multiple microprocessors 104. Similarly, the memory of the controller 100 may include multiple RAMs 106 and multiple program memories 102. Although the I/O circuit

108 is shown as a single block, it should be appreciated that the I/O circuit 108 may include a number of different types of I/O circuits. The RAM(s) 106 and program memories 102 may be implemented as semiconductor memories, magnetically readable memories, and/or optically readable memories, for example. Fig. 3 illustrates that the control panel 66, the coin acceptor 52, the bill acceptor 54, the ticket reader/printer 56, the card reader 58, an energy transfer apparatus 84, a light generating source 86, and a data reading apparatus 88, may be operatively coupled to the I/O circuit 108, each of those components being so coupled by either a unidirectional or bidirectional, single-line or multiple-line data link, which may depend on the design of the component that is used. The speaker(s) 62 may be operatively coupled to a sound circuit 112, that may comprise a voice- and sound-synthesis circuit or that may comprise a driver circuit. The sound-generating circuit 112 may be coupled to the I/O circuit 108. A power source 90 may be utilized to provide electrical power for the controller 100 and the interconnected components 52, 54, 56, 58, 62, 66, 84, 86, 88, and 112.

As shown in Fig. 3, the components 52, 54, 56, 58, 66, 84, 86, 88, and 112 may be connected to the I/O circuit 108 via a respective direct line or conductor. Different connection schemes could be used. For example, one or more of the components shown in Fig. 3 may be connected to the I/O circuit 108 via a common bus or other data link that is shared by a number of components. Furthermore, some of the components may be directly connected to the microprocessor 104 without passing through the I/O circuit 108.

Fig. 4 illustrates schematically an embodiment of a player tracking card 59 disposed in a card reader 58. As will be discussed in more detail below, the player tracking card 59 is positioned in a card illumination position. The card reader 58 may include a mounting plate 113 to assist in securing the card reader 58 to the housing 50 of the gaming apparatus 20. The card reader 58 may also include a chassis 114 which may comprise a first side rail 116, a second side rail 118, and a back structure 120. The card reader 58 of Fig. 4 may also include a number of light generating sources 122. The light generating sources 122 shown in Fig. 4 are fixed to the back structure 122 of the chassis 114, however the light generating sources 122 may also be secured directly to the housing 50 of the gaming apparatus 20 or any other structure within the housing 50 that is separate from the card reader 58. The light generating sources 122 may comprise LEDs, OLEDs, incandescent lamps, fluorescent lights, or any other device capable of generating light. If a plurality of the light generating sources 122 are used, they may produce light that is uniform in color or they may produce a plurality of different colors. The light generating sources 122 may be connected to the controller 100 through a plurality of corresponding conductors 124 to control the intensity and pattern of illumination of the light generating sources 122. The conductors 124 may be connected to a modular connector 126 for ease of installation into the gaming apparatus 20.

The player tracking card 59 may be positioned in the card illumination position when the card 59 is disposed in the card reader and a first card surface 127 is adjacent the light generating sources 122. In the embodiment shown in Fig. 4, the player tracking card 59 may rest on the side rails 116 and 118 and the first card surface 127 may abut the back structure 120 of the chassis 114 when the player tracking card 59 is in the card illumination position. Thus, when the player tracking card 59 is in the card illumination position, light generated by the light generating sources 122 is transmitted into the first card surface 127 of the player tracking card

59. A data reading apparatus 128 may also be included in the gaming apparatus to read data from the player tracking card 59 that is disposed in the card reader 58. The data reading apparatus 128 may be attached to the chassis 114 so that it is in close proximity to the player tracking card 59 when the player tracking card 59 is disposed in the card reader 58 and in the card illumination position. The data reading apparatus 128 may read data from the player tracking card 59 in a variety of ways. For example, the data reading apparatus 128 may read data from a magnetic strip or from an optically readable material such as ink, both of which may be located on a surface of the player tracking card 59. It is also possible to utilize multiple data reading apparatuses to read data from additional magnetic strips or optically readable materials located on the same surface or on different surfaces of the player tracking card 59. As another example, the data reading apparatus 128 may utilize an antenna to couple with a corresponding antenna in the player tracking card 59 so that data is thereby transmitted. The data reading apparatus 128 may be interconnected to the controller 100 so that the data may be stored and possibly acted on, such as by energizing a light generating source 122. While not shown, a data writing apparatus may also be included to write new data to the player tracking card 59. This may be a separate component, or it may be combined with the data reading apparatus 128. The gaming apparatus 20 may also include an energy transfer apparatus 130.

