BACKGROUND OF THE INVENTION The present invention relates to a poker game with one or more cards having a negative impact on a hand in the game.
Gaming device manufacturers strive to make gaming devices that provide as much enjoyment and excitement as possible. Wagering machines such as slot machines are games of luck demanding minimal skill from the player. Card games such as blackjack and poker, however, include luck and a reasonable amount of strategy or knowledge of the game. For instance, the player is lucky to receive four aces in poker. The player should also know that it is unwise to forego three-of-a-kind to play for a straight in poker or split two tens in blackjack.
Video poker machines used for gaming are well known in the art. Most conventional video poker gaming machines used in casinos implement conventional rules for poker by dealing five initial cards face up from a standard deck of fifty-two cards and allowing the player to hold any number of the dealt cards. The player can press a draw button which causes the non-held or discarded cards to be replaced with new cards from the deck. The player is provided an award for a winning hand, if any, according to a payout table. In a conventional poker game, each and every card in a fifty-two-card deck can be a part of a winning hand if it is the highest-valued hand obtained. Even a card such as a two, which, alone, is of low value, can be valuable if it is drawn with other cards such as a three, four, five and six of the same suit�a straight flush. No card in the deck has a negative impact on the game.
A continuing need exists for different, interactive and enjoyable games which can add additional challenges to the player without increasing the level of difficulty beyond the ability of the average player to experience a sufficient level of success and enjoyment. A continuing need also exists to provide new, challenging and entertaining card games which are relatively easy to learn and play.
SUMMARY OF THE INVENTION The present invention provides a standard deck of cards including one or more negative impact cards. The present invention can be employed as a gaming device or as a table game. In addition, the present invention can be employed as a primary wagering game or a secondary game such as a bonus game. Furthermore, the present invention can be employed in any suitable card game such as poker.
The present invention is described primarily with respect to a poker primary wagering game; however, it should be appreciated that the present invention can be employed as a secondary game and with other suitable card games. This game includes an actual or virtual deck of cards such as a conventional deck of fifty-two cards. Each card of the deck has multiple characteristics including a value and suit combination which is visible when the card is turned face up. The suits include thirteen cards of different values from each of the suits of spades, clubs, diamonds and hearts. The deck also includes at least one, or, alternatively, a plurality of negative impact cards.
In one embodiment, two cards such as jokers are included in the deck in addition to the typical fifty-two cards. The first joker or type of card has a positive impact on the game by acting as a wild card or any of the fifty-two cards for purposes of determining a winning combination or a combination of highest value in a hand. Additionally, the positive impact card, in one embodiment, includes a modifier which favorably modifies the ante pot if the player holds the winning hand. The second joker or type of card has a negative impact on the game by having no value and no use to form any winning combinations. Thus, if obtained by a player, it lessens the chances of the player having a winning combination in the hand.
In one embodiment of the poker game, once dealt to the player (initially or in a draw), the card is not able to be discarded. The negative impact card which cannot be discarded, therefore, prevents the player from obtaining any winning combination requiring more than four cards. It should be appreciated that the player can still obtain other winning combinations such as Four-of-a-Kind, Three-of-a-Kind, etc.
In another embodiment, such as upon a draw in a draw poker game, the player can discard the negative impact card. In such an embodiment, the negative impact card just lowers the chances of a player receiving a winning hand by decreasing the number of potentially winning cards the player is able to play.
Alternatively, the player is permitted to discard any card including the negative impact card under certain conditions such as the initial wager, an additional wager, a limited number of discards in the game or random selection of a card by the game.
In one embodiment, the player can discard the impact card, but will not know if the impact card is a positive or negative impact card when it is dealt. In one embodiment, both types of impact cards will appear the same when dealt. Whether the impact card is a positive or negative impact card is not revealed to the player until after the draw or until the player has chosen to keep or discard the impact card. It should be appreciated that the player may be dealt both types of cards in a single hand in the game.
