Additional features are described herein, and will be apparent from the following Detailed Description and the figures.
In various embodiments, the present disclosure generally relates to gaming systems and methods of operating such gaming systems that provide plays of a draw poker game (such as a primary wagering single hand or multi-hand five card draw video poker game) that includes selective re-deals for the initial hands that are no-hold hands. In various embodiments, for one or more or each play of the draw poker game, the gaming system automatically determines if the initial hand of the draw poker game is one of a plurality of different no-hold hands. For one or more or each such play of the draw poker game where the gaming system determines that the initial hand is one of the no-hold hands, the gaming system enables the player to elect to have the gaming system replace that no-hold initial hand with a second initial hand for that play of the draw poker game. For each such play of the draw poker game where the player elects to have the gaming system replace the no-hold initial hand with the second initial hand, the gaming system replaces the no-hold initial hand with the second initial hand for that play of the draw poker game. The gaming system then uses that second initial hand for the rest of that play of the draw poker game.
In various embodiments of the present disclosure, a no-hold initial hand is an initial hand for a play of a draw poker game, wherein based on the deck of cards and the paytable for the draw poker game, the initial hand provides an expected value of the play of the draw poker game that is maximized by the player holding none of the cards of that initial hand for the play of the draw poker game. When a player receives a no-hold initial hand in a play of a draw poker game (such as in a play of a five card draw poker game), the best strategy for the player is to hold none of the initial cards of that initial hand (i.e., to discard all of the cards of the initial hand) based on the deck of cards and the paytable for that play of the draw poker game. In such case, holding any cards of such initial hand is a sub-optimal strategy based on the deck of cards and the respective paytable for the play of the draw poker game. Players thus often discard all five cards of a no-hold initial hand when playing five card draw poker to maximize their return. Such no-hold initial hands are viewed very unfavorably by players. Players prefer to have initial hands with one or more cards to hold because such initial hands provided significantly higher expected values than such no-hold initial hands.
For example, in various embodiments, a no-hold initial hand can be an initial hand for a draw poker game in which the initial hand provides an expected value or return of the play of the draw poker game that is less than 0.3.
For example, in various embodiments, a no-hold initial hand can be an initial hand for a draw poker game in which the initial hand includes: (1) no winning card combinations based on the paytable for that draw poker game (such as no pairs of Jacks or better, no two pairs, no three-of-a-kinds, no four-of-a-kinds, no straights, no flushes, no full houses, and no straight flushes); (2) no matching pairs (such as no matching 2s, 3s, 4s, 5s, 6s, 7s, 8s, 9s, or 10s); (3) no combinations of cards that are missing one card from forming a straight, a flush, or a straight flush); and (4) no royal cards (such as no Jacks, Queens, Kings, or Aces).
The present disclosure contemplates that the determinations and the replacements of the no-hold initial hands can be selective in various different manners as further described herein. Specifically, in various different embodiments of the present disclosure, the determination of the no-hold hands can be selectively made by the gaming system for one, more, or each play of the draw poker game, the determination of whether to enable the player to elect to cause a replacement of a no-hold initial hand can be selectively made by the gaming system for one, more, or each play of the draw poker game, and/or the election to replace the no-hold initial hand can be selectively made by the gaming system or the player for, one, more, or each play of the draw poker game.
In various embodiments of the present disclosure, the gaming system automatically evaluates the initial hand for each play of the draw poker game to determine if the initial hand is one of the plurality of different no-hold hands based on the paytable for that draw poker game. In these embodiments, the gaming system provides the player the option to replace each no-hold initial hand that the player receives for each play of the draw poker game. Thus, the gaming system provides the selectivity to the player in these embodiments.
In various other embodiments of the present disclosure, the gaming system automatically evaluates the initial hand for each play of the draw poker game to determine if the initial hand is one of the plurality of different no-hold hands based on the paytable for that draw poker game. In these embodiments, the gaming system selectively determines whether to provide the player the option to cause the gaming system to replace such no-hold initial hand that the player receives for such play of the draw poker game. In these embodiments, the gaming system selectively provides the player the option to cause a replacement of the no-hold initial hand for only certain plays of the draw poker game in which the player receives no-hold initial hands. This selective determination of whether to provide the player the option to cause a replacement of the no-hold initial hand for the play of a draw poker game can be based one or more conditions.
In various other embodiments of the present disclosure, the gaming system evaluates the initial hand for the play of the draw poker game to determine if the initial hand is one of the plurality of different no-hold hands based on the paytable for that draw poker game for only certain plays of the draw poker game. This selective determination of whether the initial hand is a no-hold initial hand for the play of draw poker game can be based one or more conditions.
Each of the above mentioned one or more conditions can be any suitable conditions such as but not limited to: (a) whether there is an accumulated quantity of available initial hand replacements such as in a bank or meter that is available to the player; (b) whether the player has made a sufficient wager; (c) whether the player has discarded a predetermined quantity of no-hold hands in a series of plays of the draw poker game; or (d) whether the player has discarded a predetermined quantity of sequential no-hold hands. In various embodiments where a bank or meter is employed, the gaming system can suitably display the bank or meter, the quantity of no-hold initial hand replacements in the bank or meter, the quantity of hand remaining until a no-hold hand replacement is available, or any other suitable countdown indication.
In various other embodiments of the present disclosure, the gaming system makes the determination of whether to evaluate and/or enable replacement of the no-hold initial hand in any one of a plurality of different manners. For example, the gaming system can make one or more of these determinations: (1) on a random basis, (2) for every play of the game, or (3) on another regular basis such as every 5th hand or every 5th no-hold hand.
In various embodiments of the present disclosure, the gaming system enables the player to make the election of whether to cause a replacement of a no-hold initial hand for the play of the draw poker game. Thus, the player decision on whether to elect to cause a replacement of the initial hand that is a no hold hand is selective. For various different reasons, a player may or may not want to replace a no-hold initial hand. For example, the player may believe that an initial hand with a two of hearts is a lucky hand and may not want that initial hand replaced.
In various other embodiments of the present disclosure, the gaming system automatically replaces a no-hold initial hand for the play of the draw poker game without asking or enabling the player to elect to cause such replacement.
In various embodiments of the present disclosure, the gaming system determines the second initial hand that replaces a no-hold initial hand for the play of the draw poker game by making a new random determination of the cards for the second initial hand after the determination is made to replace the no-hold initial hand. In these embodiments, the gaming system does not know what the second initial hand will be until that random determination is made and thus cannot and does not display any information regarding the second initial hand to the player.
In various other embodiments of the present disclosure, the gaming system determines the second initial hand that would replace a no-hold initial hand for the play of the draw poker game at the same time the gaming system determines the initial hand (but does not display the second initial hand at that point in time). In various such embodiments, these determinations of the initial hand and the second initial hand for the play of the draw poker game are from identical but separate sets of cards (such as identical but separate virtual decks of 52 cards). In these embodiments, the likelihood that the second initial hand will also be a no-hold hand is the same as for the initial hand. In various other embodiments, these determinations of the initial hand and the second initial hand for the play of the draw poker game are from a single set of cards (such as a single virtual deck of cards). In these other embodiments, the likelihood that the second initial hand will also be a no-hold hand is substantially lower. In various such embodiments, the gaming system does not display any information regarding the second initial hand to the player. In various other embodiments, the gaming system displays certain information regarding the second initial hand to the player such as but not limited to a recommendation to replace the initial hand based on the known but un-displayed second hand.
In various embodiments of the present disclosure, the gaming system can display the second initial hand in any suitable manner. For example, the gaming system can display the second initial hand in addition to maintaining the display of the initial hand so that the player can see both hands—but only use the second initial hand. In other example embodiments, the gaming system can uses a suitable device (such as one or more reels or wheels) to display the second initial hand (such as in a reel or wheel poker version).
In various embodiments of the present disclosure, the gaming system can enable the player to hold one or more of the cards from the initial hand to be used in the second initial hand.
In operation of this example embodiment, the process 100 begins after the gaming system establishes a credit balance for a player (such as but not limited to after a physical acceptor of the gaming system receives and validates physical currency, a physical ticket associated with a monetary value, or an electronic payment or transfer of funds from a player account).