The energy transfer apparatus 130 may be mounted on the second side rail 118 and operatively coupled to the controller 100 through a conductor 132. The energy transfer apparatus 130 may be located in close proximity to a surface of the player tracking card 59 when the player tracking card 59 is disposed in the card reader 58 and positioned in the card illumination position. The energy transfer apparatus 130 may utilize one of many available techniques to transfer energy to the player tracking card 59. For example, the energy transfer apparatus 130 may comprise an antenna or coil having at least one loop or turn. More loops or turns may be utilized to increase the magnetic flux generated, and increase the antenna's range. Additionally, a plethora of antenna designs, both simple and complex, may be utilized to create the desired coupling with a corresponding antenna in the player tracking card 59 (See Fig. 7). This technique is often referred to as inductive coupling by those skilled in the art and is capable of transmitting both power and data between the gaming apparatus 20 and the player tracking card 59. The energy transfer apparatus 130 may also comprise a first metallic plate to transfer energy to the player tracking card 59. The first metallic plate may correspond to and be aligned with a second metallic plate in the player tracking card 59 (See Fig. 8) when the player tracking card 59 is in the card illumination position. This technique is referred to as capacitative coupling by those skilled in the art, and is capable of transmitting or receiving both power and/or data. The transmission and reception of the power and data may be controlled by the controller 100.

The energy transfer apparatus 130 may also comprise a first conductive port, such as a modular plug, to interconnect with a second conductive port located on the player tracking card 59 (see Fig. 9) when the player tracking card 59 is disposed in the card reader 58 and positioned in the card illumination position. The conductive ports may comprise one or more separate connections to transfer power and/or data between the gaming apparatus 20 and the player tracking card 59. The conductive ports may utilize modular plugs to interconnect wherein one of the conductive ports includes at least one male connector (i.e. a metallic prong or pin) and the other conductive port includes a corresponding number of female connectors (i.e. a metallic receptacle) to mate with the male connector and complete a conductive path for energy transmission. The energy transmissions between the gaming apparatus 20 and the player tracking card 59 may be controlled by the controller 100.

Player Tracking Card Embodiments

Fig. 5 illustrates one embodiment of a player tracking card 59a. The player tracking card 59a may include the first card surface 127, a second card surface 136, a third card surface 138, a fourth card surface 140, a fifth card surface 142, and a sixth card surface 144. The second card surface 136 of the player tracking card 59a may be generally parallel to and spaced apart from first card surface 127. The player tracking card 59 may also comprise a light transmissive body portion 146 extending between the first card surface 127 and the second card surface 136.

The transmissive body portion 146 may comprise a clear translucent material, a colored material, multi-colored material, or any other material that may be optically "clear" and capable of transmitting or propagating light signals. The player tracking card 59a may also have a reflective material or coating disposed on at least a portion of the third through sixth card surfaces 138-144 to enhance the transmission of light from the first card surface 127 to the second card surface 136. The reflective material may be disposed on the card surfaces 138-144 with the use of an adhesive. The player tracking card 59a may also have printing, such as advertisement or decoration, disposed on the reflective material, or at least portions of the reflective material.

When the player tracking card 59a is positioned in the card illumination position, the first card surface 127 may be disposed in the card reader 58 and the second card surface 136 may remain visible outside the card reader. Thus, when the player tracking card 59a is positioned in the card illumination position and the first card surface 127 is located adjacent the light generating sources 122, light generated by the light generating sources 122 may be transmitted into the first card surface 127 of the player tracking card 59a and may then be transmitted through the light transmissive body portion 146 of the player tracking card 59a so that the generated light is visible to a user through the second card surface 136. If as in Fig. 4, a portion of the player tracking card 59a remains exposed from the card reader 58 when the player tracking card 59a is in the card illumination position, then light generated by the light generating sources 122 may be visible on the exposed portions of the third, fourth, fifth, and sixth card surfaces 138, 140, 142, and 144.

