Patent Application
20110092262
This application is entitled to the benefit of the co-pending patent application entitled “Methods and Devices for Multi-State Card Games with Card Replacement,” with listed inventor Theo Naicker, filed on the same date as this application, and hereby incorporated by reference in its entirety.
In various types of card games, such as but not limited to poker, instead of competing against other participants, a player may compete against a house. The house may be any type of game provider, such as a brick-and-mortar or online casino. The player's goal may be to achieve one of several possible winning hands through a combination of luck and strategy.
The house that provides a card game usually expects a marginal profit on each hand played. In order to achieve this profit, the house may seek to differentiate itself from other game providers by offering new card games, as well as new variations of well-known card games. Players may be relatively indifferent to standard versions of well-known card games, and therefore may find new variations of these card games fresh and exciting in comparison. Exciting card games also tend to encourage repeat play and return visits to the game provider. Thus, house profit is likely to increase when the house provides new variations of known card games.
The methods and devices disclosed herein provide enhancements to card games by giving players an opportunity to exchange their cards at various stages of a card game. These exchanges may result in the player's hand being improved. As a result, players may benefit from finding the card game more enjoyable and therefore may engage in additional gameplay. Some of these exchanges may be associated with a cost to the player. Therefore, the house may also benefit from increased popularity, increased gameplay, more players, and/or a higher profit margin.
In one embodiment, a player engages in a card game such as poker. The player's goal may be to form one of several predetermined winning hands of cards. Each winning hand may be associated with a specific return, or payout, to the player. For instance, a poker hand of three of a kind may return 3-to-1 (that is, the player receives three times his or her wager), while a full house may return 10-to-1. To facilitate the player's wagering, the player may be associated with an account that is either held by the house or by a third party.
Accordingly, the player may be dealt an initial hand of cards from a deck, and may be offered the opportunity to perform a free card replacement cycle of one or more of these cards. If the player chooses to perform the first card replacement cycle, the player may select one or more cards from his or her hand to be replaced, and hold the remaining cards. The selected cards may be discarded and replaced with an equal number of cards drawn from the deck and added to the player's hand. After this optional first replacement, the player may be shown, told, or otherwise determine a first return on his or her hand of cards.
If the player is unsatisfied with this first return, the player may opt to select one or more cards for a second card replacement cycle. However, the player may incur a cost for performing this second cycle. In particular, the cost may be based on the difference between the first return and the expected second return associated with replacing the cards the player has selected for replacement. For instance, based on the cards the player holds, the cards the player selects for replacement, and the overall state of the game, the expected second return can be determined before the second replacement cycle actually takes place.
The cost of the second replacement cycle may be provided to the player, and the player may decide whether to perform the second replacement cycle. If the player decides to perform the second replacement cycle and incur the associated cost, the player's selected cards may be discarded and replaced with new cards drawn from the deck, and the player's account may be debited by the cost. At this point, the game may end with the player being awarded the actual return of the player's hand. Alternatively, the player may be offered one or more additional opportunities to perform additional replacement cycles.
These and other aspects and advantages will become apparent to those of ordinary skill in the art by reading the following detailed description, with reference where appropriate to the accompanying drawings. Further, it should be understood that the foregoing overview is merely for purposes of illustration and is not intended to limit the scope of the invention as claimed.
Card games that provide players with opportunities to improve their hands are presented. Preferably, these opportunities are associated with costs to be incurred by the player, should the player choose to take advantage of the opportunity and replace one or more chosen cards. The costs may be dynamically determined based on the player's expected return once the chosen cards are replaced. The card games disclosed here may be played by humans, either as a table game, or via a computer medium. Alternatively, the card games may be played by a human against a computer opponent, or by two computers.
Herein the term “card game” preferably refers to a single instance or single play of a game such as poker. Thus, a card game may involve a card supply, such as a deck, being shuffled or otherwise randomized, the player engaging in play of the card game, and the card game coming to some form of conclusion. Then the card supply may be re-shuffled prior to the next card game. Alternatively, the player may engage in multiple plays of the card game, each with a respective conclusion, before the card supply is reshuffled.