The gaming system is also configured to receive a game-initiation input by the player (such as an actuation of a physical deal button or a virtual deal button via a touch screen) and, responsive to receipt of the game-initiation input, the gaming system deducts a wager from the credit balance and initiates a play of a multi-hand draw poker game associated with a paytable, as indicated by block 102. While a multi-hand draw poker game is used as an example herein, the selective no-hold initial hand replacement feature of the present disclosure can alternatively be employed with a single hand draw poker game. The employed paytable for the play of the draw poker game is determined based on the type of draw poker game being played and the wager (and in various embodiments the wagering game's denomination). Table 1 below includes an example paytable for an example 5 credit maximum wager per hand Jacks or Better Five Card Draw Multi-Hand Draw Poker Game. This example paytable includes the different winning hand categories, the winning hands associated with the different winning hand categories, and the payout awards associated with the winning hand categories. The winning hand categories are listed from highest to lowest payout award ranking. Although not shown here, winning hands can also be ranked within the different winning hand categories. In this example embodiment, the winning hands of the “Jacks or Better” winning hand category include a pair of Jacks, a pair of Queens, a pair of Kings, and a pair of Aces.

The gaming system determines and displays an initial hand including multiple cards randomly selected from a set of a plurality of different cards, as indicated by block 104. In one example, the set of cards includes the cards of a virtual standard 52-card deck, and the gaming system randomly determines (without replacement) 5 of the cards of the standard 52-card deck to include in the initial hand. For example, a play of the multi-hand draw poker game can include an initial hand and ninety-nine additional hands for this example play of the multi-hand poker game (such as shown in
In this example, the remaining 48 cards of the virtual 52-card deck are used to randomly select any replacement cards for any of the initial cards of the initial hand (or a second initial hand as described below) that are not held by the player as described below. In this example, the gaming system also displays place holders for each of the cards that will eventually be added to each additional hand included in the play of the multi-hand draw poker game. For example, the play of the multi-hand draw poker game includes an initial hand and ninety-nine additional hands for this example play of the multi-hand draw poker game, where the initial cards for the initial hand are displayed and place holders are displayed for all of the cards in the ninety-nine additional hands (such as shown in
After forming the initial hand, the gaming system determines if the initial hand is a no-hold hand, as indicated by block 106. In other words, the gaming system makes a no-hold hand determination based on the cards of the initial hand. In this example embodiment, for every play of the draw poker game, the gaming system determines whether the initial hand for that play of the draw poker game is one of a plurality of different no-hold hands, and if that initial hand is a no-hold hand for that play of the draw poker game, the gaming system provides the player the opportunity to cause a replacement of that no-hold initial hand with a second initial hand for that play of the draw poker game. As mentioned above, this determination by the gaming system can be alternatively selectively made based on one or more conditions and does not need to be provided for every play of the game in alternative embodiments of the present disclosure.
If the gaming system determines the initial hand is a no-hold hand, the gaming system enables the player to request a second initial hand, as indicated by block 108. The gaming system can do this in any one of a plurality of different manners in accordance with the present disclosure. In one example embodiment, the gaming system displays an indication to the player that the initial hand is a no-hold hand and enables the player to make an input indicating that the player elects to have the gaming system replace the no-hold initial hand with a second initial hand. This can be in the form of one or more physical or video input devices or buttons. The player can therefore make the decision as to whether to use the initial hand for the play of the draw poker game or have the gaming system replace the initial hand with a second initial hand for that play of the draw poker game. The input to use the initial hand for the play of the game can simply be the inputs for holding one or more cards of the initial hand in combination with the draw input, or can be the draw input alone if the player does not want to hold any of the cards of the initial hand.
If the player makes an input indicating that the player elects to have the gaming system replace the initial hand with the second initial hand, the gaming system determines and displays a second initial hand including multiple cards randomly selected from a set of a plurality of different cards, as indicated by block 110. As indicated above, this determination of the second initial hand can be performed by the gaming system either before or after the player election. If the gaming system determines the initial player hand is not a no-hold hand, the gaming system enables the player to play the rest of the draw poker game using the initial hand. Thus, in these different situations, the gaming system enables the player to play the rest of the game using either the respective initial hand or the second initial hand that replaces the initial hand. In various embodiments, the gaming system will cause a display of the second initial hand replacing the display of the initial hand after the player election to cause the replacement of the initial hand with the second initial hand.
More specifically, for the play of the draw poker game, after determining and displaying the initial player hand, making the no-hold hand determination for the initial hand, and either: (a) maintaining the displayed initial hand as the player hand, or (b) determining and displaying the second initial hand, the gaming system enables player input of: (1) a hold input for each card in the respective initial hand or the second initial hand; and (2) a draw input, as indicated by block 112. The gaming system monitors for receipt of the card hold input (or inputs) and/or the draw input, as indicated by diamonds 114 and 120. This enables the player to choose which of the cards of the initial hand or the second initial hand (if such second initial hand replaces the initial hand) to hold and which of the cards of the initial hand or the second initial hand (if such second initial hand replaces the initial hand) to discard (if any). Responsive to the gaming system determining at diamond 114 that a card hold input identifying a particular card has been received, the gaming system designates that card as a held card, as indicated by block 116. For example, the player may select (via an input device) to hold the first card, the second card, and the third card of the cards of the second initial hand (such as shown in
Responsive to detection of the hold input, the gaming system can duplicate each selected held card to each of the additional hands included in this play of the multi-hand draw poker game, as indicated by block 118. For example, this example play of the multi-hand draw poker game includes the initial hand (if the second initial hand if such second initial hand replaces the initial hand) and ninety-nine additional hands. As such, in this example play of the multi-hand poker game, the gaming system reveals a face-up card in each of the additional hands having the same suit and value as each of the held cards of the initial hand or the second initial hand (if such second initial hand replaces the initial hand). In the above example in which the first card, the second card, and the third card of the second initial hand are designated as held cards, the gaming system duplicates the first card, the second card, and the third card of the second initial hand to each of the additional ninety-nine player hands (as partly shown in
Responsive to the gaming system determining at diamond 120 that a draw input has not been received, the gaming system returns to diamond 114.
Responsive to the gaming system determining at diamond 120 that the draw input has been received, the gaming system determines whether the initial hand or the second initial hand (if such second initial hand replaces the initial hand) includes any non-held cards, as indicated by diamond 122.
Responsive to the gaming system determining at diamond 122 that the initial hand or the second initial hand (if such second initial hand replaces the initial hand) does not include any non-held cards, the gaming system proceeds to block 128, as described below.
Responsive to the gaming system determining at diamond 122 that the initial hand or the second initial hand (if such second initial hand replaces the initial hand) includes one or more non-held cards, the gaming system replaces each non-held card of the initial hand or the second initial hand (if such second initial hand replaces the initial hand) with a replacement card randomly selected from the remaining cards in the respective set of cards to complete that hand, as indicated by block 124. For instance, the gaming system randomly selects the replacement card(s) from the 48 remaining cards of the standard 52-card deck used for the second initial hand (such as shown in
The gaming system then evaluates each completed hand for any awards, as indicated by block 128. For example, the gaming system can evaluate each of the hands to determine any award to issue the player for that hand based on the cards of that hand. It should be appreciated that in other embodiments, the gaming system can evaluate each hand for any award for that hand as soon as the gaming system completes that hand.
The gaming system displays any award associated with each winning hand, as indicated by block 130. These awards can be displayed in any suitable manner.
In this illustrated example embodiment, to activate the play of the draw poker game, the gaming system requires placement of a wager. In certain embodiments, to activate the no-hold hand replacement feature described herein, the gaming system can require at least a designated wager amount to be made such as the maximum wager amount. Here, the maximum wager is 500 credits (5 credits on each of the one hundred hands), though it can be any suitable amount. In various embodiments as stated above, the gaming system activates the no-hold hand replacement feature for each play of the poker game without requiring payment of a separate activation fee or placement of a particular or minimum wager amount (as in the example provided below). In various embodiments, the gaming system requires placement of a particular wager (such as the maximum wager) to activate the no-hold hand replacement feature. In various embodiments, the gaming system requires placement of a minimum wager amount and payment of an activation fee to activate the no-hold hand replacement feature. In various embodiments, the gaming system requires placement of a minimum wager amount and no payment of an activation fee to activate the no-hold hand replacement feature.