The player tracking card 59a may also have disposed thereon any other type of material other than the reflective material described above that would comprise the physical properties of having a lower index of refraction to enhance internal reflection of light propagating through the light transmissive body portion. Another alternative and simple technique to enhance the light transmission from the first card surface 127 to the second card surface 136 may be to condition the outer surfaces of the light transmissive body portion 146 so that at least a portion of the third through sixth card surfaces 138-144 may comprise a lower index of refraction, thus increasing the amount of internally reflected light and improving the performance of the player tracking card 59a.

By transmitting light through the transmissive body portion 146 of the player tracking card 59a and making it visible on at least a portion of the exposed player tracking card 59a, information such as player status and machine status may be communicated to the player and other employees of the facility owning the gaming apparatus 20. This may be accomplished by producing varying or repeating patterns of color and/or intensity of the light visible through the player tracking card 59.

The player tracking card 59a of Fig. 5 may also include a data storage device that stores data representing the identification of a player. Many different types of devices to store data may be suitable. Fig. 5 illustrates a magnetic strip 148 on the fifth card surface 142. The location of the magnetic strip 148 on the player tracking card 59a is not important and may be located in a variety of places and comprise a variety of different shapes. The magnetic strip 148 may be aligned with the data reading apparatus 128 so that the information read may be transmitted to the controller 100. The magnetic strip 148 may store a large variety of data, which may include for example, the identification of a player, the player's personal information, the player's gaming habits including the player's frequency of play, the player's betting limits and trends, as well as any other gaming data to be stored and tracked. The data storage device may also comprise more sophisticated apparatuses such as optically readable memories, semiconductor memories such as RAMs, etc. The data storage device 148 and corresponding data reading apparatus 128 (see Fig.

4) may also be configured so that the data reading apparatus 128, or a separate component, is capable of writing data to the data storage device 148 on the player tracking card 59a. Player Tracking Card With Embedded Optic Fibers

Fig. 6. is a perspective view of another embodiment of a player tracking card 59b, wherein the light transmissive body portion 146 may comprise a plurality of optic fibers 150 embedded within the player tracking card 59b. The optic fibers 150 extend between the first card surface 127 and the second, third, and fourth card surfaces 136, 138, and 140. When the player tracking card 59b is disposed in the card reader 58 and positioned in the card illumination position, light from the light generating sources 122 (see Fig. 4) is transmitted to the first card surface 127, through the optic fibers 150, and may be visible on the second card surface 136 and portions of the other card surfaces, such as the third and fourth card surfaces 138 and 140. Thus, by controlling the color, intensity, and pattern of illumination of the light generating sources 122, the gaming apparatus 20 is capable of displaying player status, machine status, etc. to the player and other interested persons. Additionally, the illumination of the card surface or surfaces may be utilized to attract players to a specific gaming apparatus.

The player tracking card 59b may also comprise a data storage device, such as the magnetic strip 148. The magnetic strip 148 may store a variety of gaming data, which may include the identity of the user. Other types of data storage devices known to those skilled in the art may also be used.

Overall Operation of Gaming Unit

One manner in which one or more of the gaming units 20 (and one or more of the gaming units 30) may operate is described below in connection with a number of flowcharts which represent a number of portions or routines of one or more computer programs, which may be stored in one or more of the memories of the controller 100. The computer program(s) or portions thereof may be stored remotely, outside of the gaming unit 20, and may control the operation of the gaming unit 20 from a remote location. Such remote control may be facilitated with the use of a wireless connection, or by an Internet interface that connects the gaming unit 20 with a remote computer (such as one of the network computers 22, 32) having a memory in which the computer program portions are stored. The computer program portions may be written in any high level language such as C, C+ , C+ + or the like or any low-level, assembly or machine language. By storing the computer program portions therein, various portions of the memories 102, 106 are physically and/or structurally configured in accordance with computer program instructions.

Fig. 10 is a flowchart of a main operating routine 200 that may be stored in the memory of the controller 100. Referring to Fig. 10, the main routine 200 may begin operation at block 202 during which an attraction sequence may be performed in an attempt to induce a potential player in a casino to play the gaming unit 20. The attraction sequence may be performed by displaying one or more video images on the display unit 70 and/or causing one or more sound segments, such as voice or music, to be generated via the speakers 62. The attraction sequence may include a scrolling list of games that may be played on the gaming unit 20 and/or video images of various games being played, such as video poker, video blackjack, video slots, video keno, video bingo, etc.