The embodiments herein are disclosed in the context of card games that preferably take place between a player and a house. These card games may use a standard playing card deck of 52 cards, divided into four suits. These four suits may be, for example, clubs, diamonds, hearts, and spades, or some other type of suit may be used. Therefore, each suit may contain 13 cards, ten of which are preferably labeled with ranks from 1 (ace) to 10, and three of which are preferably face cards with ranks of jack, queen, and king Alternatively, non-standard playing cards may be used as well without departing from the scope of the invention. Additionally, multiple decks of cards may be used as the supply of any cards drawn or dealt.
Typically, these card games allow a player to place a wager at the beginning of each game. Then, the player may engage in the card game in an attempt to achieve a winning hand. The card game may have one or more possible winning hands, and each winning hand is preferably a specific combination of cards that is associated with a return. Preferably, the more difficult it is for the player to achieve the winning hand, the greater the return. Each return may be calculated based at least in part on the player's wager. For instance, the return for a given winning hand may be a particular multiple of the player's wager. If the player does not achieve a winning hand by the end of the card game, the player may lose his or her wager.
In order to facilitate convenient wagering, the player may establish an account for maintaining the player's credit balance. These credits may be or may represent a denomination of money, a representation of money, or items of value that can be exchanged for money. Alternatively, the credits may represent play money and have no actual value, thus allowing players to enjoy the card game without risking actual financial loss. The account may be managed either by the house or a third party, and from time to time the player may load the account with credits via cash payment, credit card, electronic funds transfer, or some other means.
While the embodiments herein may be used with any type of card game played against a house, the embodiments are described in the context of the popular game of poker. It should be understood that poker other types of card games may be played according to a wide variety of rules. For instance, these card games may be played according to house rules of the game provider, or local or regional jurisdictional rules that vary the type of cards used, number of cards per hand, winning hands, returns for each winning hand, or other aspects of gameplay. Accordingly, the embodiments herein may be applied to these alternate rules as well.
Poker typically involves a player initially being dealt five cards from a standard 52-card deck. Alternatively, the player may initially be dealt more or fewer cards from a standard or non-standard deck. The goal of a player in poker may be to achieve a winning hand with a satisfactory return.
Table 1 provides an example listing of winning poker hands in the form of a pay table. Each winning hand is associated with a return. Generally speaking, the more difficult a winning hand is to achieve, the higher the return. Thus, a royal flush, the most difficult winning hand to achieve in Table 1, returns 250 credits for each credit the player wagers. Conversely, one pair, a relatively easy-to-achieve winning hand, returns only one credit for each credit wagered (in other words, the player breaks even when achieving one pair). When evaluating a player's hand against a table, preferably only the best possible winning hand return is awarded to the player. Thus, a hand with three of a kind will only be awarded the return associated with three of a kind rather than the return associated with two of a kind.
It should be understood that the winning hands and returns listed in Table 1 only for purposes of example. Accordingly, additional winning hands as well as different returns, could be used. Furthermore, some winning hands may be further conditioned upon card suit or rank. For instance, the winning hand of one pair may only apply when the pair consists of a rank of jack or higher, and the winning hand of a royal flush may only apply when the five cards are all hearts.
After the player has been dealt an initial hand, the player may be offered the opportunity to replace one or more of the cards in the hand. Replacing cards in a hand may be referred to as performing a card replacement cycle, and may provide the player with a chance to improve the hand.
It should be understood that is makes no difference whether a player selects the cards to be replaced or selects the cards to be held. Since any card not replaced is held and any card not held is replaced, the outcome is the same. Thus, while the following embodiments refer to the player selecting cards to be replaced, the player may actually select the cards to be held, and therefore implicitly also select the cards to be replaced.
In such a situation, the player may be disappointed with breaking even. The player may also be caught up in the gameplay of poker, and willing to incur an additional cost for another chance to achieve a better hand. Accordingly, the house may offer the player one or more additional card replacement cycles for a cost.
Poker, as well as other types of card games, may be enhanced by optional rules providing a player with further opportunities to replace one or more cards in his or her hand. Each card replacement cycle may be associated with a cost, and the cost may be based on the relative advantage that executing the card replacement cycle may provide to the player. By offering additional card replacements, the player's interest in the card game may remain high even if the player is unsatisfied with his or her hand after the first card replacement.
Preferably, the cards selected for replacement in the card selection 210 or the card selection 212 are discarded, and replacement cards are drawn from the deck. These replacement cards may be added to the player's hand, and a cost associated with the combination of selected cards may be debited from the player's account.
