Definitions

  • multi-state card games such as but not limited to blackjack and baccarat
  • a player competes against an opponent.
  • the player may be human and the opponent may be a dealer who plays on behalf of a "house" (e.g., a game provider such as a casino).
  • a "house” e.g., a game provider such as a casino.
  • These card games are typically played in hands, where each hand involves an initial number of cards being dealt from a deck to each participant.
  • the cards that each participant holds during a hand may be referred to as the participant's hand, and cards may be added to or taken away from each participant's hand during the course of the hand.
  • the methods and devices disclosed herein provide enhancements to multi-state card games by giving players an opportunity to improve their positions at various stages during a hand of the card game. In doing so, the players may find the overall game more enjoyable and therefore engage in additional gameplay. As a result, the house may benefit from the increased gameplay, more players and/or a higher profit margin.
  • a player and an opponent may be engaged in a multi-state card game, such as blackjack or baccarat.
  • the opponent may be the house (e.g., a dealer) or another player.
  • the player is associated with an account that stores the player's balance of credits.
  • the player and the opponent may each be dealt a hand of cards.
  • the player may be able to view all of his or her cards, and possibly some or all of the opponent's cards as well. From any revealed cards, the player may be able to estimate the relative strength of his or her hand in comparison to the opponent's hand.
  • the player may be offered an opportunity to redeal the player's hand, the opponent's hand, or both.
  • Each of these offers may be associated with a cost.
  • the player may have to pay a first number of credits to redeal his or her hand, a second number of credits to redeal the opponent's hand, and/or a third number of credits to redeal both hands.
  • the cost associated with each option is based on a relative advantage to the player of performing the redeal. If the player accepts one or more of the offers, the player's account may be debited by the cost associated with the offer, and the redeal may take place. Then, with the cards redealt, the card game may continue until a winner is determined.
  • Some multi-state card cards involve gameplay wherein the player and/or the opponent may add or remove cards from their respective hands in order to potentially improve their chances of winning the card game. For instance, in a game of blackjack, the player may "hit" to add cards to his or her hand until he or she is either satisfied and stands, or goes bust.
  • the player may be offered an opportunity to modify his or her hand by discarding the new card, replacing the new card with another new card, redealing the player's hand, redealing the opponent's hand, or some combination of these offers.
  • each of these offers may be associated with a cost, and the associated costs may be based on a relative advantage to the player of accepting the offer.
  • the player's account may be debited by the cost associated with the accepted offer(s), and the modification may take place. Then, with the hand(s) modified, the card game may continue until a winner is determined.
  • Multi-state card games that enable players to redeal their hand, their opponent's hand, or to discard or replace a drawn card are disclosed.
  • a player of these games may be able to, at a cost, improve his or her hand.
  • 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.
  • a player may establish an account.
  • the account may be managed either by the house or a third party.
  • the player may load the account with a number of credits, and may wager these credits on the outcome of these card games.
  • Such credits may be or may represent a denomination of money, a representation of money, or items of value that may 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.
  • a player may load credits into their account via cash payment, credit card, electronic funds transfer, or some other means.
  • a multi-state card game may be one in which the state of a player's hand of cards may change through the course of the hand. For instance, the cards may be added to or removed from the player's hand according to the game's rules. Additionally, some cards in the player's hand may be replaced. Each time the cards in the player's hand or the opponent's hand changes, the state of the card game also changes. However, the state of the card game may change without the cards in any hand changing (e.g., cards may be drawn from a card supply and then discarded without being placed in a hand). Based on the state that the card game is in, the player and/or the opponent may be offered various gameplay options.
  • multi-state 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 from 1 (ace) to 10, and three of which are preferably face cards, such as a jack, a queen, and a king. On the other hand, non-standard playing cards may be used as well without departing from the scope of the invention. Additionally, multiple decks of 52 cards may be used as the supply of any cards drawn or dealt.
  • blackjack and baccarat The following sections describe the play of two popular multi-state card games, blackjack and baccarat.
  • the embodiments herein may be used with other types of multi-state card games, and are not limited to blackjack or baccarat.
  • blackjack, baccarat, and other types of multi-state card games may be played according to alternate rules and variations. For instance, these games may be played according to house rules of the game provider, or local or regional jurisdictional rules. The embodiments here may be applied to these alternate rules as well.
  • Blackjack which also may be referred to as "21,” is a card game in which a player competes against an opponent to assemble a hand of cards that represents a value equal to or less than 21 points.
  • the winner may be awarded the wagers of loser and get their own wager back, or the winner may be paid according to other rules. For example, when the player wins against a house, the player may be awarded returns according to a predetermined house payout schedule (i.e., a pay table), but when the house wins it may be awarded the player's wagers.
  • a predetermined house payout schedule i.e., a pay table
  • Blackjack typically begins with the player and opponent placing any necessary wagers. Then, each is dealt a pair of cards. The player may be able to view both of his or her cards, while the player may only be able to view one card of the opponent's hand. Alternatively, the player may be able to view both or none of the opponent's cards, and the opponent may be able to view none, one, or both of the player's cards.
