Abstract:
The present invention relates to a single actual player playing a multiplayer card selection game against a set of virtual players. It creates a new game that uses the card selection feature of inventor&#39;s previous games, but has a very different goal and structure than those games. Instead of the actual player trying to build the best hand with no guarantee of success, the actual player tries to use card selection undo followed by reselecting more optimal cards the fewest number of times to build the best hand playing against the virtual players. In addition, actual players can compete against each other to determine who is best at playing the same game against the same number of virtual players. The winner is the actual player who uses undo card selection the fewest number of times in building the best hand playing against his/her set of virtual opponents.

Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
       [0001]    This application is based on provisional application Ser. No. 61/574,430, filed on Aug. 2, 2011, entitled COMPUTER-BASED, MULTIPLAYER CARD SELECTION GAME THAT USES CARD SELECTION UNDO TO DETERMINE SCORING. 
     
    
     TECHNICAL FIELD 
       [0002]    The present invention relates to computerized, multiplayer, card selection games involving a single actual player playing against a set of virtual players and, in particular, to a game where the goal of the actual player is to obtain the best hand by undoing card selections and reselecting more optimal cards the fewest number of times compared to other actual players. 
       BACKGROUND 
       [0003]    Historically, the hundreds of different card games played around the world like poker have all been based on random dealing thru the use of shuffling. However, with the advent of computers, the present inventor, Arthur Pfeiffer, previously invented a new way of dealing cards in a multiplayer game where random dealing to individual players is replaced by player card selection. With this method, on at least one round, each player first privately selects a desired card from the same face up deck of playing cards. Once every player has selected a card, the game management system then determines what card each player is dealt. A player whose selection is in conflict with that of another player is dealt a null card that has no value. Otherwise, the player is dealt the card he/she selected. 
         [0004]    U.S. Pat. No. 4,662,637 to Arthur Pfeiffer discloses a method of playing a card game in which the players select desired cards from a deck of playing cards, which are delivered to players unless a player requests the same card that another player has requested during the same round of play or was dealt on a previous round, in which case a null card, having no value in determining the outcome of the game, is delivered to the requesting player. Poker scoring rules are used to determine the outcome of the game. 
         [0005]    U.S. Pat. No. 4,667,959 to A. Pfeiffer discloses a selector unit and card-storage carousel for playing a card game disclosed in U.S. Pat. No. 4,662,637. 
         [0006]    Many games are now played on computing devices and the concept of playing card games over a network such as the Internet is well known. Patents have been granted to new card games that include claims that cover playing the game over the Internet. For instance, U.S. Pat. No. 5,951,012 discloses a poker game where the amount of successive wagers is pre-established by the players; this game may be played on the Internet. Similarly, U.S. Pat. No. 6,012,720 discloses, “enhanced features” of the card game Double Hand; this game may also be played on the Internet. 
         [0007]    U.S. Pat. No. 6,679,777 B2 and related reissue U.S. Pat. No. RE41,331 E to Arthur Pfeiffer, both incorporated herein by reference, disclose a method of playing network-based multiplayer card selection games on computing devices that can communicate with each other on the Internet, over a local area network, or by other means such as Bluetooth or Wi-Fi. These games follow the scoring rules of poker and can involve both actual and virtual players. When one actual player plays against a set of virtual players, a single computing device can be used that also contains the server software for network communication. On each round each player first privately selects a card from the same deck of playing cards. In one embodiment, on the same computing device, after each player has made his/her card selection, a player is dealt a null card that has no value, if that player&#39;s selected card is the same as a card selected by another player on the same or previous round. Otherwise, that player is dealt his/her selected card. In another embodiment, on the same computing device, after each player has privately made his/her card selection, that player is dealt a null card that has no value if that player&#39;s selected card is the same as a card selected by another player on the same round or was dealt to a player on a previous round. Otherwise, that player is dealt his/her selected card. 