Once this second card replacement cycle is complete, the card game may end with the player being awarded a return based on the cards in the player's hand and a pay table such as Table 1. Alternatively, the player may be offered one or more additional card replacement cycles. Thus, the player may continue to replace the cards in his or her hand until he or she is satisfied with the result or has run out of credits. Alternatively, the player may be limited to no more than a given number of card replacement cycles per card game. Each card replacement cycle may involve the player replacing a different number of cards in his or her hand and/or incurring a different cost.
It should be understood that any cards the player discards during a card replacement cycle may be placed in a discard pile. Preferably, cards in the discard pile are not used for the remainder of the card game. After the card game has ended, all cards may be gathered, shuffled or otherwise randomized, and used as a card supply for a subsequent card game.
Regardless of whether the game being played is poker or another card game, each of the card selection 210 and the card selection 212 may be associated with a cost to the player. Preferably, the cost of replacing a particular set of cards is proportional to the expected gain, or a relative advantage, that replacing those cards will provide the player.
In the case of card selection 210, the player has a pair of sevens, which is a winning hand that returns 1-to-1. A pay table, such as the pay table of Table 1, that maps combinations of cards to returns may be used to determine this return. Assuming that the player wagered 100 credits on the hand, the player will receive a return of 100 credits even if the player declines to perform any additional card replacements. If the expected return associated with replacing the other three cards is 147 credits, then the expected cost to the house for performing the replacement is 147−100=47 credits. Thus, in order to break even, the house should charge the player at least 47 credits to perform the replacement, which is the difference between 100 credits and the expected return associated with replacing the other three cards. The house may add an additional house margin to this cost. For instance, the house may add a margin of 5% to the cost and charge the player 50 credits (rounded up), as shown in
In the case of card selection 212, the player may relinquish his or her pair of sevens to seek a winning hand with a potentially higher return. Assuming again that the player wagered 100 credits on the hand, without replacing any cards in the hand, the player will receive a return of 100 credits. If the expected return associated with replacing the seven of hearts is 123 credits, then the expected cost to the house for performing the replacement is 123−100=23 credits. Thus, in order to break even, the house should charge the player at least 23 credits to perform the replacement, which is the difference between 100 credits and the expected return associated with replacing the other three cards. Again, the house may add an additional house margin to this cost. For example, adding a house margin of 5% to the cost will result in charging the player 25 credits (rounded up), as shown in
The expected return associated with replacing a particular set of cards may be calculated in a number of ways. For instance, the expected return may be based just on the cards in the player's hand. However, the remaining cards in the deck may also be considered, as well as any cards that have already been discarded. The costs associated with any offers provided at each stage of the card game may be calculated dynamically, calculated based on statistical tables, or some combination of both.
One method of calculating an expected return associated with replacing a given set of cards in the player's hand is to calculate, based on the cards being held by the player, the cards discarded by the player, and the cards remaining in the deck, the probability of the player achieving each winning hand in the pay table. Then, each of these probabilities may be multiplied by the return associated with the respective winning hand to determine an expected return. Thus, the cost of a card replacement cycle may be dynamically calculated based on the state of the game and a pay table.
For example, consider card selection 212. The probability of the player receiving a five or a ten to replace the seven of hearts and complete the straight is 7/44. In particular, assuming a 52-card deck, five cards were dealt initially, three of which were replaced in the first card replacement cycle. Thus, there are 44 cards remaining in the card supply. There are a total of eight combined fives and tens in the deck, but one of these was discarded during the first card replacement cycle, leaving a total of seven cards that will complete the straight out of the 44 cards remaining. Of course, replacing the seven of hearts could also result in other types of winning or losing hands. The cost of the second card replacement cycle for card selection 212 may then be calculated as the difference in the player's expected returns between (a) the player's current hand, and (b) the average of all potential outcomes of replacing the seven of hearts.
In some situations, the cost of a card replacement cycle may be negative. In these situations, the house may effectively “pay” the player to replace one or more of the cards in his or her hand. For example, suppose that the player has a straight flush. If the player replaces one or more of his or her cards, the expected return of the resulting hand after this card replacement cycle may be less than the return on a straight flush. Thus, it behooves the house to attempt to convince the player to undertake the card replacement cycle.