  • each face card may be worth 10 points, and each non-face card may be worth its labeled number of points.
  • aces may take on a value of either 1 or 11, and this value is typically chosen to be that which is most advantageous to the holder of the ace.
  • a hand consisting of a seven and a queen may be worth 17 points, while a hand consisting of a four and an ace may be worth either 5 or 15 points.
  • the goal of both participants may be to achieve a hand with a total value of less than or equal to 21 points.
  • the participants may "hit" to request one or more additional cards. Each additional requested card may be added to the participant's hand. As long as the total value of the participant's hand has not exceeded 21 points, the participant may continue to hit. Once the total value of the participant's hand exceeds 21 points, the participant "busts" and loses the game. After any hit that results in the participant's hand containing 21 or fewer points, the participant may decide to stop hitting and "stand” with their hand in its present state.
  • a player may employ various strategies when determining whether or not to hit. For instance, if the total value of the player's hand is 11 or less, hitting can only improve the player's hand, so the player is likely to request at least one more card. However, if the total value of the player's hand is 17 or more, it is very likely that hitting will cause the player to bust. Thus, in the latter situation, the player may be less prone to hit.
  • the player may take into account any cards in the opponent's hand that the player can view. For instance, if one of two cards in the opponent's hand is face up, and this face up card is a 10 or a face card, the play may assume that the total value of the opponent's hand is close to 21. Thus, in this situation, the player may hit more aggressively.
  • the opponent may follow a particular set of rules when hitting. For instance, the opponent may be required to hit until the opponent's total value is 17 or higher, even if doing so would be likely to cause the opponent to bust. Accordingly, when playing against a house, the player may take such rules into account when determining whether to hit.
  • each participant's cards may be revealed to the other.
  • each participant's wagers may be returned to that participant, or a winner may be designated by house rules. For instance, house rules may establish that an opponent playing on behalf of the house is declared winner of any tie.
  • Baccarat is a card game in which a player competes against an opponent to assemble a hand of cards that represents the highest value equal to or less than 9 points. Like blackjack, the winner may be awarded the wagers of loser and get their own wager back, or the winner may be paid according to other rules. For example, when the player wins against a house, the player may be awarded return according to a predetermined house payout schedule, but when the house wins it may be awarded the player's wagers.
  • a hand dealt to a human may be referred to as the "player” hand and a hand dealt to a house may be referred to as the "bank” hand.
  • Each participant in a game of baccarat may wager on either the "player” or the "bank” winning the hand.
  • the term "player” used throughout this specification typically refers to a hand controlled by a human player, in baccarat, a player may actually be wagering on the "bank” hand.
  • each face card may be worth 10 points, and each non-face card may be worth its labeled number of points.
  • the total point value of a hand may be the sum of the point values of all cards in the hand, modulo 10.
  • a hand consisting of a five and a two may be worth 7 points
  • a hand consisting of a seven and a queen may also be worth 7 points
  • a hand consisting of three nines may also be worth 7 points.
  • Punto Banco also known as North American Baccarat
  • Punto Banco is typically a game of chance, with no skill or strategy involved.
  • a player's “decisions” may be dictated purely by the cards that the player is dealt.
  • Chemin de Fer the player has choices that allow the player to apply skill and strategy to the game.
  • Punto Banco variation two cards are dealt to the player and two cards are dealt to the opponent. If this deal results in either the player's hand or the opponent's hand having a total value of 8 or 9 points, both participants must stand, no further cards are dealt. If the player hand has a total value of 5 points or less, a third card is dealt to the player's hand, and then the player must stand.
  • Whether the opponent draws a third card may be based on the point value of the player's third card, as well as the total point value of the opponent's two cards. For example, the opponent may draw a third card or stand based on the rules provided in Table 1. In Table 1, an entry of D indicates that the opponent may draw, while an entry of S indicates that the opponent may stand. Thus, if the opponent's total point value is 4 and the player's third card was a 2, the opponent may draw a third card. However, if the opponent's total point value is 6 and the player's third card was a 5, the opponent may stand.
  • the opponent's third card rules encoded in Table 1 are for purposes of example, and this and other variations of baccarat may be played using other rules for determining whether an opponent draws a third card.
  • Table 1 Baccarat opponent third card rules. Player's Third Card Opponent's Two Card Total 0-2 3 4 5 6 7 N/A D D D D S S 1 D D S S S S S 2 D D D S S S 3 D D D S S S 4 D D D D D S S 5 D D D D S S 6 D D D D D D S 7 D D D D D D D S 8 D S S S S S 9 D D S S S S S 10 D D D S S S S S S S
  • the total point value of the two hands are compared, and the hand with the higher value wins.
  • a tie several options are possible, including either the player or the opponent being designated as winner by default, or no return to either the player or the opponent.
  • Punto Banco Similar to the Punto Banco variation, once both the player and the opponent stand, the total point value of the two hands may be compared, and the hand with the higher total point value may win. Also like Punto Banco, in the case of a tie, several options are possible. These options include either the player or the opponent being designated as winner by default, or no return to either the player or the opponent.