In one embodiment of the present invention, the player makes a wager and is dealt a hand face up including five initial cards from a conventional virtual deck of fifty-two playing cards plus the two additional cards. The present invention first provides the player with an opportunity for a first draw as in a conventional poker game. The player chooses which initial cards to hold and is dealt replacement cards for the cards not held or discarded by the player. The player is then provided an award based on any winning combination of cards in the hand. Any of the discarding rules above may be employed in this draw poker game. It should also be appreciated that the present invention can be employed in multi-hand games as is understood by those of skill in the art.
It is therefore an advantage of the present invention to provide an entertaining and exciting card game.
It is still a further advantage of the present invention to provide an entertaining and exciting casino table game.
It is yet another advantage of the present invention to provide a new type of playing card with a new function to add additional challenge and excitement to a card game.

Gaming device 10 can incorporate any suitable wagering primary or base game. The gaming machine or device of the present invention may include some or all of the features of conventional gaming machines or devices. If the card game of the present invention is a bonus game, the primary or base game may comprise any suitable reel-type game, card game, number game or other game of chance susceptible to representation in an electronic or electromechanical form which produces a random outcome based on probability data upon activation from a wager. That is, different primary wagering games, such as video poker games, video blackjack games, video Keno, video bingo or any other suitable primary or base game may be implemented into the present invention.
In one embodiment, as illustrated in FIGS. 1A and 1B, a base or primary game may be a poker game wherein the gaming device enables the player to play a conventional game of video poker and initially deals five cards all face up from a virtual deck of fifty-two card deck. Cards may be dealt as in a traditional game of cards or in the case of the gaming device, may also include that the cards are randomly selected from a predetermined number of cards. If the player wishes to draw, the player selects the cards 34 to hold via one or more input device, such as pressing related hold buttons 26 or via the touch screen 42. The player then presses the deal button 20 and the unwanted or discarded cards 34 are removed from the display 30 and replacement cards 34 are dealt from the remaining cards in the deck. This results in a final five-card hand. The final five-card hand 34 is compared to a payout table which utilizes conventional poker hand rankings to determine the winning hands. The player is provided with an award based on a winning hand and the credits the player wagered.
In another embodiment, the base or primary game may be a multi-hand version of video poker. In this embodiment, the player is dealt at least two hands of cards 34. In one such embodiment, the cards are the same cards. In one embodiment each hand of cards is associated with its own deck of cards. The player chooses the cards to hold in a primary hand. The held cards 34 in the primary hand are also held in the other hands of cards 34. The remaining non-held cards 34 are removed from each hand displayed and for each hand replacement cards are randomly dealt into that hand. Since the replacement cards are randomly dealt independently for each hand, the replacement cards for each hand will usually be different. The poker hand rankings are then determined hand by hand and awards are provided to the player.
In one embodiment, as illustrated in FIG. 2B, one or more of the gaming devices 10 of the present invention may be connected to each other through a data network or a remote communication link 54 with some or all of the functions of each gaming device provided at a central location such as a central server or central controller 52. More specifically, the processor of each gaming device may be designed to facilitate transmission of signals between the individual gaming device and the central server or controller.
In another embodiment of the present invention, multiple sets or decks of cards are used for central determination gaming. In central determination, individual game terminals receive randomly generated outcomes from central or server processors. For example, in slot each symbol has a probability of being displayed on the reels after the reels have been spun. The odds of any particular symbol combination being displayed when the reels stop spinning is therefore a combination of the component symbols. In known gaming, the player's outcome is determined randomly by the combination of symbols generated.
With central determination the outcome is generated randomly at the host computer and a set of symbols yielding the outcome is displayed at the gaming terminal. Central determination provides the player with a combination of symbols that appears to generate the generated outcome. For games of pure luck, such symbol generation is facilitated readily because the player has no control. With games like poker, however, which require a degree of strategy and decision making, providing the symbols necessary to generate a previously, randomly determined outcome can become tricky.
In one draw poker embodiment, all winning cards of a predetermined and centrally determined hand are dealt face-up and initially. That prevents the player from keeping losing cards, precluding the player from obtaining the winning cards from a draw. If the player discards any of the initially dealt face-up cards, the gaming device or initial processor provides another winning card in the draw to yield ultimately the predetermined win. For example, if a royal flush is randomly predetermined for and dealt initially to player, and the player foolishly discards the king for a draw card, the king of the same suit is provided to the player from the draw and from the second deck of cards. In that way, the player wins the randomly predetermined result, e.g., the royal flush regardless of the discarded winning card.