In order to do so, the house might offer the card replacement cycle for free, or might offer the player a number of credits to perform the card replacement cycle. For instance, if performing the card replacement cycle lowers the player's expected return by 20 credits, the house might offer the player up to 20 credits to perform the card replacement cycle.
In addition to being played as table games, the embodiments of card games described herein may be facilitated through the interconnection of computers and computer networks. The advantages of computerized gameplay include allowing the player to engage in the card games from the privacy of his or her own home, or via a mobile device from virtually anywhere.
In
Furthermore, the communication network 316 may be purpose-built or hardcoded network designed for the support of networked games. For example, the gaming server 310 may be a mainframe computer and the client devices 312 may be so-called “dumb terminals” that only communicate with the gaming server 310. Thus, the communication network 316 may only comprise communication links between the devices they connect. Alternatively, the gaming server 310 and one or more client devices 312 may be combined into a standalone gaming machine, such as a video game console.
The client devices 312 and the gaming server 310 may include various computing technologies, such as those that are semiconductor-based, magnetic, optical, acoustic, or biological in nature, any combination of these computing technologies, or any other technology known today or developed in the future, that can be used in conjunction with computational devices. A networked game architecture may also be defined to comprise more or fewer elements. For example, the gaming server 310 may be distributed across more than one physical or logical device.
A. Server Devices
The gaming server 310 may comprise a computing device with input, output, processing, storage, and memory functions. The gaming server 310 may be a form of personal computer, or may be physically designed for server operation. For example, the gaming server 310 may be a rack-mounted or blade server component. With respect to the depiction of the gaming server 310 in
The gaming server 310 may run a standalone or distributed operating system to enable server functions. This operating system may be based on Microsoft Windows, Apple's MacOS, Linux, FreeBSD or various other technologies. These operating systems preferably support multiple processes or threads of execution so that a single gaming server 310 can support a potentially large number of networked games simultaneously. Additionally, the gaming server 310 may be provisioned with a network connection.
The gaming server 310 preferably operates under control of a server-stored program (not shown) capable of enabling the client devices 312 to participate in one or more networked games. The stored program in the gaming server 310 may also maintain a dynamic register of all participants admitted to, and actively participating in, a networked game, together with data representative of the corresponding networked game.
Additionally, the gaming server 310 may contain, or have access to, accounts associated with each of these participants. Thus, the gaming server 310 may add credits to or debit credits from these accounts in accordance with the networked game being played. Furthermore, the gaming server 310 may have an interface from which a given participant may access his or her account in order to add more credits, or to cash out the account's credit balance. Moreover, the gaming server 310 may also have an administrative interface, from which an administrator of the gaming server 310 can add, delete, or modify accounts or game settings.
B. Client Devices
The client devices 312 may comprise personal computers, computer terminals, laptop computers, wireless communication devices such as cell phones, personal digital assistants, or similar devices. Furthermore, the client devices 312 may operate under an operating system such as Microsoft Windows, Apple MacOS, Linux or FreeBSD, and are preferably provisioned with a web browser and network connection.
Using the client device 312, card games may be facilitated by a client process (not shown) that executes on the client device 312, and the server-stored program (not shown), or server process, that executes on the gaming server 310. In order to play a card game from any client device 312, a client process may first be downloaded, for example, from the gaming server 310 to the client device 312. The downloaded client process may then be installed in the client device 312, where after it is ready for execution. Alternatively, the client process may execute from within a World Wide Web browser of the client device 312. In either case, once the client process is launched, communication between the client device 312 and the gaming server 310 may then proceed.
The output functions of client devices 312 may comprise a graphical user interface (GUI) rendered on display 314. Such a GUI may represent networked game information in some combination of graphics and text. For example, a GUI on display 314 may represent the state of a card game associated with the client device 312, and include options to perform the acts of playing the card game, and, during the course of the card game, accepting or rejecting offers to redeal, replace, or discard cards. The client process executing on the client device 312 may display different trade marks, color schemes, or “look and feel” depending on the card game being played.