         [0008]    U.S. Pat. No. 7,717,783 B2 to Arthur Pfeiffer, incorporated herein by reference, discloses a method of playing multiplayer card selection games on one or more computing devices that follow the scoring rules of poker or, more generally, that follow predetermined rules of play, and can involve both actual and virtual players. These games use a mixture of community cards and cards selected by the players. The community cards are randomly dealt first from a deck of playing cards. All the players share the same community cards. After the community cards are dealt there are one or more rounds where each player privately selects a desired card from the same deck of playing cards face up. After all the players have made their card selection in a round, each player is dealt a card following the rules described in reissue U.S. Pat. No. RE41,331 E. 
         [0009]    U.S. Pat. No. 7,806,408 B2 to Arthur Pfeiffer, incorporated herein by reference, discloses a computerized table with display screens for playing a card selection game between real players disclosed in U.S. Pat. No. 7,717,783 B2. The table system may contain electronic sensors for sensing the identity of an actual card or the value of chip, in which case actual cards and/or betting chips containing radio frequency identification (RFID) chips can be used. 
         [0010]    U.S. patent application Ser. No. 12/731,119 to Arthur Pfeiffer, incorporated herein by reference, discloses a method of playing computerized multiplayer card selection games that follow the scoring rules of poker or, more generally, that follow predetermined rules of play, in which a fixed deck of playing cards is used first either for randomly dealt community cards that are shared by all the players, or for one or more rounds where players select cards. Then a second deck of playing cards is generated that has fewer cards than the first deck and is composed of cards randomly selected from the first deck of playing cards. If community cards are used, the number of community cards plus the number of cards in the second deck of playing cards excluding any community cards is less than the number of cards in the fixed first deck of playing cards. There are then one or more rounds where each player privately selects a desired card from the second deck of playing cards, excluding community cards. After all the players have made their card selection in a round, each player is dealt a card following the rules described in reissue U.S. Pat. No. RE41,331 E. 
         [0011]    The above-described patents and patent application by the present inventor each have claims regarding a single actual player playing a card selection game against a set of virtual players, where, in a round where players select their cards, each player first privately selects a card from the same deck of playing cards face up, and after every player has selected a card, each player is either dealt a null card when his/her selection is in conflict with that of another player, or otherwise is dealt his/her selected card. The goal and purpose of such games is for the actual player to try to win by building the best hand of all the players, according to predetermined rules of play. There may be situations where more than one player has the best hand. However, none of these games guarantee that the actual player will build the best hand and be the winner, for that defeats the purpose of the games themselves. In fact, in general, none of the above-described games by the present inventor provide the guarantee that a particular player, actual or virtual, will build the best hand. 
       SUMMARY 
       [0012]    The present invention relates to card selection games of the type described above involving a single actual player playing against one or more virtual players. However, it modifies the structure of the above-described games by the present inventor to create a new game where the goal of the actual player is to use a “card selection undo” button the fewest number of times in order to build the best hand, according to predetermined rules of play. In the present invention the actual player must get the best hand, and in doing so tries to minimize the number of times he/she uses card selection undo. 
         [0013]    The use of card selection undo has no meaning in a standard multiplayer card game, for in those games there is no card selection, certainly not as described in the present inventor&#39;s pending patent or granted patents referenced above. Also, since cards in standard multiplayer card games are randomly dealt, even if undo were introduced into those games, there is no way to control the cards dealt to the different players to insure that any particular player will get the best hand. Some standard multiplayer card games like draw poker provide players with a chance to improve their hand by discarding some of their cards. However, the replacements are also randomly dealt, so the above analysis also applies to their use. Furthermore, the purpose of these standard multiplayer card games, even when involving a single actual player playing against a set of virtual players, is for the actual player to try to get the best hand without any way of being assured that he/she will succeed in getting the best hand. 