In this example, before, during, and after the play of the draw poker game, at various points the gaming system displays one or more of a plurality of buttons actuatable via a touch screen including: (1) a SEE PAYS/HELP button 270, (2) a MORE GAMES button 272, (3) a SPEED button 274, (4) a BET ONE button 276, (5) a BET MAX button 278, and (6) a DEAL/DRAW button 280. Responsive to the gaming system receiving an actuation of the SEE PAYS/HELP button 270, the gaming system displays an interactive menu that includes the rules of the draw poker game, the paytable associated with the draw poker game, and other such draw poker game information. Responsive to the gaming system receiving an actuation of the MORE GAMES button 272, the gaming system displays an interactive menu of additional games the player can play via the gaming system. Responsive to the gaming system receiving an actuation of the SPEED button 274, the gaming system modifies the speed at which the gaming system displays plays of the draw poker game. Responsive to the gaming system receiving an actuation of the BET ONE button 276, the gaming system increases the player wager by 1 credit per hand. Responsive to the gaming system receiving an actuation of the BET MAX button 278, the gaming system increases the player wager to 5 credits per hand. Responsive to the gaming system receiving an actuation of the DEAL/DRAW button 280 before a play of the draw poker game has been initiated, the gaming system places a wager and initiates a play of the draw poker game. Responsive to the gaming system receiving an actuation of the DEAL/DRAW button 280 after a play of the draw poker game has been initiated, the gaming system replaces any non-held cards with replacement cards, and, if necessary replaces and/or adds one or more cards to the additional hands so each additional hand includes five cards, as described above and below. While this illustrated embodiment designates a 5 credit per hand wager as being the maximum wager level, it should be appreciated that the gaming system can designate other suitable wager amounts for the maximum wager level for the play of the draw poker game.
Before or during play of the draw poker game, at various points the gaming system displays a plurality of meters including: (1) a credit meter 290 that indicates the player credit balance, (2) a wager meter 292 that displays the player wager for a play of the draw poker game, and (3) an award meter 294 that displays any awards won for a play of the draw poker game. While in this example embodiment the gaming system indicates the player credit balance, the player wager, and any awards in credits, the gaming system can also indicate them in currency (e.g., U.S. dollars).
211, a 3
212, a 7♥ 213, an 8
214, and a 10♦ 215) from a virtual set of cards to form an initial hand 210. In this example embodiment, the virtual set of cards includes the cards of a standard 52-card deck. The set of cards can include any suitable quantity of any suitable cards in other embodiments. The set of cards in this example include the cards in a virtual deck of 52 cards maintained by the gaming system. Thus, after these initial five cards are selected, the set of cards includes 48 remaining cards.
This illustrated example embodiment of the play of the draw poker game includes ninety-nine additional hands (not individually labeled). As such, each of the additional hands is associated with a respective set of cards that includes the cards of a standard 52-card deck, and after the initial five cards are selected for the initial hand, each set of cards includes 48 remaining cards (i.e., the 52 initial cards minus the 5 cards dealt to the initial hand). If the second initial hand replaces the initial hand, then each of the additional hands is associated with a respective set of cards that includes the cards of a standard 52-card deck, and after the initial five cards are selected for the second hand, each set of cards includes 48 remaining cards (i.e., the 52 initial cards minus the 5 cards dealt to the second initial hand). In this illustrated example embodiment, each of the additional hands include five cards displayed in a face-down position. In this illustrated example embodiment, the face-down cards are place holders for cards to eventually be in these additional hands (e.g., when the additional hands are completed).
In this illustrated example, as shown in ), the second card 212 (e.g., a 3
), the third card 213 (e.g., a 7♥), the fourth card 214 (e.g., an 8
), and the fifth card 215 (e.g., a 10♦).
In this illustrated example, the gaming system determines that this initial hand 210 is one of the plurality of different no-hold hands, and the gaming system displays an indication that this initial hand 210 is a no-hold hand as indicated at the top of the display screen of
Responsive to the player pressing the REPLACE NO-HOLD INITIAL HAND input 296, as shown in ), the second card 212A (e.g., a 7
), the third card 213A (e.g., a 7♥), the fourth card 214A (e.g., a 2
), and the fifth card 215A (e.g., a 9
). This second initial hand includes a winning symbol combination of three 7's and is thus substantially better than the no-hold initial hand 210.
The gaming system enables the player to choose one or more of the cards 211A, 212A, 213A, 214A, and 215A of the second initial hand 210A to hold. The player may choose to hold up to all of the cards 211A, 212A, 213A, 214A, and 215A of the second initial hand 210A. The gaming system discards any non-held cards from the second initial hand 210A and replaces any non-held cards with replacement cards from the cards remaining in the set of cards associated with that hand. In various embodiments, the gaming system duplicates each held card from the second initial hand to each additional hand.
In this example, the held cards from the second initial hand 210A for the gaming system are duplicated in each additional hand as shown in
As also shown in 216 and a 7♦ 217) for the second initial hand 210A from the remaining cards in the set of cards associated with the second initial hand and replaces the non-held cards (e.g., the 2
214 and the 9
215) with these replacement cards. The gaming system also replaces any non-held cards or the one or more place holders (e.g., face-down cards) of each of the additional hands with one or more randomly selected replacement cards so that each of the additional hands include five cards (e.g., the gaming system completes these hands). Specifically, in the illustrated example embodiment, the gaming system completes each additional hand by randomly selecting two cards from the respective set of 48 cards associated with that additional hand and replaces the two place holder cards of that additional hand with the randomly selected cards for that hand. In this illustrated example embodiment, the each additional hand includes five cards when completed. In this example embodiment, the gaming system forms the completed initial player hand and the completed additional hands from separate yet initially identical sets of 48 remaining cards, though this can differ in other embodiments.
In this illustrated example embodiment, for each completed hand, the gaming system: (1) determines whether to issue an award to the player based on the cards of that player hand for the current play of the poker game, and (2) in response to determining to issue an award to the player for that player hand, the gaming system displays any award associated with the winning hand category of the selected player hand. In this illustrated example embodiment, the gaming system determines whether to issue an award to the player for the current play of the poker game based on the cards of the hand and the paytable of the poker game (e.g., the example Table 1 above).

In certain such embodiments, computerized instructions for controlling any games (such as any primary or base games and/or any secondary or bonus games) displayed by the EGM (or personal gaming device) are executed by the central server, central controller, or remote host. In such “thin client” embodiments, the central server, central controller, or remote host remotely controls any games (or other suitable interfaces) displayed by the EGM (or personal gaming device), and the EGM (or personal gaming device) is utilized to display such games (or suitable interfaces) and to receive one or more inputs or commands. In other such embodiments, computerized instructions for controlling any games displayed by the EGM (or personal gaming device) are communicated from the central server, central controller, or remote host to the EGM (or personal gaming device) and are stored in at least one memory device of the EGM (or personal gaming device). In such “thick client” embodiments, the at least one processor of the EGM (or personal gaming device) executes the computerized instructions to control any games (or other suitable interfaces) displayed by the EGM (or personal gaming device).
In various embodiments in which the gaming system includes a plurality of EGMs (or personal gaming devices), one or more of the EGMs (or personal gaming devices) are thin client EGMs (or personal gaming devices) and one or more of the EGMs (or personal gaming devices) are thick client EGMs (or personal gaming devices). In other embodiments in which the gaming system includes one or more EGMs (or personal gaming devices), certain functions of one or more of the EGMs (or personal gaming devices) are implemented in a thin client environment, and certain other functions of one or more of the EGMs (or personal gaming devices) are implemented in a thick client environment. In one such embodiment in which the gaming system includes an EGM (or personal gaming device) and a central server, central controller, or remote host, computerized instructions for controlling any primary or base games displayed by the EGM (or personal gaming device) are communicated from the central server, central controller, or remote host to the EGM (or personal gaming device) in a thick client configuration, and computerized instructions for controlling any secondary or bonus games or other functions displayed by the EGM (or personal gaming device) are executed by the central server, central controller, or remote host in a thin client configuration.
In certain embodiments in which the gaming system includes: (a) an EGM (or personal gaming device) configured to communicate with a central server, central controller, or remote host through a data network; and/or (b) a plurality of EGMs (or personal gaming devices) configured to communicate with one another through a data network, the data network is a local area network (LAN) in which the EGMs (or personal gaming devices) are located substantially proximate to one another and/or the central server, central controller, or remote host. In one example, the EGMs (or personal gaming devices) and the central server, central controller, or remote host are located in a gaming establishment or a portion of a gaming establishment.
In other embodiments in which the gaming system includes: (a) an EGM (or personal gaming device) configured to communicate with a central server, central controller, or remote host through a data network; and/or (b) a plurality of EGMs (or personal gaming devices) configured to communicate with one another through a data network, the data network is a wide area network (WAN) in which one or more of the EGMs (or personal gaming devices) are not necessarily located substantially proximate to another one of the EGMs (or personal gaming devices) and/or the central server, central controller, or remote host. For example, one or more of the EGMs (or personal gaming devices) are located: (a) in an area of a gaming establishment different from an area of the gaming establishment in which the central server, central controller, or remote host is located; or (b) in a gaming establishment different from the gaming establishment in which the central server, central controller, or remote host is located. In another example, the central server, central controller, or remote host is not located within a gaming establishment in which the EGMs (or personal gaming devices) are located. In certain embodiments in which the data network is a WAN, the gaming system includes a central server, central controller, or remote host and an EGM (or personal gaming device) each located in a different gaming establishment in a same geographic area, such as a same city or a same state. Gaming systems in which the data network is a WAN are substantially identical to gaming systems in which the data network is a LAN, though the quantity of EGMs (or personal gaming devices) in such gaming systems may vary relative to one another.