C. Functional Model of Gaming Servers and Client Devices
The processor 402 preferably includes one or more central processing units (CPUs), such as one or more general purpose processors and/or one or more dedicated processors (e.g., application specific integrated circuits (ASICs) or digital signal processors (DSPs), etc.) The data storage 404, in turn, may comprise volatile and/or non-volatile memory and can be integrated in whole or in part with the processor 402. Alternatively, part or all of the data storage 404 may be external to computing device 400, and thus may take the form of remote storage or network storage. The data storage 404 preferably holds program instructions executable by the processor 402, and data that is manipulated by these instructions, to carry out various functions described herein. Alternatively, the functions can be defined by hardware, firmware, and/or any combination of hardware, firmware and software.

For example, the data storage 404 may contain data associated with the state of a card game, data associated with a player's account, and so on. The data storage 404 may also contain program instructions that are executable by the processor 402 to perform any of the gaming server or client device methods, processes, or functions presented herein or represented by any of the accompanying figures.
The network interface 406 may take the form of a wireline connection, such as an Ethernet, Token Ring, SONET, or T-carrier connection. The network interface 406 may alternatively or additionally take the form of a wireless connection, such as IEEE 802.11, BLUETOOTH®, CDMA, WIMAX®, UMTS®, LTE®, or any other interface used to communicate. However, other forms of physical layer connections and other types of standard or proprietary communication protocols may be used over network interface 406. Furthermore, the network interface 406 may comprise multiple physical or logical network interfaces, each capable of operating according to the same or different protocols.
The input/output function 408 facilitates user interaction with the computing device 400. The input/output function 408 may comprise multiple types of input devices, such as a keyboard, a mouse, a touch screen, and so on. Similarly, the input/output function 408 may comprise multiple types of output devices, such as a monitor, printer, or one or more light emitting diodes (LEDs). Additionally or alternatively, computing device 400 may support remote access from another device, via the network interface 406 or via another interface (not shown), such an RS-232 port.
It should be understood that each of the methods illustrated by these figures may include more or fewer steps. Furthermore, the steps of any two or more of these message flow diagrams and flow charts can be combined with one another, in whole or in part, without departing from the scope of the embodiments herein. Moreover, the costs in each of the example embodiments related to
After receiving the first set of replacement cards, the client entity 312 may provide a second request for replacement cards to the gaming server 310. In response to receiving the second request, at step 512 the gaming server 310 may determine a second set of replacement cards. Additionally, at step 514, the gaming server 514 may debit the client entity's account by a first cost. The first cost may be determined at any point prior to step 514, and may be proportional to the expected gain, or a relative advantage, that replacing the chosen cards in the player's hand with the second set will provide the player. Then, at step 516, the gaming server 310 may provide a representation of the second set to the client entity 312.
At step 612, a second request to exchange cards is received from the client entity. In response to receiving this second request, at step 614 a second set of replacement cards may be determined, and a step 616 a third card of hands may be formed by replacing at least one card in the second hand with the second set. Then, at step 618, this second set is provided to the client entity.
The client entity 312 may consider whether to carry out the replacement of the first set based at least on this cost. If the client entity 312 chooses to replace the first set, at step 710 the client entity 312 may make a request to the gaming server 310 to replace the first set. In response to this request, the gaming server 310 may, at step 712, debit the cost from the account of the client entity 312, and, at step 714, determine a second set of replacement cards to replace the first set. Preferably the cards in the second set are chosen randomly from those remaining in the card supply. Then, at step 716, the gaming server 310 may provide a representation of the second set to the client entity 312.
At step 810, a request to replace the first set is received from the client entity. In response to receiving this request, at step 812 the first set of cards may be replaced by a second set of cards. Preferably the cards in the second set are chosen randomly from those remaining in the card supply. At step 814 the cost may be debited from the client entity's account, and at step 816, the second set may be provided to the client entity.
It should be understood that client entity 312 may be physically or logically distinct from the gaming server 310. Thus, client entity 312 may be a client machine that is communicatively linked to the gaming server 310 by a network. In this case, the gaming server providing information (e.g., representations of cards and/or representations of costs) to the client entity 312 may comprise the gaming server 310 transmitting the information through the network.
Alternatively, the client entity 312 may be physically or logically combined with the gaming server 310. Thus, the client entity 312 may be a user interface that is coupled to the gaming server 310, and the gaming server 310 providing information to the client entity 312 may comprise displaying the information on the user interface.