         [0014]    The present invention relates to a single actual player playing a multiplayer card selection game against a set of virtual players. It creates a new game that uses the card selection feature of inventor&#39;s previous games, but has a very different goal and structure than those games. Instead of the actual player trying to build the best hand with no guarantee of success, the actual player tries to use card selection undo the fewest number of times possible in order to build the best hand playing against the virtual players. The new embodiments offer substantial improvements over the games disclosed by the inventor in U.S. Pat. No. 4,662,637, U.S. Pat. No. 4,667,959, U.S. Pat. No. 6,679,777 B2, U.S. Pat. No. RE41,331 E, U.S. Pat. No. 7,717,783 B2 and U.S. patent application Ser. No. 12/731,119, all incorporated herein by reference.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0043]    The present invention relates to card selection games where a single actual player plays against one or more virtual players. It modifies the structure of the above-described games by the present inventor to create a new game where the goal of the actual player is to use card selection undo the fewest number of times in order to build the best hand compared to those of the virtual players, according to the scoring rules of poker, or more generally, according to predetermined rules of play. In the present invention the actual player must build the best hand, and in doing so tries to minimize the number of times he/she uses card selection undo. 
         [0044]    In the embodiments of the present invention described herein, after a round of player card selection has been completed and each player has either been dealt his/her card selection or a null card, whichever is appropriate, the actual player has the option to undo his/her card selection for the completed round. If the actual player chooses this option, then play reverts to the start of the card selection round just completed, with each player&#39;s previous selection and associated dealt card cancelled. Each player then gets to make his/her card selection anew for the old previously completed round, which is now the current card selection round. Furthermore, if the new current card selection round was preceded by a completed card selection round, the actual player has the option to undo that round and revert to its start. The actual player can repeat this process until there is no previously completed card selection round. Also, if the actual player does not have the best hand after each player has been dealt the predetermined number of card selection round cards for the game to be over, play then continues and reverts to the start of the card selection round just completed. In addition, the last card dealt to each player is not necessarily revealed to any player when the actual player does not have the best hand after the predetermined number of card selection rounds has been completed. 
         [0045]    In one embodiment of the invention the games follow the scoring rules of poker. In another embodiment the games follow predetermined rules of play. 
         [0046]    In one embodiment of the invention, after all players have privately selected a card in a card selection round, a null card, which has no value in determining the outcome of the game, is delivered to players who request the same card as another player has requested on the current round or a previous round. Otherwise, a player is dealt his/her selected card. In another embodiment, after all players have selected a card in a card selection round, a null card is delivered to players who request the same card as another player has requested on the current round or has been dealt to a player on a previous round. Otherwise, a player is dealt his/her selected card. 
         [0047]    One embodiment of the invention has one or more community cards randomly dealt from a deck of playing cards, usable by any player in building a hand, according to predetermined rules and followed by one or more rounds of player card selection from the same deck of playing cards. Another embodiment only has one or more rounds of player card selection from a deck of playing cards. Another embodiment has one or more rounds of cards randomly dealt to each player from a deck of playing cards followed by one or more rounds of player card selection from the same deck of playing cards. 
         [0048]    One embodiment of the invention has one or more community cards randomly dealt from a first deck of playing cards, usable by any player in building a hand, according to predetermined rules. Then a second deck of cards is generated that is composed of cards randomly selected from the first deck of playing cards excluding the community cards, where the number of cards in the second deck plus the number of community cards is less than the number of cards in the first deck. One or more rounds of player card selection from the second deck of cards then follow. Another embodiment has one or more community cards randomly dealt from a first deck of playing cards, usable by any player in building a hand, according to predetermined rules. Then a second deck of cards is generated that is composed of the community cards plus other cards randomly selected from the first deck of playing cards, where the number of cards in the second deck is less than the number of cards in the first deck. One or more rounds of player card selection from the second deck of cards then follow. 
         [0049]    One embodiment of the invention has one or more rounds of player card selection from a first deck of playing cards. Then a second deck of cards is generated that has fewer cards than the first deck and is composed of cards randomly selected from the first deck plus any cards selected by the players from the first deck of playing cards. Then there are one or more rounds of player card selection from the second deck of cards. 
         [0050]    One embodiment of the invention has a single actual player playing against one or more virtual players on the same computing device. Another embodiment has two or more actual players competing in a tournament, each with a computing device and each playing the same game against the same number of virtual players on his/her computing device. For each game having community cards, the same community cards are used on each computing device. Also, each game uses the same deck of playing cards for player card selection on each computing device and each game has the same number of card selection rounds on each computing device. In this embodiment the actual player that uses card selection undo the fewest number of times in building the best hand playing against his/her respective virtual players on his/her computing device is declared the tournament winner. 