During performance of the attraction sequence, if a potential player makes any input to the gaming unit 20 as determined at block 204, the attraction sequence may be terminated and a game-selection display may be generated on the display unit 70 at block 206 to allow the player to select a game available on the gaming unit 20. The gaming unit 20 may detect an input at block 204 in various ways. For example, the gaming unit 20 could detect if the player presses any button on the gaming unit 20; the gaming unit 20 could determine if the player deposited one or more coins into the gaming unit 20; the gaming unit 20 could determine if player deposited paper currency into the gaming unit; etc.

The game-selection display generated at block 206 may include, for example, a list of video games that may be played on the gaming unit 20 and/or a visual message to prompt the player to deposit value into the gaming unit 20. While the game-selection display is generated, the gaming unit 20 may wait for the player to make a game selection. Upon selection of one of the games by the player as determined at block 208, the controller 100 may cause one of a number of game routines to be performed to allow the selected game to be played. For example, the game routines could include a video poker routine 210, a video blackjack routine 220, a slots routine 230, a video keno routine 240, and a video bingo routine 250. At block 208, if no game selection is made within a given period of time, the operation may branch back to block 202.

After one of the routines 210, 220, 230, 240, 250 has been performed to allow the player to play one of the games, block 260 may be utilized to determine whether the player wishes to terminate play on the gaming unit 20 or to select another game. If the player wishes to stop playing the gaming unit 20, which wish may be expressed, for example, by selecting a "Cash Out" button, the controller 100 may dispense value to the player at block 262 based on the outcome of the game(s) played by the player. The operation may then return to block 202. If the player did not wish to quit as determined at block 260, the routine may return to block 208 where the game-selection display may again be generated to allow the player to select another game.

It should be noted that although five gaming routines are shown in Fig. 10, a different number of routines could be included to allow play of a different number of games. The gaming unit 20 may also be programmed to allow play of different games.

Fig. 11 is a flowchart of an alternative main operating routine 300 that may be stored in the memory of the controller 100. The main routine 300 may be utilized for gaming units 20 that are designed to allow play of only a single game or single type of game. Referring to Fig. 11, the main routine 300 may begin operation at block 302 during which an attraction sequence may be performed in an attempt to induce a potential player in a casino to play the gaming unit 20. The attraction sequence may be performed by displaying one or more video images on the display unit 70 and/or causing one or more sound segments, such as voice or music, to be generated via the speakers 62.

During performance of the attraction sequence, if a potential player makes any input to the gaming unit 20 as determined at block 304, the attraction sequence may be terminated and a game display may be generated on the display unit 70 at block 306. The game display generated at block 306 may include, for example, an image of the casino game that may be played on the gaming unit 20 and/or a visual message to prompt the player to deposit value into the gaming unit 20. At block 308, the gaming unit 20 may determine if the player requested information concerning the game, in which case the requested information may be displayed at block 310. Block 312 may be used to determine if the player requested initiation of a game, in which case a game routine 320 may be performed. The game routine 320 could be any one of the game routines disclosed herein, such as one of the five game routines 210, 220, 230, 240, 250, or another game routine.

After the routine 320 has been performed to allow the player to play the game, block 322 may be utilized to determine whether the player wishes to terminate play on the gaming unit 20. If the player wishes to stop playing the gaming unit 20, which wish may be expressed, for example, by selecting a "Cash Out" button, the controller 100 may dispense value to the player at block 324 based on the outcome of the game(s) played by the player. The operation may then return to block 302. If the player did not wish to quit as determined at block 322, the operation may return to block 308.

Video Poker Fig. 12 is an exemplary display 350 that may be shown on the display unit

70 during performance of the ideo poker routine 210 shown schematically in Fig. 10. Referring to Fig. 12, the display 350 may include video images 352 of a plurality of playing cards representing the player's hand, such as five cards. To allow the player to control the play of the video poker game, a plurality of player- selectable buttons may be displayed. The buttons may include a "Hold" button 354 disposed directly below each of the playing card images 352, a "Cash Out" button 356, a "See Pays" button 358, a "Bet One Credit" button 360, a "Bet Max Credits" button 362, and a "Deal/Draw" button 364. The display 350 may also include an area 366 in which the number of remaining credits or value is displayed. If the display unit 70 is provided with a touch-sensitive screen, the buttons 354, 356, 358, 360, 362, 364 may form part of the video display 350. Alternatively, one or more of those buttons may be provided as part of a control panel that is provided separately from the display unit 70.