In further embodiments in which the gaming system includes: (a) an EGM (or personal gaming device) configured to communicate with a central server, central controller, or remote host through a data network; and/or (b) a plurality of EGMs (or personal gaming devices) configured to communicate with one another through a data network, the data network is an internet (such as the Internet) or an intranet. In certain such embodiments, an Internet browser of the EGM (or personal gaming device) is usable to access an Internet game page from any location where an Internet connection is available. In one such embodiment, after the EGM (or personal gaming device) accesses the Internet game page, the central server, central controller, or remote host identifies a player before enabling that player to place any wagers on any plays of any wagering games. In one example, the central server, central controller, or remote host identifies the player by requiring a player account of the player to be logged into via an input of a unique player name and password combination assigned to the player. The central server, central controller, or remote host may, however, identify the player in any other suitable manner, such as by validating a player tracking identification number associated with the player; by reading a player tracking card or other smart card inserted into a card reader (as described below); by validating a unique player identification number associated with the player by the central server, central controller, or remote host; or by identifying the EGM (or personal gaming device), such as by identifying the MAC address or the IP address of the Internet facilitator. In various embodiments, once the central server, central controller, or remote host identifies the player, the central server, central controller, or remote host enables placement of one or more wagers on one or more plays of one or more primary or base games and/or one or more secondary or bonus games, and displays those plays via the Internet browser of the EGM (or personal gaming device). Examples of implementations of Internet-based gaming are further described in U.S. Pat. No. 8,764,566, entitled “Internet Remote Game Server,” and U.S. Pat. No. 8,147,334, entitled “Universal Game Server”.
The central server, central controller, or remote host and the EGM (or personal gaming device) are configured to connect to the data network or remote communications link in any suitable manner. In various embodiments, such a connection is accomplished via: a conventional phone line or other data transmission line, a digital subscriber line (DSL), a T-1 line, a coaxial cable, a fiber optic cable, a wireless or wired routing device, a mobile communications network connection (such as a cellular network or mobile Internet network), or any other suitable medium. The expansion in the quantity of computing devices and the quantity and speed of Internet connections in recent years increases opportunities for players to use a variety of EGMs (or personal gaming devices) to play games from an ever-increasing quantity of remote sites. Additionally, the enhanced bandwidth of digital wireless communications may render such technology suitable for some or all communications, particularly if such communications are encrypted. Higher data transmission speeds may be useful for enhancing the sophistication and response of the display and interaction with players.

As generally described above, in certain embodiments, such as the example EGMs 2000a and 2000b illustrated in
In certain embodiments, the EGM is a device that has obtained approval from a regulatory gaming commission, and in other embodiments, the EGM is a device that has not obtained approval from a regulatory gaming commission.
The EGMs described above are merely three examples of different types of EGMs. Certain of these example EGMs may include one or more elements that may not be included in all gaming systems, and these example EGMs may not include one or more elements that are included in other gaming systems. For example, certain EGMs include a coin acceptor while others do not.
In various embodiments, an EGM may be implemented in one of a variety of different configurations. In various embodiments, the EGM may be implemented as one of: (a) a dedicated EGM in which computerized game programs executable by the EGM for controlling any primary or base games (referred to herein as “primary games”) and/or any secondary or bonus games or other functions (referred to herein as “secondary games”) displayed by the EGM are provided with the EGM before delivery to a gaming establishment or before being provided to a player; and (b) a changeable EGM in which computerized game programs executable by the EGM for controlling any primary games and/or secondary games displayed by the EGM are downloadable or otherwise transferred to the EGM through a data network or remote communication link; from a USB drive, flash memory card, or other suitable memory device; or in any other suitable manner after the EGM is physically located in a gaming establishment or after the EGM is provided to a player.
As generally explained above, in various embodiments in which the gaming system includes a central server, central controller, or remote host and a changeable EGM, the at least one memory device of the central server, central controller, or remote host stores different game programs and instructions executable by the at least one processor of the changeable EGM to control one or more primary games and/or secondary games displayed by the changeable EGM. More specifically, each such executable game program represents a different game or a different type of game that the at least one changeable EGM is configured to operate. In one example, certain of the game programs are executable by the changeable EGM to operate games having the same or substantially the same game play but different paytables. In different embodiments, each executable game program is associated with a primary game, a secondary game, or both. In certain embodiments, an executable game program is executable by the at least one processor of the at least one changeable EGM as a secondary game to be played simultaneously with a play of a primary game (which may be downloaded to or otherwise stored on the at least one changeable EGM), or vice versa.
In operation of such embodiments, the central server, central controller, or remote host is configured to communicate one or more of the stored executable game programs to the at least one processor of the changeable EGM. In different embodiments, a stored executable game program is communicated or delivered to the at least one processor of the changeable EGM by: (a) embedding the executable game program in a device or a component (such as a microchip to be inserted into the changeable EGM); (b) writing the executable game program onto a disc or other media; or (c) uploading or streaming the executable game program over a data network (such as a dedicated data network). After the executable game program is communicated from the central server, central controller, or remote host to the changeable EGM, the at least one processor of the changeable EGM executes the executable game program to enable the primary game and/or the secondary game associated with that executable game program to be played using the display device(s) and/or the input device(s) of the changeable EGM. That is, when an executable game program is communicated to the at least one processor of the changeable EGM, the at least one processor of the changeable EGM changes the game or the type of game that may be played using the changeable EGM.
In certain embodiments, the gaming system randomly determines any game outcome(s) (such as a win outcome) and/or award(s) (such as a quantity of credits to award for the win outcome) for a play of a primary game and/or a play of a secondary game based on probability data. In certain such embodiments, this random determination is provided through utilization of an RNG, such as a true RNG or a pseudo RNG, or any other suitable randomization process. In one such embodiment, each game outcome or award is associated with a probability, and the gaming system generates the game outcome(s) and/or the award(s) to be provided based on the associated probabilities. In these embodiments, since the gaming system generates game outcomes and/or awards randomly or based on one or more probability calculations, there is no certainty that the gaming system will ever provide any specific game outcome and/or award.
In certain embodiments, the gaming system maintains one or more predetermined pools or sets of predetermined game outcomes and/or awards. In certain such embodiments, upon generation or receipt of a game outcome and/or award request, the gaming system independently selects one of the predetermined game outcomes and/or awards from the one or more pools or sets. The gaming system flags or marks the selected game outcome and/or award as used. Once a game outcome or an award is flagged as used, it is prevented from further selection from its respective pool or set; that is, the gaming system does not select that game outcome or award upon another game outcome and/or award request. The gaming system provides the selected game outcome and/or award. Examples of this type of award evaluation are described in U.S. Pat. No. 7,470,183, entitled “Finite Pool Gaming Method and Apparatus”; U.S. Pat. No. 7,563,163, entitled “Gaming Device Including Outcome Pools for Providing Game Outcomes”; U.S. Pat. No. 7,833,092, entitled “Method and System for Compensating for Player Choice in a Game of Chance”; U.S. Pat. No. 8,070,579, entitled “Bingo System with Downloadable Common Patterns”; and U.S. Pat. No. 8,398,472, entitled “Central Determination Poker Game”.
In certain embodiments, the gaming system determines a predetermined game outcome and/or award based on the results of a bingo, keno, or lottery game. In certain such embodiments, the gaming system utilizes one or more bingo, keno, or lottery games to determine the predetermined game outcome and/or award provided for a primary game and/or a secondary game. The gaming system is provided or associated with a bingo card. Each bingo card consists of a matrix or array of elements, wherein each element is designated with separate indicia. After a bingo card is provided, the gaming system randomly selects or draws a plurality of the elements. As each element is selected, a determination is made as to whether the selected element is present on the bingo card. If the selected element is present on the bingo card, that selected element on the provided bingo card is marked or flagged. This process of selecting elements and marking any selected elements on the provided bingo cards continues until one or more predetermined patterns are marked on one or more of the provided bingo cards. After one or more predetermined patterns are marked on one or more of the provided bingo cards, game outcome and/or award is determined based, at least in part, on the selected elements on the provided bingo cards. Examples of this type of award determination are described in U.S. Pat. No. 7,753,774, entitled “Using Multiple Bingo Cards to Represent Multiple Slot Paylines and Other Class III Game Options”; U.S. Pat. No. 7,731,581, entitled “Multi-Player Bingo Game with Multiple Alternative Outcome Displays”; U.S. Pat. No. 7,955,170, entitled “Providing Non-Bingo Outcomes for a Bingo Game”; U.S. Pat. No. 8,070,579, entitled “Bingo System with Downloadable Common Patterns”; and U.S. Pat. No. 8,500,538, entitled “Bingo Gaming System and Method for Providing Multiple Outcomes from Single Bingo Pattern”.