         [0051]    Several different operating environments are suitable for playing the game when more than one actual player is involved. The game can be played over the Internet or over a local area network. Using handheld computing devices like smartphones, such as the iPhone, the game can be played using Bluetooth or Wi-Fi for communication. In general, any operating environment that accommodates communication between computing devices or involves display terminals linked to a central computing device over a network can be used to play this invention. 
         [0052]    In one embodiment of the invention two or more actual players, each using a separate computing device, play the same game against the same number of virtual players on his/her computing device. Game management software directs and facilitates play, controls the virtual players and keeps track of the number of times and when each actual player elects card selection undo. The game management software maintains a level playing field for the actual players. It insures that when each card selection and each use of card selection undo for 2 or more actual players is sequentially identical, then all the card selections for each set of their corresponding virtual players are also sequentially identical. The game management software also insures that when community cards are dealt in a hand, they are the same for all players. It also insures that each player uses the same deck of playing cards for card selection and that each player plays the same number of predetermined card selection rounds for the game to be over. 
         [0053]    The embodiments in inventor&#39;s referenced patents or patent application that involve one actual player playing against one or more virtual players also constitute other embodiments of the current invention. 
         [0054]    For all of the embodiments of the invention, the computing device used by an actual player has a display screen. Depending upon the type of display screen and computing device, when required, an actual player can point to and select on the display screen a desired card from the card selection deck. This is accomplished by means of a touch screen or keyboard, or when a cursor is involved, by means of a mouse, trackball or some other similar selection device. 
         [0055]    The various described or referenced embodiments may be combined within one game. For instance, prior to any card selection rounds, there can be at least one community card dealt and at least one round where each player receives a randomly dealt card. 
         [0056]    Twenty-eight screen drawings are included ( FIGS. 1A-O ,  FIGS. 2A-F ,  FIGS. 3A-G ) that all show the display screen of an actual player playing directly against a set of virtual players on the same computing device with a mouse for card and button selection. All of the games depicted in these drawings involve player card selection from a displayed deck of playing cards, where after all players in a card selection round have privately selected their card from the deck, each player is dealt a no-value null card when that player either selects a card that is the same as one selected by another player in the current round or is the same as a card dealt to another player in a previous round. Otherwise, the player is dealt his/her selected card. Note that in these drawings a large X on a dealt card indicates that it is a null card. Except when the game is over, the suit or rank of the selected card is not displayed on the null cards dealt to virtual players. Also, all cards in the displayed deck that the actual player knows have already been dealt are shadowed out. 
         [0057]    Set one ( FIGS. 1A-O ) shows fifteen drawings for a card selection game involving an actual player playing against two virtual players. Three community cards are first randomly dealt followed by 4 rounds of player card selection from a deck of playing cards displayed face up. The community cards are usable by all players in forming a hand. Cards are dealt face down in the first card selection round and face up in each of the next three rounds. In these drawings the displayed deck from which the players select cards has fewer cards than a standard 52-card deck of playing cards and contains the community cards, which are not selectable. A card selection game using community cards could also be played with a 52-card deck or some other kind of deck of playing cards for player card selection, with or without the community cards included in the displayed deck. 
         [0058]      FIGS. 1A-O  are divided into 2 subsets. The first subset  FIGS. 1A-I  contains nine drawings and represents a first actual player NAME 1  playing against 2 virtual players NAME 2  and NAME 3 . The first subset  FIGS. 1A-I  can be considered alone or in conjunction with the second subset  FIG. 1J-O . 
         [0059]      FIG. 1A  shows NAME 1 &#39;s screen  10  for a single actual player, NAME 1   12 , playing against two virtual players, NAME 2   14  and NAME 3   16 . Three community cards, diamond six  18 , spade queen  20 , spade four  22 , usable by all players in forming a hand, have been dealt face up. All the players are about to make their first card selection from the same displayed deck  24  that also displays the community cards shadowed out  26  to indicate that they have already been dealt. The club queen  28  in the card selection deck is raised to indicate that NAME 1  has clicked on it as his/her current selection choice on this first card selection round. Once NAME 1  is sure of his choice, he/she will click on the Confirm button  30  to execute that choice for his/her first card selection. NAME 1 &#39;s current card selection Undo Count of zero is displayed  32 . 