The Negative Impact Card In one embodiment of the present invention, at least one negative impact card is included in the cards of a poker game, wherein the negative impact card takes the place of a card that could contribute to a winning combination by not being part of any winning combination of cards. Such a card decreases the probability of obtaining a winning combination and changes the strategy from a five-card to a four-card game when the card is drawn or dealt and cannot be discarded. In a two-pair or better five-card draw poker game with a standard fifty-two card deck and two wild card jokers, the chances of obtaining a winning hand are 0.36 or 1 in every 2.8 hands. However, if a non-discardable negative impact card replaces one of the wild card jokers such that, when dealt, the player has only four cards to generate a winning hand, the probability of obtaining a winning hand is reduced to 0.28 or 1 in every 3.6 hands. Likewise, a discardable negative impact card which is not revealed until after the draw also has a probability of obtaining a winning hand of 0.28 or 1 in every 3.6 hands.
Referring now to FIG. 3, an example of a paytable of one embodiment presents different known combinations of cards associated with a distribution of different award amounts. In addition, the table illustrates the number of cards needed for each winning combination. For example, a Royal Flush, Straight Flush, Full House, Flush, and Straight require five cards for the player to achieve each combination. When a negative impact card is dealt or drawn, and only four cards are considered in determining a winning combination, only the combinations of Four-of-a-Kind, Three-of-a-Kind, Two Pairs, and a Pair of Aces require less than five cards and are available to the player.
Referring now to FIGS. 4A and 4B, in one embodiment of the present invention, the negative impact card is used in a draw poker game in the form of a Joker card, hereinafter referred to as a Negative Joker. In one embodiment, all cards, including the negative impact card(s), are able to be discarded for the draw. In FIG. 4A, an Ace of Diamonds 34 a, a King of Diamonds 34 b, a Ten of Diamonds 34 c, a Five of Spades 34 d and a Negative Joker 34 e are dealt to the player. This combination of cards is not a winning hand, even with the four cards other than the Negative Joker 34 e. The hand, however, has three cards to a winning combination which, in this embodiment, is a Royal Flush. In the embodiment which allows the player to replace undesirable cards including the Negative Joker, the player holds the Ace of Diamonds 34 a, the King of Diamonds 34 b, the Ten of Diamonds 34 c and requests a draw. The gaming device 10 subsequently discards the Negative Joker 34 e along with the Five of Spades 34 d, and deals two additional cards including a Jack of Diamonds 34 f and a Queen of Diamonds 34 g as illustrated in FIG. 4B. The player now holds the winning combination, a Royal Flush, and the player wins an award of 1000 credits according to the paytable of FIG. 3.
In one alternative embodiment of a draw poker game, the player may not discard or exchange the negative impact card even in the first draw. Referring now to FIGS. 5A and 5B, an embodiment of the present invention is illustrated where, in a conventional five-card video poker game, the player has been dealt an initial hand including an Ace of Diamonds 34 a, a King of Diamonds 34 b, a Ten of Diamonds 34 c, a Five of Spades 34 d and a negative Joker or negative impact card 34 g. This is not a winning hand, but the hand has three cards to a winning combination which, in this example, is a Royal Flush. However, the player cannot discard the negative impact card 34 g. The player holds the Ace of Diamonds 34 a, the King of Diamonds 34 b, the Ten of Diamonds 34 c and requests a draw. The gaming device discards the Five of Spades 34 d but does not discard the negative impact card or negative joker 34 g. The gaming device selects and deals one additional card which is a Jack of Diamonds 34 f as illustrated in FIG. 5B. The player now holds four cards to a Royal Flush and the Negative Joker 34 g. The final evaluation is made by the game, and the player does not win because the player does not have a winning hand based on the four remaining cards.