Fig. 14 is a flowchart of the video poker routine 210 shown schematically in Fig. 10. Referring to Fig. 14, at block 370, the routine may determine whether the player has requested payout information, such as by activating the "See Pays" button 358, in which case at block 372 the routine may cause one or more pay tables to be displayed on the display unit 70. At block 374, the routine may determine whether the player has made a bet, such as by pressing the "Bet One Credit" button 360, in which case at block 376 bet data corresponding to the bet made by the player may be stored in the memory of the controller 100. At block 378, the routine may determine whether the player has pressed the "Bet Max Credits" button 362, in which case at block 380 bet data corresponding to the maximum allowable bet may be stored in the memory of the controller 100.

At block 382, the routine may determine if the player desires a new hand to be dealt, which may be determined by detecting if the "Deal/Draw" button 364 was activated after a wager was made. In that case, at block 384 a video poker hand may be "dealt" by causing the display unit 70 to generate the playing card images 352. After the hand is dealt, at block 386 the routine may determine if any of the "Hold" buttons 354 have been activated by the player, in which case data regarding which of the playing card images 352 are to be "held" may be stored in the controller 100 at block 388. If the "Deal/Draw" button 364 is activated again as determined at block 390, each of the playing card images 352 that was not "held" may be caused to disappear from the video display 350 and to be replaced by a new, randomly selected, playing card image 352 at block 392. At block 394, the routine may determine whether the poker hand represented by the playing card images 352 currently displayed is a winner. That determination may be made by comparing data representing the currently displayed poker hand with data representing all possible winning hands, which may be stored in the memory of the controller 100. If there is a winning hand, a payout value corresponding to the winning hand may be determined at block 396. At block 398, the player's cumulative value or number of credits may be updated by subtracting the bet made by the player and adding, if the hand was a winner, the payout value determined at block 396. The cumulative value or number of credits may also be displayed in the display area 366 (Fig. 12). Although the video poker routine 210 is described above in connection with a single poker hand of five cards, the routine 210 may be modified to allow other versions of poker to be played. For example, seven card poker may be played, or stud poker may be played. Alternatively, multiple poker hands may be simultaneously played. In that case, the game may begin by dealing a single poker hand, and the player may be allowed to hold certain cards. After deciding which cards to hold, the held cards may be duplicated in a plurality of different poker hands, with the remaining cards for each of those poker hands being randomly determined.

Alternatively, one or more of those buttons may be provided as part of a control panel that is provided separately from the display unit 70.

Fig. 15 is a flowchart of the video blackjack routine 220 shown schematically in Fig. 10. Referring to Fig. 15, the video blackjack routine 220 may begin at block 420 where it may determine whether a bet has been made by the player. That may be determined, for example, by detecting the activation of either the "Bet One Credit" button 414 or the "Bet Max Credits" button 416. At block 422, bet data corresponding to the bet made at block 420 may be stored in the memory of the controller 100. At block 424, a dealer's hand and a player's hand may be "dealt" by making the playing card images 402, 404 appear on the display unit 70.

At block 426, the player may be allowed to be "hit, " in which case at block 428 another card will be dealt to the player's hand by making another playing card image 404 appear in the display 400. If the player is hit, block 430 may determine if the player has "bust," or exceeded 21. If the player has not bust, blocks 426 and

428 may be performed again to allow the player to be hit again.

If the player decides not to hit, at block 432 the routine may determine whether the dealer should be hit. Whether the dealer hits may be determined in accordance with predetermined rules, such as the dealer always hit if the dealer's hand totals 15 or less. If the dealer hits, at block 434 the dealer's hand may be dealt another card by making another playing card image 402 appear in the display 400. At block 436 the routine may determine whether the dealer has bust. If the dealer has not bust, blocks 432, 434 may be performed again to allow the dealer to be hit again. If the dealer does not hit, at block 436 the outcome of the blackjack game and a corresponding payout may be determined based on, for example, whether the player or the dealer has the higher hand that does not exceed 21. If the player has a winning hand, a payout value corresponding to the winning hand may be determined at block 440. At block 442, the player's cumulative value or number of credits may be updated by subtracting the bet made by the player and adding, if the player won, the payout value determined at block 396. The cumulative value or number of credits may also be displayed in the display area 418 (Fig. 13).