         [0060]      FIG. 1B  shows NAME 1 &#39;s screen  40  at the start of the second card selection round. Since cards are dealt face down in the first card selection round, only NAME 1 &#39;s first dealt card, the club queen  42  is displayed, and both NAME 2 &#39;s first dealt card  44  and NAME 3 &#39;s first dealt card  46  are dealt face down. The club queen is shadowed out in the displayed card selection deck  48  because NAME 1  knows it has already been dealt. Now that at least one card has been selected and dealt to each player, NAME 1  has the option of canceling the previous card selection round for everyone by clicking on the Undo button  50 . The heart queen in the card selection deck is raised  52  to indicate that NAME 1  has clicked on it as the current candidate for card selection on this second card selection round. 
         [0061]      FIG. 1C  shows NAME 1 &#39;s screen  60  at the start of the fourth card selection round. So far, three cards have been dealt to each player. In the second card selection round, NAME 1  selected the heart queen, got blocked and was dealt a null card  62 , NAME 2  selected and was dealt the spade nine  64  and NAME 3  got blocked and was dealt a null card  66 . In these card selection games, when a round is dealt face up, a player only sees the suit and rank of a card dealt to another player when that player&#39;s selection hasn&#39;t been blocked. In this instance, NAME 3 &#39;s second card selection was blocked and therefore, NAME 1  does not see its suit and rank and neither does NAME 2 . In the third card selection round, NAME 1  selected the diamond queen, got blocked and was dealt a null card  68 , NAME 2  got blocked and was dealt a null card  70  and NAME 3  selected and was dealt the heart four  72 . Note that in the card selection deck both the spade nine and heart four are now shadowed out  74 . Note also that neither the heart queen nor the diamond queen in the deck is shadowed out  76 . Though NAME 1  selected each of these cards on a previous round, they were blocked and not dealt to NAME 1 . Also, NAME 1  has no indication that either the heart queen or the diamond queen was dealt to any of the other players. Therefore, either card can be selected again by NAME 1  in the current selection round. At this point NAME 1  has not cancelled any previously dealt cards, so the Undo Count is still zero  78 . NAME 1  now decides he/she won&#39;t be able to get the best hand with his/her current dealt cards, so NAME 1  clicks on the Undo button  80  to cancel the previous third card selection round for all the players. 
         [0062]      FIG. 1D  shows NAME 1 &#39;s screen  90  at the start of the new third card selection round, after NAME 1  just clicked on the Undo button in the fourth card selection round to cancel the cards dealt to the players in the third card selection round. Note the changes that have just taken place. The Undo Count  92  has been incremented and is now 1. Each player is back to only having two cards dealt to him or her, which are the same as they were prior to the card selection undo. For NAME 1  the first dealt card is the club queen  96  and the second dealt card is the blocked heart queen  102 . For NAME 2  the first dealt card is face down  98  and the second dealt card is the spade nine  104 . For NAME 3  the first dealt card is face down  100  and the second dealt card is a null card  106 . As a result of the cancellation, the heart four in the card selection deck  94  is no longer shadowed out for it no longer has been dealt to NAME 3  and is therefore free to be selected. NAME 1  still thinks he/she won&#39;t be able to get the best hand with his/her current dealt cards, so NAME 1  clicks on the Undo button  108  to cancel the second card selection round for all the players. 
