The present invention is directed to gaming devices and methods of playing card games wherein cards played from previous hands are discarded and displayed for ready viewing by players.
It is well recognized in the gaming industry that persons playing card games at a casino will have a distinct advantage if, while playing a card game, they know which cards have already been played from the collection of cards being dealt. For example, when playing the game of Blackjack, players have an opportunity to draw additional cards. Those cards are commonly drawn from a card shoe containing a plurality of 52 card decks. Since a number of hands are typically dealt from such a card shoe, during the play of multiple hands, it is difficult and sometimes impossible for players to view all of the cards which have been played by all players and the dealer. Moreover, it is difficult for players to remember all of the cards which have been played. In fact, it is common practice for casinos to ban the practice of card counting. Players suspected of card counting are typically ostracized from casinos, since knowledge of the cards previously played offers players a significant advantage. The advantage arises from the player's ability to predict which cards are remaining in the card shoe. For example, if many high value cards have previously been played, then the player will realize the likelihood of drawing a low value card is high, and vice versa. Since casinos have traditionally desired to avoid increasing the players chances of winning, casinos have disfavored devices or methods of play which tend to increase the players chances of recalling which cards have already been dealt from a card shoe. Those skilled in the art will appreciate that this same prevalent thinking has also applied to other games where players have had the opportunity to draw cards from a predetermined collection of cards, for example a single deck or multiple decks of cards.
It is also common practice in the gaming industry to have all cards played during a card deal on an electronic gaming device, e.g. a video poker machine, to be effectively “reshuffled” after each card deal. The practice of reshuffling between card deals prevents players from counting cards and gaining an advantage in subsequent deals.
Players often desire to play new games of chance, particularly games which are perceived to offer greater likelihoods of achieving a winning outcome or games which offer opportunities for higher payouts.
Embodiments of the present invention are directed to gaming devices and methods of playing card games wherein an indication of which cards have already been discarded is displayed for the player or players to view. The various aspects of the present invention are contrary to traditional casino practices which tended to impede a player's ability to see and/or recall the cards previously played.
One preferred aspect of the present invention is directed to a gaming device comprising a video display which is designed for the play of Blackjack. Cards are dealt to one or more hands from a simulated multi-deck card shoe. For example, a single player may be provided with the opportunity to play five hands of Blackjack during a single card hand. After the hand is played or after the cards are dealt, an indication of the cards used is shown in a discarded card table. Therefore, when a player is deciding whether to draw another card, the player can readily see which cards have already been played. If the player needs an ace and all of the aces have already been discarded, then the player will know that it would be futile to try to draw an ace. In a similar manner, the player can assess the likelihood of drawing relatively high or low cards from the number of such cards already discarded.
Another preferred embodiment of the present invention comprises providing a player with an opportunity to play a game wherein cards are drawn from a multi-deck card shoe, for example, a six deck shoe and wherein a “cut card” is randomly placed in the deck. The player or players are then dealt cards from those cards forward of the “cut card”. When a cut card or similar step is taken to establish a subset of cards from which cards will be dealt, players cannot actually determine the likelihood of drawing a specific card but can still get an idea of the likelihood of drawing one or more specific value cards. Specific card values or cards falling within predetermined ranges which have been discarded and dealt in previous hands are available for display to a player. The player may be required to meet certain criteria, such as wagering a predetermined amount or making an additional payment, in order to receive access to some or all of the information regarding previously played cards.
Another aspect of the present invention is directed to a keno game wherein a plurality of keno-type games are played by drawing indicia, e.g. numbers, from a single pool of numbers. According to this embodiment of the present invention, players are provided with an opportunity to wager on one or more keno games subsequent to the first keno game while having the ability to view which numbers had been played on the initial or other previous games.
Another aspect of the present invention comprises methods and electronic gaming devices, e.g. video card game machines wherein cards are not reshuffled after every deal. According to these embodiments of the present invention, a player will receive multiple deals, each of which can comprise one or more hands, out of a single collection of cards.