At block 474, the routine may determine whether the player has pressed one of the payline-selection buttons 460, in which case at block 476 data corresponding to the number of paylines selected by the player may be stored in the memory of the controller 100. At block 478, the routine may determine whether the player has pressed one of the bet-selection buttons 462, in which case at block 480 data corresponding to the amount bet per payline may be stored in the memory of the controller 100. At block 482, the routine may determine whether the player has pressed the "Max Bet" button 466, in which case at block 484 bet data (which may include both payline data and bet-per- payline data) corresponding to the maximum allowable bet may be stored in the memory of the controller 100. If the "Spin" button 464 has been activated by the player as determined at block 486, at block 488 the routine may cause the slot machine reel images 452 to begin "spining" so as to simulate the appearance of a plurality of spinning mechanical slot machine reels. At block 490, the routine may determine the positions at which the slot machine reel images will stop, or the particular symbol images 454 that will be displayed when the reel images 452 stop spinning. At block

492, the routine may stop the reel images 452 from spinning by displaying stationary reel images 452 and images of three symbols 454 for each stopped reel image 452. The virtual reels may be stopped from left to right, from the perspective of the player, or in any other manner or sequence. The routine may provide for the possibility of a bonus game or round if certain conditions are met, such as the display in the stopped reel images 452 of a particular symbol 454. If there is such a bonus condition as determined at block 494, the routine may proceed to block 496 where a bonus round may be played. The bonus round may be a different game than slots, and many other types of bonus games could be provided. If the player wins the bonus round, or receives additional credits or points in the bonus round, a bonus value may be determined at block 498. A payout value corresponding to outcome of the slots game and/or the bonus round may be determined at block 500. At block 502, the player's cumulative value or number of credits may be updated by subtracting the bet made by the player and adding, if the slot game and/or bonus round was a winner, the payout value determined at block 500.

Although the above routine has been described as a virtual slot machine routine in which slot machine reels are represented as images on the display unit 70, actual slot machine reels that are capable of being spun may be utilized instead. Video Keno

Fig. 17 is an exemplary display 520 that may be shown on the display unit 70 during performance of the video keno routine 240 shown schematically in Fig. 10. Referring to Fig. 17, the display 520 may include a video image 522 of a plurality of numbers that were selected by the player prior to the start of a keno game and a video image 524 of a plurality of numbers randomly selected during the keno game. The randomly selected numbers may be displayed in a grid pattern.

To allow the player to control the play of the keno game, a plurality of player-selectable buttons may be displayed. The buttons may include a "Cash Out" button 526, a "See Pays" button 528, a "Bet One Credit" button 530, a "Bet Max

Credits" button 532, a "Select Ticket" button 534, a "Select Number" button 536, and a "Play" button 538. The display 520 may also include an area 540 in which the number of remaining credits or value is displayed. If the display unit 70 is provided with a touch-sensitive screen, the buttons may form part of the video display 520. Alternatively, one or more of those buttons may be provided as part of a control panel that is provided separately from the display unit 70.

Fig. 19 is a flowchart of the video keno routine 240 shown schematically in Fig. 10. The keno routine 240 may be utilized in connection with a single gaming unit 20 where a single player is playing a keno game, or the keno routine 240 may be utilized in connection with multiple gaming units 20 where multiple players are playing a single keno game. In the latter case, one or more of the acts described below may be performed either by the controller 100 in each gaming unit or by one of the network computer 22, 32 to which multiple gaming units 20 are operatively connected. Referring to Fig. 19, at block 550, the routine may determine whether the player has requested payout information, such as by activating the "See Pays" button 528, in which case at block 552 the routine may cause one or more pay tables to be displayed on the display unit 70. At block 554, the routine may determine whether the player has made a bet, such as by having pressed the "Bet One Credit" button 530 or the "Bet Max Credits" button 532, in which case at block 556 bet data corresponding to the bet made by the player may be stored in the memory of the controller 100. After the player has made a wager, at block 558 the player may select a keno ticket, and at block 560 the ticket may be displayed on the display 520. At block 562, the player may select one or more game numbers, which may be within a range set by the casino. After being selected, the player's game numbers may be stored in the memory of the controller 100 at block 564 and may be included in the image 522 on the display 520 at block 566. After a certain amount of time, the keno game may be closed to additional players (where a number of players are playing a single keno game using multiple gambling units 20). If play of the keno game is to begin as determined at block 568, at block 570 a game number within a range set by the casino or other facility may be randomly selected either by the controller 100 or a central computer operatively connected to the controller, such as one of the network computers 22, 32. At block 572, the randomly selected game number may be displayed on the display unit 70 and the display units 70 of other gaming units 20 (if any) which are involved in the same keno game. At block 574, the controller 100 (or the central computer noted above) may increment a count which keeps track of how many game numbers have been selected at block 570.