In certain embodiments in which the gaming system includes a central server, central controller, or remote host and an EGM, the EGM is configured to communicate with the central server, central controller, or remote host for monitoring purposes only. In such embodiments, the EGM determines the game outcome(s) and/or award(s) to be provided in any of the manners described above, and the central server, central controller, or remote host monitors the activities and events occurring on the EGM. In one such embodiment, the gaming system includes a real-time or online accounting and gaming information system configured to communicate with the central server, central controller, or remote host. In this embodiment, the accounting and gaming information system includes: (a) a player database configured to store player profiles, (b) a player tracking module configured to track players (as described below), and (c) a credit system configured to provide automated transactions. Examples of such accounting systems are described in U.S. Pat. No. 6,913,534, entitled “Gaming Machine Having a Lottery Game and Capability for Integration with Gaming Device Accounting System and Player Tracking System,” and U.S. Pat. No. 8,597,116, entitled “Virtual Player Tracking and Related Services”.
As noted above, in various embodiments, the gaming system includes one or more executable game programs executable by at least one processor of the gaming system to provide one or more primary games and one or more secondary games. The primary game(s) and the secondary game(s) may comprise any suitable games and/or wagering games, such as, but not limited to: electro-mechanical or video slot or spinning reel type games; video card games such as video draw poker, multi-hand video draw poker, other video poker games, video blackjack games, and video baccarat games; video keno games; video bingo games; and video selection games.
In certain embodiments in which the primary game is a slot or spinning reel type game, the gaming system includes one or more reels in either an electromechanical form with mechanical rotating reels or in a video form with simulated reels and movement thereof. Each reel displays a plurality of indicia or symbols, such as bells, hearts, fruits, numbers, letters, bars, or other images that typically correspond to a theme associated with the gaming system. In certain such embodiments, the gaming system includes one or more paylines associated with the reels. In certain embodiments, one or more of the reels are independent reels or unisymbol reels. In such embodiments, each independent reel generates and displays one symbol.
In various embodiments, one or more of the paylines is horizontal, vertical, circular, diagonal, angled, or any suitable combination thereof. In other embodiments, each of one or more of the paylines is associated with a plurality of adjacent symbol display areas on a requisite number of adjacent reels. In one such embodiment, one or more paylines are formed between at least two symbol display areas that are adjacent to each other by either sharing a common side or sharing a common corner (i.e., such paylines are connected paylines). The gaming system enables a wager to be placed on one or more of such paylines to activate such paylines. In other embodiments in which one or more paylines are formed between at least two adjacent symbol display areas, the gaming system enables a wager to be placed on a plurality of symbol display areas, which activates those symbol display areas.
In various embodiments, the gaming system provides one or more awards after a spin of the reels when specified types and/or configurations of the indicia or symbols on the reels occur on an active payline or otherwise occur in a winning pattern, occur on the requisite number of adjacent reels, and/or occur in a scatter pay arrangement.
In certain embodiments, the gaming system employs a ways to win award determination. In these embodiments, any outcome to be provided is determined based on a number of associated symbols that are generated in active symbol display areas on the requisite number of adjacent reels (i.e., not on paylines passing through any displayed winning symbol combinations). If a winning symbol combination is generated on the reels, one award for that occurrence of the generated winning symbol combination is provided. Examples of ways to win award determinations are described in U.S. Pat. No. 8,012,011, entitled “Gaming Device and Method Having Independent Reels and Multiple Ways of Winning”; U.S. Pat. No. 8,241,104, entitled “Gaming Device and Method Having Designated Rules for Determining Ways To Win”; and U.S. Pat. No. 8,430,739, entitled “Gaming System and Method Having Wager Dependent Different Symbol Evaluations”.
In various embodiments, the gaming system includes a progressive award. Typically, a progressive award includes an initial amount and an additional amount funded through a portion of each wager placed to initiate a play of a primary game. When one or more triggering events occurs, the gaming system provides at least a portion of the progressive award. After the gaming system provides the progressive award, an amount of the progressive award is reset to the initial amount and a portion of each subsequent wager is allocated to the next progressive award. Examples of progressive gaming systems are described in U.S. Pat. No. 7,585,223, entitled “Server Based Gaming System Having Multiple Progressive Awards”; U.S. Pat. No. 7,651,392, entitled “Gaming Device System Having Partial Progressive Payout”; U.S. Pat. No. 7,666,093, entitled “Gaming Method and Device Involving Progressive Wagers”; U.S. Pat. No. 7,780,523, entitled “Server Based Gaming System Having Multiple Progressive Awards”; and U.S. Pat. No. 8,337,298, entitled “Gaming Device Having Multiple Different Types of Progressive Awards”.
As generally noted above, in addition to providing winning credits or other awards for one or more plays of the primary game(s), in various embodiments the gaming system provides credits or other awards for one or more plays of one or more secondary games. The secondary game typically enables an award to be obtained addition to any award obtained through play of the primary game(s). The secondary game(s) typically produces a higher level of player excitement than the primary game(s) because the secondary game(s) provides a greater expectation of winning than the primary game(s) and is accompanied with more attractive or unusual features than the primary game(s). The secondary game(s) may be any type of suitable game, either similar to or completely different from the primary game.
In various embodiments, the gaming system automatically provides or initiates the secondary game upon the occurrence of a triggering event or the satisfaction of a qualifying condition. In other embodiments, the gaming system initiates the secondary game upon the occurrence of the triggering event or the satisfaction of the qualifying condition and upon receipt of an initiation input. In certain embodiments, the triggering event or qualifying condition is a selected outcome in the primary game(s) or a particular arrangement of one or more indicia on a display device for a play of the primary game(s), such as a “BONUS” symbol appearing on three adjacent reels along a payline following a spin of the reels for a play of the primary game. In other embodiments, the triggering event or qualifying condition occurs based on a certain amount of game play (such as number of games, number of credits, amount of time) being exceeded, or based on a specified number of points being earned during game play. Any suitable triggering event or qualifying condition or any suitable combination of a plurality of different triggering events or qualifying conditions may be employed.
In other embodiments, at least one processor of the gaming system randomly determines when to provide one or more plays of one or more secondary games. In one such embodiment, no apparent reason is provided for providing the secondary game. In this embodiment, qualifying for a secondary game is not triggered by the occurrence of an event in any primary game or based specifically on any of the plays of any primary game. That is, qualification is provided without any explanation or, alternatively, with a simple explanation. In another such embodiment, the gaming system determines qualification for a secondary game at least partially based on a game triggered or symbol triggered event, such as at least partially based on play of a primary game.
In various embodiments, after qualification for a secondary game has been determined, the secondary game participation may be enhanced through continued play on the primary game. Thus, in certain embodiments, for each secondary game qualifying event, such as a secondary game symbol, that is obtained, a given number of secondary game wagering points or credits is accumulated in a “secondary game meter” configured to accrue the secondary game wagering credits or entries toward eventual participation in the secondary game. In one such embodiment, the occurrence of multiple such secondary game qualifying events in the primary game results in an arithmetic or exponential increase in the number of secondary game wagering credits awarded. In another such embodiment, any extra secondary game wagering credits may be redeemed during the secondary game to extend play of the secondary game.
In certain embodiments, no separate entry fee or buy-in for the secondary game is required. That is, entry into the secondary game cannot be purchased; rather, in these embodiments entry must be won or earned through play of the primary game, thereby encouraging play of the primary game. In other embodiments, qualification for the secondary game is accomplished through a simple “buy-in.” For example, qualification through other specified activities is unsuccessful, payment of a fee or placement of an additional wager “buys-in” to the secondary game. In certain embodiments, a separate side wager must be placed on the secondary game or a wager of a designated amount must be placed on the primary game to enable qualification for the secondary game. In these embodiments, the secondary game triggering event must occur and the side wager (or designated primary game wager amount) must have been placed for the secondary game to trigger.