Other aspects of the present invention are directed to table versions of the present invention wherein physical playing cards are actually dealt to one or more players. At the conclusion of hand, an indication of the discarded cards is displayed for viewing by all of the players. According to one aspect of this invention, the actual cards are provided with some indicia which can be electronically read. In this manner, the cards can be automatically tallied and displayed by simply feeding them through a card reader. Alternatively, each individual player can be provided with an opportunity to obtain his own indication of some or all of the previously discarded cards. Therefore, either a common display can be provided or each player can be provided with his own display. Providing players with their own displays will facilitate requiring additional payments or other player-specific criteria.
Various embodiments of the present invention provide a player with a discernable indication of which cards have been discarded, or, alternatively, which cards have been dealt from the collection of cards from which cards are dealt, e.g., a multi-deck card shoe. If the display is set to indicate all previously discarded cards then cards presently being utilized in a hand being played will not be shown in the discarded card screen. Alternatively, in order to provide a player with a single, viewable location for determining cards which are no longer in the card deck and which therefore can not be drawn, an alternative embodiment of the present invention lists all cards which have been dealt in the discard display. While a visible display is the preferred manner of indicating to players the number of cards of each type which have already been discarded, it is also within the scope of the present invention to provide this information to players in other forms, e.g. audibly.
According to the method of play of this illustrated embodiment, the particular hand which is being played is highlighted or otherwise provided with some clear indicia so that the player can readily determine which hand is being played. For example, the hand being played can flash or be illuminated brighter or with different colors from the other hands. A hand remains in play, according to this illustrated embodiment, until a player goes “BUST” i.e., goes over twenty-one, or until the “STAND” button has been touched. Touch screen areas 24-28 provide a player with the option to reshuffle by touching “RESHUFFLE” area 24, to stand by touching “STAND” area 25, to take another card by touching “HIT” area 26, to split the hand by touching “SPLIT” area 27, or to double down by touching “DOUBLE DOWN” area 28. The illustrated display screen 10 also comprises wager display 35 area which indicates the number of credits still available, the amount wagered during a game, and the number of credits won during a given game.
Illustrated display screen also advantageously comprises a discarded card display 40. The illustrated discarded card area 40 comprises twenty four rows and thirteen columns. The twenty four rows provide one row for each card denomination for six decks of cards. Those skilled in the art will appreciate that each deck of cards comprises four cards of each denomination, for example, four Jacks. This illustrated embodiment is designed for use with a six deck shoe simulation, therefore, it is possible to have twenty four cards of each value discarded. The thirteen columns represent a single column for each card denomination. According to this illustrated embodiment, there is no distinction between cards of different suits. From the present description, those skilled in the art will appreciate that for other types of card games, it may be desirable to provide an indication of particular suits or particular cards of a particular suit that have been discarded.
Therefore, in this illustrated embodiment, cards are only listed in the discarded card area after a particular deal is over and the cards have been discarded. It is also within the scope of the present invention to discard a particular hand after that particular hand has gone bust. According to this illustrated embodiment, only cards which have been discarded are shown in the discarded card area 40. As noted above, it is also within the scope of the present invention to provide a display which lists all cards which have been dealt. In an embodiment which indicates all cards once the cards have been dealt, the dealers face down card would not preferably be indicated.
While this illustrated embodiment of the present invention comprises a discarded card area on the same screen as the game being played and the input areas, it is also within the scope of the present invention to have the “DISCARDED CARD” display or a “DEALT CARD” display separate from the game display.
As used herein, the term “DISCARDED” is not limited to cards which have been displayed and then not used in any card hand. The term “DISCARDED” as used herein includes all cards which have been used in previous hands, whether those cards were used in the hand of a player or a dealer, or even if those cards were not incorporated or used in any hand of a game participant. The term “CARD INDICIA” is used to indicate images of playing cards as well as the playing cards themselves. Therefore, the term “CARD INDICIA” refers to both visual displays of card images on a screen as well as cards placed on a table game. The selection of cards displayed in gaming device embodiments of the present invention is preferably determined randomly.