At block 576, the controller 100 (or one of the network computers 22, 32) may determine whether a maximum number of game numbers within the range have been randomly selected. If not, another game number may be randomly selected at block 570. If the maximum number of game numbers has been selected, at block 578 the controller 100 (or a central computer) may determine whether there are a sufficient number of matches between the game numbers selected by the player and the game numbers selected at block 570 to cause the player to win. The number of matches may depend on how many numbers the player selected and the particular keno rules being used.

If there are a sufficient number of matches, a payout may be determined at block 580 to compensate the player for winning the game. The payout may depend on the number of matches between the game numbers selected by the player and the game numbers randomly selected at block 570. At block 582, the player's cumulative value or number of credits may be updated by subtracting the bet made by the player and adding, if the keno game was won, the payout value determined at block 580. The cumulative value or number of credits may also be displayed in the display area 540 (Fig. 17).

Video Bingo

Fig. 20 is an exemplary display 600 that may be shown on the display unit 70 during performance of the video bingo routine 250 shown schematically in Fig. 10. Referring to Fig. 20, the display 600 may include one or more video images

602 of a bingo card and images of the bingo numbers selected during the game. The bingo card images 602 may have a grid pattern.

To allow the player to control the play of the bingo game, a plurality of player-selectable buttons may be displayed. The buttons may include a "Cash Out" button 604, a "See Pays" button 606, a "Bet One Credit" button 608, a "Bet Max

Credits" button 610, a "Select Card" button 612, and a "Play" button 614. The display 600 may also include an area 616 in which the number of remaining credits or value is displayed. If the display unit 70 is provided with a touch-sensitive screen, the buttons may form part of the video display 600. Alternatively, one or more of those buttons may be provided as part of a control panel that is provided separately from the display unit 70.

Fig. 21 is a flowchart of the video bingo routine 250 shown schematically in Fig. 10. The bingo routine 250 may be utilized in connection with a single gaming unit 20 where a single player is playing a bingo game, or the bingo routine 250 may be utilized in connection with multiple gaming units 20 where multiple players are playing a single bingo game. In the latter case, one or more of the acts described below may be performed either by the controller 100 in each gaming unit 20 or by one of the network computers 22, 32 to which multiple gaming units 20 are operatively connected. Referring to Fig. 21, at block 620, the routine may determine whether the player has requested payout information, such as by activating the "See Pays" button 606, in which case at block 622 the routine may cause one or more pay tables to be displayed on the display unit 70. At block 624, the routine may determine whether the player has made a bet, such as by having pressed the "Bet One Credit" button 608 or the "Bet Max Credits" button 610, in which case at block 626 bet data corresponding to the bet made by the player may be stored in the memory of the controller 100.

After the player has made a wager, at block 628 the player may select a bingo card, which may be generated randomly. The player may select more than one bingo card, and there may be a maximum number of bingo cards that a player may select. After play is to commence as determined at block 632, at block 634 a bingo number may be randomly generated by the controller 100 or a central computer such as one of the network computers 22, 32. At block 636, the bingo number may be displayed on the display unit 70 and the display units 70 of any other gaming units 20 involved in the bingo game.

At block 638, the controller 100 (or a central computer) may determine whether any player has won the bingo game. If no player has won, another bingo number may be randomly selected at block 634. If any player has bingo as determined at block 638, the routine may determine at block 640 whether the player playing that gaming unit 20 was the winner. If so, at block 642 a payout for the player may be determined. The payout may depend on the number of random numbers that were drawn before there was a winner, the total number of winners (if there was more than one player), and the amount of money that was wagered on the game. At block 644, the player's cumulative value or number of credits may be updated by subtracting the bet made by the player and adding, if the bingo game was won, the payout value determined at block 642. The cumulative value or number of credits may also be displayed in the display area 616 (Fig. 20).