In various embodiments in which the gaming system includes a plurality of EGMs, the EGMs are configured to communicate with one another to provide a group gaming environment. In certain such embodiments, the EGMs enable players of those EGMs to work in conjunction with one another, such as by enabling the players to play together as a team or group, to win one or more awards. In other such embodiments, the EGMs enable players of those EGMs to compete against one another for one or more awards. In one such embodiment, the EGMs enable the players of those EGMs to participate in one or more gaming tournaments for one or more awards. Examples of group gaming systems are described in U.S. Pat. No. 8,070,583, entitled “Server Based Gaming System and Method for Selectively Providing One or More Different Tournaments”; U.S. Pat. No. 8,500,548, entitled “Gaming System and Method for Providing Team Progressive Awards”; and U.S. Pat. No. 8,562,423, entitled “Method and Apparatus for Rewarding Multiple Game Players for a Single Win”.
In various embodiments, the gaming system includes one or more player tracking systems. Such player tracking systems enable operators of the gaming system (such as casinos or other gaming establishments) to recognize the value of customer loyalty by identifying frequent customers and rewarding them for their patronage. Such a player tracking system is configured to track a player's gaming activity. In one such embodiment, the player tracking system does so through the use of player tracking cards. In this embodiment, a player is issued a player identification card that has an encoded player identification number that uniquely identifies the player. When the player's playing tracking card is inserted into a card reader of the gaming system to begin a gaming session, the card reader reads the player identification number off the player tracking card to identify the player. The gaming system timely tracks any suitable information or data relating to the identified player's gaming session. The gaming system also timely tracks when the player tracking card is removed to conclude play for that gaming session. In another embodiment, rather than requiring insertion of a player tracking card into the card reader, the gaming system utilizes one or more portable devices, such as a mobile phone, a radio frequency identification tag, or any other suitable wireless device, to track when a gaming session begins and ends. In another embodiment, the gaming system utilizes any suitable biometric technology or ticket technology to track when a gaming session begins and ends.
In such embodiments, during one or more gaming sessions, the gaming system tracks any suitable information or data, such as any amounts wagered, average wager amounts, and/or the time at which these wagers are placed. In different embodiments, for one or more players, the player tracking system includes the player's account number, the player's card number, the player's first name, the player's surname, the player's preferred name, the player's player tracking ranking, any promotion status associated with the player's player tracking card, the player's address, the player's birthday, the player's anniversary, the player's recent gaming sessions, or any other suitable data. In various embodiments, such tracked information and/or any suitable feature associated with the player tracking system is displayed on a player tracking display. In various embodiments, such tracked information and/or any suitable feature associated with the player tracking system is displayed via one or more service windows that are displayed on the central display device and/or the upper display device. Examples of player tracking systems are described in U.S. Pat. No. 6,722,985, entitled “Universal Player Tracking System”; U.S. Pat. No. 6,908,387, entitled “Player Tracking Communication Mechanisms in a Gaming Machine”; U.S. Pat. No. 7,311,605, entitled “Player Tracking Assembly for Complete Patron Tracking for Both Gaming and Non-Gaming Casino Activity”; U.S. Pat. No. 7,611,411, entitled “Player Tracking Instruments Having Multiple Communication Modes”; U.S. Pat. No. 7,617,151, entitled “Alternative Player Tracking Techniques”; and U.S. Pat. No. 8,057,298, entitled “Virtual Player Tracking and Related Services”.
In various embodiments, the gaming system includes one or more servers configured to communicate with a personal gaming device—such as a smartphone, a tablet computer, a desktop computer, or a laptop computer—to enable web-based game play using the personal gaming device. In various embodiments, the player must first access a gaming website via an Internet browser of the personal gaming device or execute an application (commonly called an “app”) installed on the personal gaming device before the player can use the personal gaming device to participate in web-based game play. In certain embodiments, the one or more servers and the personal gaming device operate in a thin-client environment. In these embodiments, the personal gaming device receives inputs via one or more input devices (such as a touch screen and/or physical buttons), the personal gaming device sends the received inputs to the one or more servers, the one or more servers make various determinations based on the inputs and determine content to be displayed (such as a randomly determined game outcome and corresponding award), the one or more servers send the content to the personal gaming device, and the personal gaming device displays the content.
In certain such embodiments, the one or more servers must identify the player before enabling game play on the personal gaming device (or, in some embodiments, before enabling monetary wager-based game play on the personal gaming device). In these embodiments, the player must identify herself to the one or more servers, such as by inputting the player's unique player name and password combination, providing an input to a biometric sensor (e.g., a fingerprint sensor, a retinal sensor, a voice sensor, or a facial-recognition sensor), or providing any other suitable information.
Once identified, the one or more servers enable the player to establish an account balance from which the player can draw credits usable to wager on plays of a game. In certain embodiments, the one or more servers enable the player to initiate an electronic funds transfer to transfer funds from a bank account to the player's account balance. In other embodiments, the one or more servers enable the player to make a payment using the player's credit card, debit card, or other suitable device to add money to the player's account balance. In other embodiments, the one or more servers enable the player to add money to the player's account balance via a peer-to-peer type application, such as PayPal or Venmo. The one or more servers also enable the player to cash out the player's account balance (or part of it) in any suitable manner, such as via an electronic funds transfer, by initiating creation of a paper check that is mailed to the player, or by initiating printing of a voucher at a kiosk in a gaming establishment.
In certain embodiments, the one or more servers include a payment server that handles establishing and cashing out players' account balances and a separate game server configured to determine the outcome and any associated award for a play of a game. In these embodiments, the game server is configured to communicate with the personal gaming device and the payment device, and the personal gaming device and the payment device are not configured to directly communicate with one another. In these embodiments, when the game server receives data representing a request to start a play of a game at a desired wager, the game server sends data representing the desired wager to the payment server. The payment server determines whether the player's account balance can cover the desired wager (i.e., includes a monetary balance at least equal to the desired wager).
If the payment server determines that the player's account balance cannot cover the desired wager, the payment server notifies the game server, which then instructs the personal gaming device to display a suitable notification to the player that the player's account balance is too low to place the desired wager. If the payment server determines that the player's account balance can cover the desired wager, the payment server deducts the desired wager from the account balance and notifies the game server. The game server then determines an outcome and any associated award for the play of the game. The game server notifies the payment server of any nonzero award, and the payment server increases the player's account balance by the nonzero award. The game server sends data representing the outcome and any award to the personal gaming device, which displays the outcome and any award.
In certain embodiments, the one or more servers enable web-based game play using a personal gaming device only if the personal gaming device satisfies one or more jurisdictional requirements. In one embodiment, the one or more servers enable web-based game play using the personal gaming device only if the personal gaming device is located within a designated geographic area (such as within certain state or county lines or within the boundaries of a gaming establishment). In this embodiment, the geolocation module of the personal gaming device determines the location of the personal gaming device and sends the location to the one or more servers, which determine whether the personal gaming device is located within the designated geographic area. In various embodiments, the one or more servers enable non-monetary wager-based game play if the personal gaming device is located outside of the designated geographic area.
In various embodiments, the gaming system includes an EGM configured to communicate with a personal gaming device—such as a smartphone, a tablet computer, a desktop computer, or a laptop computer—to enable tethered mobile game play using the personal gaming device. Generally, in these embodiments, the EGM establishes communication with the personal gaming device and enables the player to play games on the EGM remotely via the personal gaming device. In certain embodiments, the gaming system includes a geo-fence system that enables tethered game play within a particular geographic area but not outside of that geographic area. Examples of tethering an EGM to a personal gaming device and geo-fencing are described in U.S. Patent Appl. Pub. No. 2013/0267324, entitled “Remote Gaming Method Allowing Temporary Inactivation Without Terminating Playing Session Due to Game Inactivity”.
In certain embodiments, the gaming system is configured to communicate with a social network server that hosts or partially hosts a social networking website via a data network (such as the Internet) to integrate a player's gaming experience with the player's social networking account. This enables the gaming system to send certain information to the social network server that the social network server can use to create content (such as text, an image, and/or a video) and post it to the player's wall, newsfeed, or similar area of the social networking website accessible by the player's connections (and in certain cases the public) such that the player's connections can view that information. This also enables the gaming system to receive certain information from the social network server, such as the player's likes or dislikes or the player's list of connections. In certain embodiments, the gaming system enables the player to link the player's player account to the player's social networking account(s). This enables the gaming system to, once it identifies the player and initiates a gaming session (such as via the player logging in to a website (or an application) on the player's personal gaming device or via the player inserting the player's player tracking card into an EGM), link that gaming session to the player's social networking account(s). In other embodiments, the gaming system enables the player to link the player's social networking account(s) to individual gaming sessions when desired by providing the required login information.
