Definitions

  • 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.
  • 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.
  • house profit is likely to increase when the house provides new variations of known card games.
  • the methods and devices discloses 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.
  • 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.
  • 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.
  • the player may be associated with an account that is either held by the house or by a third party.
  • 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.
  • the player may opt to select one or more cards for a second card replacement cycle.
  • the player may incur a cost for performing this second cycle.
  • 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.
  • Card games that provide players with opportunities to improve their hands are presented.
  • 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.
  • card game preferably refers to a single instance or single play of a game such as poker.
  • 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.
  • 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.
  • non-standard playing cards may be used as well without departing from the scope of the invention.
  • multiple decks of cards may be used as the supply of any cards drawn or dealt.
  • 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.
  • 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.
  • 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.
  • 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 Example winning hands in poker. Wining Hand Return Description Royal Flush 250-to-1 A straight flush consisting of a sequence of cards from ten through ace of the same suit. Straight Flush 50-to-1 Five cards in sequence and of the same suit. Four of a Kind 20-to-1 Four cards of the same rank. Full House 10-to-1 Three cards of a first rank and two cards of a second rank. Flush 6-to-1 Five cards of the same suit. Straight 4-to-1 Five cards of any suit in sequence. Three of a kind 3-to-1 Three cards of the same rank. Two Pair 2-to-1 Two cards of a first rank and two cards of a second rank. One Pair 1-to-1 Two cards of the same rank.
  • 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.
  • 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.
  • FIG. 1 illustrates such a card replacement cycle.
  • the player has been dealt an initial hand 112 consisting of a seven of clubs, a seven of hearts, an eight of spades, a queen of diamonds, and a five of hearts.
  • the player has achieved a winning hand of one pair.
  • the return on one pair may not be significant. Therefore, in order to improve his or her hand, the player may want to replace any one or more of these cards.
  • Figure 1 shows the player choosing to replace the eight of spades, queen of diamonds, and five of hearts, while holding the two sevens. Presumably, the player does this in an attempt to improve to two sevens from a one pair winning hand into a better winning hand, such as two pair, three of a kind, full house, or four of a kind. Once the player has selected the cards to be replaced, these cards may be discarded and replacement cards may be drawn from the deck.
  • Figure 1 also shows the player's hand after replacement 114.
  • the player has drawn a six of clubs, an eight of diamonds, and a nine of clubs. These cards do not improve the player's hand, as the player still has only one pair.
  • the player's hand after this first card replacement cycle would be applied to a pay table, such as Table 1, and the player would be awarded, for example, a 1-to-1 return.
  • 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.
  • 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.
  • Figure 2 continues the scenario illustrated in Figure 1 .
  • the player's hand consists of a seven of clubs, seven of hearts, six of clubs, eight of diamonds, and nine of clubs.
  • the player selects one or more cards of these cards for a second replacement.
  • card selection 210 the player selects the six of clubs, eight of diamonds, and nine of clubs for replacement, thus holding the two sevens.
  • the player is once again attempting to improve his or her one pair into two pair, three of a kind, a full house, or four of a kind.
  • the player selects the seven of hearts for replacement, while holding the remaining cards. In this situation, the player is presumably attempting to achieve a straight by drawing a five or a ten as the replacement for the seven of hearts.
  • 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.
  • 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.
  • the player may be offered one or more additional card replacement cycles.
  • 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.
  • 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.
  • any cards the player discards during a card replacement cycle may be placed in a discard pile.
  • cards in the discard piie are not used for the remainder of the card game.
  • all cards may be gathered, shuffled or otherwise randomized, and used as a card supply for a subsequent card game.
  • each of the card selection 210 and the card selection 212 may be associated with a cost to the player.
  • 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.
  • the player has a pair of sevens, which is a winning hand that returns 1-to-1.
  • 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 Figure 2 .
  • 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.
  • the cost of a card replacement cycle may be dynamically calculated based on the state of the game and a pay table.
  • the probability of the player receiving a five or a ten to replace the seven of hearts and complete the straight is 7/44.
  • five cards were dealt initially, three of which were replaced in the first card replacement cycle.
  • 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.
  • the cost of a card replacement cycle may be negative.
  • 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.
  • 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.
  • 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.
  • Figure 3 depicts an example of such a computerized arrangement.

  • the client entity 312 may then select a first set of one or more cards from the hand to replace, and at step 704 provide a representation of this first set to the gaming server 310.
  • the gaming server 310 may determine a cost to replace the first set, and at step 708 may provide a representation of this cost to the client entity 312.
  • the cost is based on the difference between (a) the return of the hand of cards without any cards being replaced, and (b) the expected return of the hand of cards if the first set is replaced by cards chosen randomly from those remaining in the card supply.
  • 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.
  • FIG 8 is a flow chart of a method 800 also for facilitating replacement of one or more cards in as hand.
  • a hand of cards is determined and provided to a client entity, such as client entity 312.
  • a first set of cards from the hand to replace is received from the client entity.
  • a cost for replacing the first set may be determined.
  • the cost may be based on the difference between (a) the return of the hand of cards without any cards being replaced, and (b) the expected return of the hand of cards if the first set is replaced by cards chosen randomly from those remaining in the card supply.
  • the cost is provided to the client entity.
  • a request to replace the first set is received from the client entity.
  • the first set of cards may be replaced by a second set of cards.
  • the cards in the second set are chosen randomly from those remaining in the card supply.
  • 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.
  • client entity 312 may be physically or logically distinct from the gaming server 310.
  • client entity 312 may be a client machine that is communicatively linked to the gaming server 310 by a network.
  • the gaming server providing information e.g., representations of cards and/or representations of costs
  • the client entity 312 may comprise the gaming server 310 transmitting the information through the network.
  • the client entity 312 may be physically or logically combined with the gaming server 310.
  • 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.
  • the terms "random” or “randomly” shall refer to any realizable process of randomly generating events. Such processes shall include, but not be limited to, generating events without a deterministic pattern of occurrences. Additionally, these processes, may be pseudo-random, thus resulting in a deterministic pattern of occurrences that exhibit some form of statistical randomness.