It should be appreciated that in this embodiment a player must shift from a five card game strategy to a four-card game strategy when dealt a negative impact card in the first draw. In other words, when determining whether to hold or discard certain cards, instead of building a winning hand requiring five cards, such as a Straight, Flush, Full House, Straight Flush or Royal Flush, the player must play for a winning combination requiring only four cards such as a Four-of-a-Kind, Three-of-a-Kind, etc. The player in FIG. 6A, for example, has received a hand of a Ten of Hearts 34 a, a Jack of Hearts 34 b, a Queen of Hearts 34 c, a Ten of Diamonds 34 d, and a Negative Joker 34 e. This combination of cards is three cards to the five-card winning combination which, in this example, is a Royal Flush. However, in the embodiment where the negative impact card cannot be discarded, the player must give up the chance at the greater award associated with the five-card winning combination and play for the four-card win of Four-of-a-Kind. The player subsequently holds the Ten of Hearts 34 a and the Ten of Diamonds 34 d, and discards the Jack of Hearts 34 b, and Queen of Hearts 34 c with the hope of drawing a Ten of Spades and a Ten of Clubs to obtain the Four-of-a-Kind. As illustrated in FIG. 6B, the game cooperates with the player's desire and provides the cards needed for Four-of-a Kind-a winning combination demonstrating that a player, in one embodiment, still has the opportunity to win an award when dealt a negative impact card which cannot be discarded. It should be appreciated that a negative impact card, in one embodiment, decreases the probability of obtaining a winning hand in the game but does not eliminate the possibility of obtaining a high award associated with combinations such as a Four-of-a-Kind.
Referring now to FIGS. 7A, 7B, 8A and 8B, in one embodiment of the present invention, the deck of cards includes at least one positive impact card and at least one negative impact card or jokers which can be discarded but will not be indicated as a positive or negative impact card when either is dealt to the player. Both the positive impact card and the negative impact card will appear the same to the player when dealt. In one embodiment, whether the impact card is a positive or negative impact card is not revealed to the player until after the draw or until the player has chosen to keep or discard the card. The two divergent effects a positive and a negative impact card will have on the player's hand must be considered by the player when determining which of the cards, if any, is discarded or held, including the positive or negative impact card. In the embodiment illustrated in FIGS. 7A and 8A, the initial hand dealt to the player includes a Four of Hearts 34 a, a Four of Clubs 34 b, a Four of Spades 34 c, a Seven of Diamonds 34 d, and a Joker 34 e. This combination of cards, in one embodiment, is a Three-of-a-Kind win. In addition, this combination of cards is four cards to the more desirable five-card winning combination which, in this example, is a Full House or three cards to the four-card winning combination which, in this example, is Four-of-a-Kind. In this embodiment, the Joker can be a positive impact card which, if held, would automatically result in a win as a Full House and Four-of-a-Kind due to its wild card status. Alternatively, the Joker can be a negative impact card which, if held, would only result in the Three-of-a-Kind win if all of the other cards are held. The player must, therefore decide whether to play the hand as if the Joker 34 e is a positive impact card or a negative impact card.
In FIG. 7A, the player plays the hand as if the Joker 34 e is a positive impact card and plays for a Full House and Four-of-a-Kind. The player subsequently holds all the cards including the Joker 34 e. In FIG. 7B, the status of the Joker is revealed to the player to be a negative impact card and the player has no win other than Three-of-a-Kind in the initial hand. Because the player held the Seven of Diamonds 34 d to play for the Full House and Four-of-a-Kind, the player gave up the chance of playing for Four-of-a-Kind (by drawing a Four of Diamonds) if the Joker was a negative impact card.
In the embodiment illustrated in FIG. 8A, the player plays the hand as if the Joker 34 e is a negative impact card and plays for Four-of-a-Kind. The player subsequently discards the Seven of Diamonds 34 d and the Joker 34 e to have two chances to be dealt the fourth card of Four-of-a-Kind, the Four of Diamonds. In FIG. 8B, the player receives a winning hand on the draw of Four-of-a-Kind. It should be appreciated that if the discarded Joker 34 e had been a positive impact card, the player would have completed Four-of-a-Kind and would have lost any award associated with drawing a Full House by discarding the Seven of Diamonds 34 d. In an embodiment where the player is provided an award for each winning combination of cards, the player would have lost the opportunity of winning multiple awards associated with the multiple winning combinations of the cards of the initial hand which included a positive impact card.