Even though the card images are determined randomly, the present invention is not limited nor dependent upon any one particular type of electronic embodiment or circuitry. While one or more random number generators or other random signal generators can be utilized with various embodiments of the present invention and those devices may generate signals which are subsequently converted into signals producing card indicia on a display screen, for simplicity, all such signals, whether subsequent to or prior to conversion to a signal which creates the image of a playing card on a screen are referred to herein as “CARD INDICIA”.
In a table game format of a conventional Blackjack game, those skilled in the art will appreciate that a card shoe may typically comprise a plurality of card decks, for example, six decks of cards. A “cut card” is typically inserted into the card shoe and then cards forward of the “cut card” are then dealt. When the dealer gets down to the “cut card” the cards are reshuffled. According to the various embodiments of the present invention, the use of a “cut card” can be simulated. When a “cut card” is used, the pool of cards from which any particular displayed card is chosen will be a subset of the total number of card indicia in the number of decks utilized.
From the present description, those skilled in the art will appreciate that after playing a game of the present invention for awhile and as the number of displayed discarded cards increases, players will have an advantage since they will have a better idea of cards which may be dealt. In order to avoid providing this advantage to undeserving players, e.g., a different player who uses a gaming device after a first player had played for awhile, the gaming devices of the present invention are preferably designed to reset and reshuffle if a predetermined time span has elapsed between the end of one game and the start of another game. For example, if a gaming device sits idle for thirty seconds, then the game may automatically reset and reshuffle. The length of time can be set as desired by the manufacture or its designee. This feature will also advantageously tend to hold players at a specific gaming device once the number of cards in the discarded card display becomes significant.
As noted above, it is also within the scope of the present invention to provide an indication of all cards dealt up to any given time, rather than just the cards which were dealt in previous games/hands. If the display indicates which cards have been dealt, then a player has a single, convenient location to view for an indication of possible cards to be drawn and would not have to add the cards displayed on the display screen to the cards shown on the discarded card screen.
The touch screen display of the embodiment shown in
In the embodiment shown in
A keno board used with another embodiment of the present invention. According to this embodiment, a first keno-type game is played wherein a plurality of numbers are selected randomly. Prior to the selection and display of those numbers, players are provided with an opportunity to wager on the numbers to be selected. For example, a typical keno game may provide a payout after selecting two to ten numbers to all players who have matched at least some predetermined number of the randomly selected numbers. According to this embodiment of the present invention, after a first keno game has been played and certain numbers have been used or eliminated for subsequent play, one or more players are provided with the opportunity to wager on the remaining numbers. Those skilled in the art will appreciate that the players will have an increased chance of winning on the second or other subsequent games since the total pool of available numbers is reduced by the number of numbers used in the previous game(s).
Additionally or alternatively, if desired, each player station can be provided with a discarded card or dealt card display as shown in FIG. 6 and players can be provided with visible access to the discard display depending upon certain criteria, or, if desired, randomly. For example, this embodiment of the present invention can provide players visual access to the discard display only if the players wager the maximum amount permitted. Alternatively, the players may be required to pay a fee, for example, five dollars prior to a wagering session which can be for a pre-determined length of time, for example two hours, if the player wishes access to the discard display. Alternatively, a common or individual discard display can be made visually accessible to one or more players in response to the success or lack of success that players have attained while playing the card game, e.g. Blackjack in this illustrated embodiment. For example, if no players win during two deals, then the discard display may be activated for the subsequent deal or until a player wins. Alternatively, the discard display may be actuated for a predetermined length of time or for a predetermined number of deals every time one or some other predetermined number of players attains a Blackjack.
The electronic and mechanical details of the discarded card reader 90 are not provided herein, but are well within the scope of one of ordinary skill in the art. For example, the playing cards can be provided with a machine readable code on the same side which displays the denomination and suit. Such a code would be readable by discard reader 90.
While the illustrated card game embodiments have been directed to Blackjack card games, other card or non-card games can be played utilizing the present invention. For example, draw poker in various forms could be played using aspects of the present invention.
According to still other embodiments of the present invention, other types of games wherein items or values are drawn from predetermined collections can also enjoy the benefits of the present invention.
The present invention is believed to be particularly attractive to players since the disclosed embodiments of the present invention provide ready access to information which was previously unavailable or difficult to remember.