For instance, in one embodiment, if a player wins a particular award (e.g., a progressive award or a jackpot award) or an award that exceeds a certain threshold (e.g., an award exceeding $1,000), the gaming system sends information about the award to the social network server to enable the server to create associated content (such as a screenshot of the outcome and associated award) and to post that content to the player's wall (or other suitable area) of the social networking website for the player's connections to see (and to entice them to play). In another embodiment, if a player joins a multiplayer game and there is another seat available, the gaming system sends that information to the social network sever to enable the server to create associated content (such as text indicating a vacancy for that particular game) and to post that content to the player's wall (or other suitable area) of the social networking website for the player's connections to see (and to entice them to fill the vacancy). In another embodiment, if the player consents, the gaming system sends advertisement information or offer information to the social network server to enable the social network server to create associated content (such as text or an image reflecting an advertisement and/or an offer) and to post that content to the player's wall (or other suitable area) of the social networking website for the player's connections to see. In another embodiment, the gaming system enables the player to recommend a game to the player's connections by posting a recommendation to the player's wall (or other suitable area) of the social networking website.
Certain of the gaming systems described herein, such as EGMs located in a casino or another gaming establishment, include certain components and/or are configured to operate in certain manners that differentiate these systems from general purpose computing devices, i.e., certain personal gaming devices such as desktop computers and laptop computers.
For instance, EGMs are highly regulated to ensure fairness and, in many cases, EGMs are configured to award monetary awards up to multiple millions of dollars. To satisfy security and regulatory requirements in a gaming environment, hardware and/or software architectures are implemented in EGMs that differ significantly from those of general purpose computing devices. For purposes of illustration, a description of EGMs relative to general purpose computing devices and some examples of these additional (or different) hardware and/or software architectures found in EGMs are described below.
At first glance, one might think that adapting general purpose computing device technologies to the gaming industry and EGMs would be a simple proposition because both general purpose computing devices and EGMs employ processors that control a variety of devices. However, due to at least: (1) the regulatory requirements placed on EGMs, (2) the harsh environment in which EGMs operate, (3) security requirements, and (4) fault tolerance requirements, adapting general purpose computing device technologies to EGMs can be quite difficult. Further, techniques and methods for solving a problem in the general purpose computing device industry, such as device compatibility and connectivity issues, might not be adequate in the gaming industry. For instance, a fault or a weakness tolerated in a general purpose computing device, such as security holes in software or frequent crashes, is not tolerated in an EGM because in an EGM these faults can lead to a direct loss of funds from the EGM, such as stolen cash or loss of revenue when the EGM is not operating properly or when the random outcome determination is manipulated.
Certain differences between general purpose computing devices and EGMs are described below. A first difference between EGMs and general purpose computing devices is that EGMs are state-based systems. A state-based system stores and maintains its current state in a non-volatile memory such that, in the event of a power failure or other malfunction, the state-based system can return to that state when the power is restored or the malfunction is remedied. For instance, for a state-based EGM, if the EGM displays an award for a game of chance but the power to the EGM fails before the EGM provides the award to the player, the EGM stores the pre-power failure state in a non-volatile memory, returns to that state upon restoration of power, and provides the award to the player. This requirement affects the software and hardware design on EGMs. General purpose computing devices are not state-based machines, and a majority of data is usually lost when a malfunction occurs on a general purpose computing device.
A second difference between EGMs and general purpose computing devices is that, for regulatory purposes, the software on the EGM utilized to operate the EGM has been designed to be static and monolithic to prevent cheating by the operator of the EGM. For instance, one solution that has been employed in the gaming industry to prevent cheating and to satisfy regulatory requirements has been to manufacture an EGM that can use a proprietary processor running instructions to provide the game of chance from an EPROM or other form of non-volatile memory. The coding instructions on the EPROM are static (non-changeable) and must be approved by a gaming regulators in a particular jurisdiction and installed in the presence of a person representing the gaming jurisdiction. Any changes to any part of the software required to generate the game of chance, such as adding a new device driver used to operate a device during generation of the game of chance, can require burning a new EPROM approved by the gaming jurisdiction and reinstalling the new EPROM on the EGM in the presence of a gaming regulator. Regardless of whether the EPROM solution is used, to gain approval in most gaming jurisdictions, an EGM must demonstrate sufficient safeguards that prevent an operator or a player of an EGM from manipulating the EGM's hardware and software in a manner that gives him an unfair, and in some cases illegal, advantage.
A third difference between EGMs and general purpose computing devices is authentication-EGMs storing code are configured to authenticate the code to determine if the code is unaltered before executing the code. If the code has been altered, the EGM prevents the code from being executed. The code authentication requirements in the gaming industry affect both hardware and software designs on EGMs. Certain EGMs use hash functions to authenticate code. For instance, one EGM stores game program code, a hash function, and an authentication hash (which may be encrypted). Before executing the game program code, the EGM hashes the game program code using the hash function to obtain a result hash and compares the result hash to the authentication hash. If the result hash matches the authentication hash, the EGM determines that the game program code is valid and executes the game program code. If the result hash does not match the authentication hash, the EGM determines that the game program code has been altered (i.e., may have been tampered with) and prevents execution of the game program code. Examples of EGM code authentication are described in U.S. Pat. No. 6,962,530, entitled “Authentication in a Secure Computerized Gaming System”; U.S. Pat. No. 7,043,641, entitled “Encryption in a Secure Computerized Gaming System”; U.S. Pat. No. 7,201,662, entitled “Method and Apparatus for Software Authentication”; and U.S. Pat. No. 8,627,097, entitled “System and Method Enabling Parallel Processing of Hash Functions Using Authentication Checkpoint Hashes”.
A fourth difference between EGMs and general purpose computing devices is that EGMs have unique peripheral device requirements that differ from those of a general purpose computing device, such as peripheral device security requirements not usually addressed by general purpose computing devices. For instance, monetary devices, such as coin dispensers, bill validators, and ticket printers and computing devices that are used to govern the input and output of cash or other items having monetary value (such as tickets) to and from an EGM have security requirements that are not typically addressed in general purpose computing devices. Therefore, many general purpose computing device techniques and methods developed to facilitate device connectivity and device compatibility do not address the emphasis placed on security in the gaming industry.
To address some of the issues described above, a number of hardware/software components and architectures are utilized in EGMs that are not typically found in general purpose computing devices. These hardware/software components and architectures, as described below in more detail, include but are not limited to watchdog timers, voltage monitoring systems, state-based software architecture and supporting hardware, specialized communication interfaces, security monitoring, and trusted memory.
Certain EGMs use a watchdog timer to provide a software failure detection mechanism. In a normally-operating EGM, the operating software periodically accesses control registers in the watchdog timer subsystem to “re-trigger” the watchdog. Should the operating software fail to access the control registers within a preset timeframe, the watchdog timer will timeout and generate a system reset. Typical watchdog timer circuits include a loadable timeout counter register to enable the operating software to set the timeout interval within a certain range of time. A differentiating feature of some circuits is that the operating software cannot completely disable the function of the watchdog timer. In other words, the watchdog timer always functions from the time power is applied to the board.
Certain EGMs use several power supply voltages to operate portions of the computer circuitry. These can be generated in a central power supply or locally on the computer board. If any of these voltages falls out of the tolerance limits of the circuitry they power, unpredictable operation of the EGM may result. Though most modern general purpose computing devices include voltage monitoring circuitry, these types of circuits only report voltage status to the operating software. Out of tolerance voltages can cause software malfunction, creating a potential uncontrolled condition in the general purpose computing device. Certain EGMs have power supplies with relatively tighter voltage margins than that required by the operating circuitry. In addition, the voltage monitoring circuitry implemented in certain EGMs typically has two thresholds of control. The first threshold generates a software event that can be detected by the operating software and an error condition then generated. This threshold is triggered when a power supply voltage falls out of the tolerance range of the power supply, but is still within the operating range of the circuitry. The second threshold is set when a power supply voltage falls out of the operating tolerance of the circuitry. In this case, the circuitry generates a reset, halting operation of the EGM.
As described above, certain EGMs are state-based machines. Different functions of the game provided by the EGM (e.g., bet, play, result, points in the graphical presentation, etc.) may be defined as a state. When the EGM moves a game from one state to another, the EGM stores critical data regarding the game software in a custom non-volatile memory subsystem. This ensures that the player's wager and credits are preserved and to minimize potential disputes in the event of a malfunction on the EGM. In general, the EGM does not advance from a first state to a second state until critical information that enables the first state to be reconstructed has been stored. This feature enables the EGM to recover operation to the current state of play in the event of a malfunction, loss of power, etc. that occurred just before the malfunction. In at least one embodiment, the EGM is configured to store such critical information using atomic transactions.