It should be appreciated that the player may be dealt both positive impact and negative impact cards in a single hand in the game. In the embodiment illustrated in FIGS. 9A and 9B, the initial hand dealt to the player includes a Ten of Hearts 34 a, a Ten of Clubs 34 b, a Ten of Spades 34 c, and two Jokers 34 d and 34 e. This combination of cards, in one embodiment, is a Three-of-a-Kind win. In addition, this combination of cards is three cards to the more desirable four-card winning combination which, in this example, is Four-of-a-Kind. In FIG. 9B, in an embodiment where there are only two Jokers, one a positive impact card and the other, a negative impact card, the player holds all of the cards to preserve the chance of winning a Four-of-a-Kind with one of the Jokers 34 d or 34 e. As illustrated in FIG. 9B, the player holds a winning hand when it is revealed that one of the Jokers is a positive impact card completing Four-of-a-Kind.
In different embodiments in the draw poker game of the present invention, the player is allowed to discard the negative impact card based on the initial bet in the game or the placement of an additional bet. In another embodiment, the player may discard a negative impact card if the player has not exceeded a maximum or threshold number of discards in the game. Additionally, the gaming device may randomly select the negative impact card to be discarded.
In one embodiment, the ability to discard a negative impact card can depend on the amount the player bet in the game. In one embodiment, the poker game enables the player to discard a negative impact card at least once if the player bet the maximum amount. It should be appreciated that basing the ability to discard a card on the amount of the player's bet may be applied only to the negative impact card or, alternatively, to the other cards in the game or, alternatively, to all the cards in the game. Hence, if the player bets the amount required to discard the negative impact card, the player may discard the negative impact card as illustrated in FIGS. 4A and 4B. Likewise, if the player does not bet max or the amount necessary to be able to discard the negative impact card, the player retains the negative impact card and plays the best four of the five dealt or drawn cards as illustrated in FIGS. 6A and 6B.
In an alternative embodiment, the ability to discard the negative impact card depends on an additional bet required by the game to exchange the negative impact card. In one embodiment, the player is allowed to discard the negative impact card only if an additional wager is made or if an additional wager exceeds a predetermined threshold amount required by the game.
An example of a wager schedule of one embodiment of the present invention is illustrated in the table of FIG. 7. The wager schedule provides the amount of the additional wager necessary, in one embodiment, for a player to discard the negative impact card and other cards not desired by the player. The wager schedule of FIG. 7 in comparison with the paytable of FIG. 3, illustrates that if the player replaces all five cards of the initial hand or five cards over a plurality of rounds, the player needs to achieve at least Four-of-a-Kind to win more than the player has wagered (40 versus 32 credits). If the player replaces a negative impact card, four cards of the initial hand or four cards over a plurality of rounds, the player needs to achieve at least a Flush in order to win more than the player has wagered (20 versus 16 credits). If the player replaces three cards of the initial hand or three cards over a plurality of rounds, the player needs to obtain at least a Straight in order to win more credits than the player has wagered (10 versus 8 credits). If the player replaces two cards of the initial hand or two cards over a plurality of rounds, the player needs to achieve Three-of-a-Kind in order to win more than the player has wagered (5 versus 4 credits). If the player replaces only one card of the initial hand or one card over a plurality of rounds, the player needs to achieve at least Two Pairs in order to win more than the player has wagered (3 versus 2 credits). If the player decides not to replace any cards, the player needs to achieve at least a Pair of Aces in order to win more than the player has wagered. It should be appreciated that those skilled in the art could modify the wager schedule of FIG. 8 without departing from the scope of the present invention.
In one embodiment, only discarding the negative impact card requires an additional wager amount. In one embodiment, the amount of the additional wager required to discard a negative impact card is greater than the amount required to discard other cards of the deck of cards. It should be appreciated that the amount of the additional wager to discard the negative impact card may vary from the amount of discarding other cards in any suitable manner and can be more, less or the same as the amount of the wager necessary to replace other cards as desired by the game implementer. As illustrated in the wager schedule of FIG. 8, the game allows the player to discard the negative impact card if the player is willing to wager an additional sixteen credits. The player is faced with a dilemma in a situation as in FIG. 5B where the player is four cards to a Royal Flush. A sixteen-credit wager for the chance to potentially win an award of 1000 credits associated with the Royal Flush in this embodiment may be a tempting choice for the player.