  • Each of the card games described in the previous section, as well as other types of multi-state card games, may be enhanced by optional rules allowing a player to redeal the player's hand, redeal the opponent's hand, replace a drawn card, discard a drawn card, or some combination of these options.
  • Each of these options may be associated with a cost, and the cost may be based on the relative advantage that executing the option provides to the player. By offering these options, the player's interest in the card game may remain high even if the player is dealt a weak hand.
  • Figure 1 illustrates a first embodiment of the invention, as applied to the initial deal of a hand of blackjack.
  • the opponent has been dealt a hand 110 consisting of a queen and a ten, for a total of 20 points.
  • the player has been dealt a hand 112 consisting of an eight and a seven, for a total of 15 points.
  • this hand would likely be a weak hand for the player. If the player stands, he or she will lose. However, if the player hits, it is likely that he or she will bust, and thus still lose.
  • the player may be offered one or more ways of improving his or her odds of winning the hand.
  • Figure 1 illustrates the player being offered the options to redeal the opponent's hand 114 and/or redeal the player's hand 116. These options are associated with costs of 10 credits and 15 credits, respectively. The player may choose one or both of these options. If the player chooses both options, then the associated cost may be the sum of the cost for each option (i.e., 25 credits) or some other amount. The player may also choose the continue option 118 to continue playing the hand without a redeal.
  • the cards in the chosen hand may be discarded and replaced by new cards, and play may continue.
  • the player's account may be debited the cost of the selected option.
  • the new cards are drawn from the same deck as was used to deal the initial two hands.
  • the player may be once again presented with the options shown in Figure 1 .
  • the player may continue to redeal either or both of the hands 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 redeals per hand.
  • the representation in Figure 1 of the opponent's hand 110, the player's hand 112, and the redeal options 114 and 116, as well as the continue option 118 may be incorporated into the play of a table game, or may be presented to the player on a computer screen. In the latter case, redeal options 114 and 116 each may be presented as a virtual button on a computer display. Through an input device such as a mouse or a touchscreen, a player may depress none, one or both buttons before depressing continue 118.
  • Figure 1 has been described to represent a hand of blackjack, Figure 1 could alternatively represent a hand of baccarat.
  • the player may be offered option 114 to replace the opponent's hand, option 116 to replace the player's hand, or both.

  • Figure 2 has been described to represent a hand of blackjack. However, Figure 2 could alternatively represent a hand of baccarat. Thus, after the player draws a third card but before the opponent has an opportunity to draw a third card, the player may be offered the options shown in Figure 2 .
  • the multi-state card games discussed herein may include variations in which zero or more of the opponent's cards are face up or face down. Furthermore, when a player accepts an offer to redeal the opponent's hand, these variations may either redeal just the opponent's face up cards, just the opponent's face down cards, or all of the opponent's cards.
  • each of the options illustrated in Figures 1 and 2 may be associated with a cost to the player.
  • the cost of an offer is proportional to the expected gain that acceptance of the offer will provide the player.
  • the cost associated with an offer to exchange the cards in that hand may be relatively high.
  • the cost associated with an offer to exchange the cards in this better hand may be relatively low.
  • the cost associated with an offer to exchange the cards in such a strong hand may be negative or zero. In this way, the house can encourage a player to accept an offer that is likely to lower the strength of the player's hand:
  • the following blackjack scenario provides an example of how the cost of an offer may be calculated. Assume that a blackjack game is played with a single deck of cards and that the participants wager 100 credits per hand. Assume further that the player's cards are an ace and a 9 and the opponent's hand is showing an ace and also contains a face down card. Without a redeal option, the optimal move for the player may be to stand. Assume, for purposes of this example, standing would result in an expected return of 113 credits for the player, for a profit of 13% on the 100-credit wager.
  • the house may determine the cost associated with the offer to be at least 48 credits. For example, the house may include a 5% margin (rounded up) of 3 credits on the offer, thus making the cost associated with the offer 51 credits.
  • the player decides to redeal the player's hand instead of redealing the opponent's hand.
  • the true cost of the redeal to the house is -52 credits, the difference between 61 and 113 credits.
  • the house expects to gain 52 credits if the player accepts the offer.
  • the house may associate a cost of zero with the offer, or associate a negative cost with the offer, thus "paying" the player to accept the offer. Any such negative cost should pay the player no more than 52 credits.
  • the house may again include a 5% margin (also rounded up) of 3 credits on the offer, thus paying the player 49 credits to accept the offer.
  • expected returns may be calculated in a number of ways. For instance, the expected returns may be based just on the cards in the hands of the player and the opponent. 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 games may be calculated dynamically, calculated based on statistical tables, or calculated based on some combination of both.
  • the opponent will receive a new card.
  • the probability of the opponent receiving a new card of a given rank depends on the cards that have already been dealt prior to the point of the offer to redeal.
  • the opponent has a probability of 2/48 of being redealt an ace, as only two aces remain in the deck and four cards have been dealt from the deck of 52 cards.
  • the cost of the redeal may then be calculated as the difference in the player's expected returns between (a) the current player and opponent hands, and (b) the average of all potential outcomes with the opponent's hand redealt.
  • 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.