Generally, an atomic operation in computer science refers to a set of operations that can be combined so that they appear to the rest of the system to be a single operation with only two possible outcomes: success or failure. As related to data storage, an atomic transaction may be characterized as series of database operations which either all occur, or all do not occur. A guarantee of atomicity prevents updates to the database occurring only partially, which can result in data corruption.
To ensure the success of atomic transactions relating to critical information to be stored in the EGM memory before a failure event (e.g., malfunction, loss of power, etc.), memory that includes one or more of the following criteria be used: direct memory access capability; data read/write capability which meets or exceeds minimum read/write access characteristics (such as at least 5.08 Mbytes/sec (Read) and/or at least 38.0 Mbytes/sec (Write)). Memory devices that meet or exceed the above criteria may be referred to as “fault-tolerant” memory devices.
Typically, battery-backed RAM devices may be configured to function as fault-tolerant devices according to the above criteria, whereas flash RAM and/or disk drive memory are typically not configurable to function as fault-tolerant devices according to the above criteria. Accordingly, battery-backed RAM devices are typically used to preserve EGM critical data, although other types of non-volatile memory devices may be employed. These memory devices are typically not used in typical general purpose computing devices.
Thus, in at least one embodiment, the EGM is configured to store critical information in fault-tolerant memory (e.g., battery-backed RAM devices) using atomic transactions. Further, in at least one embodiment, the fault-tolerant memory is able to successfully complete all desired atomic transactions (e.g., relating to the storage of EGM critical information) within a time period of 200 milliseconds or less. In at least one embodiment, the time period of 200 milliseconds represents a maximum amount of time for which sufficient power may be available to the various EGM components after a power outage event has occurred at the EGM.
As described previously, the EGM may not advance from a first state to a second state until critical information that enables the first state to be reconstructed has been atomically stored. After the state of the EGM is restored during the play of a game of chance, game play may resume and the game may be completed in a manner that is no different than if the malfunction had not occurred. Thus, for example, when a malfunction occurs during a game of chance, the EGM may be restored to a state in the game of chance just before when the malfunction occurred. The restored state may include metering information and graphical information that was displayed on the EGM in the state before the malfunction. For example, when the malfunction occurs during the play of a card game after the cards have been dealt, the EGM may be restored with the cards that were previously displayed as part of the card game. As another example, a bonus game may be triggered during the play of a game of chance in which a player is required to make a number of selections on a video display screen. When a malfunction has occurred after the player has made one or more selections, the EGM may be restored to a state that shows the graphical presentation just before the malfunction including an indication of selections that have already been made by the player. In general, the EGM may be restored to any state in a plurality of states that occur in the game of chance that occurs while the game of chance is played or to states that occur between the play of a game of chance.
Game history information regarding previous games played such as an amount wagered, the outcome of the game, and the like may also be stored in a non-volatile memory device. The information stored in the non-volatile memory may be detailed enough to reconstruct a portion of the graphical presentation that was previously presented on the EGM and the state of the EGM (e.g., credits) at the time the game of chance was played. The game history information may be utilized in the event of a dispute. For example, a player may decide that in a previous game of chance that they did not receive credit for an award that they believed they won. The game history information may be used to reconstruct the state of the EGM before, during, and/or after the disputed game to demonstrate whether the player was correct or not in the player's assertion. Examples of a state-based EGM, recovery from malfunctions, and game history are described in U.S. Pat. No. 6,804,763, entitled “High Performance Battery Backed RAM Interface”; U.S. Pat. No. 6,863,608, entitled “Frame Capture of Actual Game Play”; U.S. Pat. No. 7,111,141, entitled “Dynamic NV-RAM”; and U.S. Pat. No. 7,384,339, entitled, “Frame Capture of Actual Game Play”.
Another feature of EGMs is that they often include unique interfaces, including serial interfaces, to connect to specific subsystems internal and external to the EGM. The serial devices may have electrical interface requirements that differ from the “standard” EIA serial interfaces provided by general purpose computing devices. These interfaces may include, for example, Fiber Optic Serial, optically coupled serial interfaces, current loop style serial interfaces, etc. In addition, to conserve serial interfaces internally in the EGM, serial devices may be connected in a shared, daisy-chain fashion in which multiple peripheral devices are connected to a single serial channel.
The serial interfaces may be used to transmit information using communication protocols that are unique to the gaming industry. For example, IGT's Netplex is a proprietary communication protocol used for serial communication between EGMs. As another example, SAS is a communication protocol used to transmit information, such as metering information, from an EGM to a remote device. Often SAS is used in conjunction with a player tracking system.
Certain EGMs may alternatively be treated as peripheral devices to a casino communication controller and connected in a shared daisy chain fashion to a single serial interface. In both cases, the peripheral devices are assigned device addresses. If so, the serial controller circuitry must implement a method to generate or detect unique device addresses. General purpose computing device serial ports are not able to do this.
Security monitoring circuits detect intrusion into an EGM by monitoring security switches attached to access doors in the EGM cabinet. Access violations result in suspension of game play and can trigger additional security operations to preserve the current state of game play. These circuits also function when power is off by use of a battery backup. In power-off operation, these circuits continue to monitor the access doors of the EGM. When power is restored, the EGM can determine whether any security violations occurred while power was off, e.g., via software for reading status registers. This can trigger event log entries and further data authentication operations by the EGM software.
Trusted memory devices and/or trusted memory sources are included in an EGM to ensure the authenticity of the software that may be stored on less secure memory subsystems, such as mass storage devices. Trusted memory devices and controlling circuitry are typically designed to not enable modification of the code and data stored in the memory device while the memory device is installed in the EGM. The code and data stored in these devices may include authentication algorithms, random number generators, authentication keys, operating system kernels, etc. The purpose of these trusted memory devices is to provide gaming regulatory authorities a root trusted authority within the computing environment of the EGM that can be tracked and verified as original. This may be accomplished via removal of the trusted memory device from the EGM computer and verification of the secure memory device contents is a separate third party verification device. Once the trusted memory device is verified as authentic, and based on the approval of the verification algorithms included in the trusted device, the EGM is enabled to verify the authenticity of additional code and data that may be located in the gaming computer assembly, such as code and data stored on hard disk drives. Examples of trusted memory devices are described in U.S. Pat. No. 6,685,567, entitled “Process Verification”.
In at least one embodiment, at least a portion of the trusted memory devices/sources may correspond to memory that cannot easily be altered (e.g., “unalterable memory”) such as EPROMS, PROMS, Bios, Extended Bios, and/or other memory sources that are able to be configured, verified, and/or authenticated (e.g., for authenticity) in a secure and controlled manner.
According to one embodiment, when a trusted information source is in communication with a remote device via a network, the remote device may employ a verification scheme to verify the identity of the trusted information source. For example, the trusted information source and the remote device may exchange information using public and private encryption keys to verify each other's identities. In another embodiment, the remote device and the trusted information source may engage in methods using zero knowledge proofs to authenticate each of their respective identities.
EGMs storing trusted information may utilize apparatuses or methods to detect and prevent tampering. For instance, trusted information stored in a trusted memory device may be encrypted to prevent its misuse. In addition, the trusted memory device may be secured behind a locked door. Further, one or more sensors may be coupled to the memory device to detect tampering with the memory device and provide some record of the tampering. In yet another example, the memory device storing trusted information might be designed to detect tampering attempts and clear or erase itself when an attempt at tampering has been detected. Examples of trusted memory devices/sources are described in U.S. Pat. No. 7,515,718, entitled “Secured Virtual Network in a Gaming Environment”.
Mass storage devices used in a general purpose computing devices typically enable code and data to be read from and written to the mass storage device. In a gaming environment, modification of the gaming code stored on a mass storage device is strictly controlled and would only be enabled under specific maintenance type events with electronic and physical enablers required. Though this level of security could be provided by software, EGMs that include mass storage devices include hardware level mass storage data protection circuitry that operates at the circuit level to monitor attempts to modify data on the mass storage device and will generate both software and hardware error triggers should a data modification be attempted without the proper electronic and physical enablers being present. Examples of using a mass storage device are described in U.S. Pat. No. 6,149,522, entitled “Method of Authenticating Game Data Sets in an Electronic Casino Gaming System”.
Various changes and modifications to the present embodiments described herein will be apparent to those skilled in the art. Such changes and modifications can be made without departing from the spirit and scope of the present subject matter and without diminishing its intended technical scope. It is therefore intended that such changes and modifications be covered by the appended claims.
This application is a continuation of, claims priority to and the benefit of U.S. patent application Ser. No. 17/662,703, filed on May 10, 2022, the entire contents of which is incorporated herein by reference.