In an alternative embodiment, the additional wager required to discard and exchange the negative impact card may be based on how close the player is to obtaining a winning combination or winning a particular award. In FIG. 4A, for example, the player is four cards to a Royal Flush, a card combination associated with the highest award amount. In one embodiment, the additional wager required to discard the negative impact card in such a situation is greater than the wager required if the player was holding three cards to a Royal Flush as in FIG. 6A, for example.
In one embodiment, the game or dealer removes any discarded cards from the game. In an alternative embodiment, the game or the dealer returns the discarded cards into the deck where they can be re-drawn by the player. In a draw poker game, for example, if the player is required to discard the negative impact card back into the deck, it should be appreciated that the player could receive the negative impact card again on the next draw.
In an alternative embodiment, the negative card is used in a game having multiple rounds of discarding and betting where the player is able to continue to replace other undesirable cards after the first draw. In such a game, the player may be holding and not discarding certain cards in anticipation of building a winning hand. If the player draws a negative impact card which cannot be discarded, the player must switch from a five-card game strategy to a four-card game strategy as illustrated in FIGS. 5A, 5B, 6A and 6B.
In one embodiment of a game with multiple rounds, the player is permitted to discard the negative impact card under certain conditions, i.e. limited number of cards, an additional wager, etc. In one embodiment, the player is permitted to discard a limited number of cards in all the rounds. In another embodiment, the player is permitted to discard a decreasing number of cards in each round such as two cards in the first round, one card in the next round, and no cards in any round thereafter.
In an alternative embodiment of the present invention, the negative impact card is included in a traditional five-card stud poker game. In a traditional five-card stud poker game, the player is not allowed to discard any undesirable card. Therefore, the player in a five-card stud poker game who receives a negative impact card will be playing to achieve the best possible combination of four cards rather than five cards. It should thus be appreciated that in a conventional poker game, the best combination a player who has been dealt a negative impact card can achieve is Four-of-a-Kind.
In a table poker game, in one embodiment of a stud poker game, some of the cards are dealt face-up so that the competing players know if one or more of the players receive a negative impact card. This knowledge assists the players in determining their bets when each card is dealt. The negative impact card will decrease the number of possible combinations available to the player and decrease the probability of obtaining a winning hand. In FIG. 8, for example, in one embodiment of a five-card stud table poker game, the dealer deals a Two of Clubs 82 a and a Two of Hearts 82 b to the player face down. However, the next two cards, a Two of Spades 82 c and a Negative Joker 82 d, in one embodiment, are dealt face up, thereby revealing the negative impact card to the other players. In such a situation, the other players can assume that the best hand that the player who was dealt the negative impact card can hold is a Four-of-a-Kind, a hand which can be beaten by a Straight Flush or Royal Flush. In contrast, when cards other than the negative impact card are revealed to the other players as they are dealt, the value of the cards to the player receiving them is more difficult to assess. Each card may be crucial to a winning hand regardless of its value; however, knowing that a player has a negative impact card and cannot discard the card in a stud poker game allows the other players to adjust their betting accordingly.
In the various embodiments, the game can include more than one negative impact card with the fifty-two card deck(s). The player receiving the negative impact card face up in a stud poker game, for instance, may not be the only player holding a negative impact card. It should be appreciated that the other players may have been dealt a negative impact card face down which is not revealed to the other players. It should also be appreciated that, in such a situation, a player who has not been dealt a negative impact card who is otherwise holding a competitive hand will be more confident in raising the ante on the other players assuming a high likelihood that at least one of the other players is holding a negative impact card.
It should be appreciated that the present invention could be employed in both single-hand and multi-hand versions of video poker games. The strategy of other types of poker games such as seven-card stud where multiple cards are dealt face-up and multiple rounds of betting occur based on those cards, will be dramatically affected by the presence of one or more negative impact cards.
Various embodiments of the present invention may also utilize a different number of cards than in conventional poker games.
It should be appreciated that the present invention can be played without the use of a gaming device, such as in a conventional table poker game.
It should be appreciated that the present invention could be used in card games other than poker.