         [0063]      FIG. 1E  shows NAME 1 &#39;s screen  110  at the start of the second card selection round, after NAME 1  just clicked on the Undo button in the third card selection round to cancel the cards dealt to the players in the second card selection round. The Undo Count  112  has been incremented and is now 2. Each player is back to only having one card dealt to him or her, which is the same as it was prior to the card selection undos. For NAME 1  the first dealt card is the club queen  118 . For NAME 2  the first dealt card is face down  120 . For NAME 3  the first dealt card is face down  122 . As a result of the cancellation, the spade nine is no longer shadowed out  114  in the card selection deck for it no longer has been dealt to NAME 2  and is therefore free to be selected. The diamond queen in the card selection deck is raised  116  to indicate that NAME 1  has clicked on it as his/her current card choice on this second card selection round. NAME 1  then clicks on the Confirm button  128  to execute that choice for his/her second card selection. 
         [0064]      FIG. 1F  shows NAME 1 &#39;s screen  130  at the start of the third card selection round, after all the players privately selected and then were dealt their second card. This time in the second card selection round, NAME 1  selected and was dealt the diamond queen  132 , NAME 2  selected and was dealt the spade nine  134  and NAME 3  selected and was dealt the heart queen  136 . Consequently, the diamond queen, spade nine and heart queen are all shadowed out in the card selection deck  138 . The club four in the card selection deck is raised  140  to indicate that NAME 1  has clicked on it as his/her current card choice on this third card selection round. NAME 1  then clicks on the Confirm button  142  to execute that choice for his/her third card selection. 
         [0065]      FIG. 1G  shows NAME 1 &#39;s screen  150  at the start of the fourth card selection round, after all the players privately selected and then were dealt their third card. This time in the third card selection round NAME 1  selected the club four, got blocked and was dealt a null card  152 , NAME 2  got blocked and was dealt a null card  154  and NAME 3  got blocked and was dealt a null card  156 . Though NAME 1 &#39;s third card selection of the club four was blocked  152 , it still can be selected again in this current fourth round since it might not have been dealt previously. NAME 1  decides to pick the club four  158  again and then clicks on the Confirm button  160  to execute that choice for his/her fourth card selection. 
         [0066]      FIG. 1H  shows NAME 1 &#39;s screen  170  at the start of the fourth card selection round, after it was determined that NAME 1 &#39;s previous fourth round card selection of the club four  172  did not produce the best hand. Since the previous card selection was made on the final card selection round, NAME 1  is informed that he/she did not have the best hand  174 . Since the goal of the game is for NAME 1  to get the best hand with the fewest number of Undos, the cards dealt to the players in the previous fourth card selection round are canceled, the Undo Count  176  is incremented to 3 and play reverts again to the start of the fourth card selection round. NAME 1  now selects the heart four  178  and then clicks on the Confirm button  180  to execute that choice for his/her fourth card selection. 
         [0067]      FIG. 1I  shows NAME 1 &#39;s screen  190  when the game is over. It displays the suit and rank of every card selected by each player on every card selection round, regardless of whether the associated dealt card was dealt face down or was a null card. In the first card selection round, NAME 2  selected and was dealt the spade seven  196  and NAME 3  selected and was dealt the club four  204 . In the third round, NAME 2  selected the heart four, got blocked and was dealt the null card  198  and NAME 3  also selected the heart four, also got blocked and was dealt the null card  206 . In the fourth and final round, NAME 1  selected and was dealt the heart four  192  to give NAME 1  a full house  194 , NAME 2  selected and was dealt the spade five  200  to give NAME 2  a spade flush  202  and NAME 3  selected the club queen but got blocked and was dealt the null card  208  to give NAME 3  two pair  210 . NAME 1  has the best hand  212  and a final Undo Count of three  214 . 
         [0068]    The second subset  FIGS. 1J-O  contains six screen drawings of a second actual player playing the same game against two virtual players, which was played by the first actual player. Taken together with  FIGS. 1A-I  they represents 2 actual players, NAME 1  and NAME 4  indirectly playing against each other in a tournament. The tournament winner is the actual player who uses card selection undo the fewest number of times in building the best hand directly playing against his/her respective virtual players. 
         [0069]      FIG. 1J  shows NAME 4 &#39;s screen  310  at the start of the same game played by NAME 1 . It shows a single actual player, NAME 4   312 , playing against two virtual players, NAME 5   314  and NAME 6   316 . The same three community cards, diamond six  318 , spade queen  320 , spade four  322 , have been dealt face up. They are the same community cards dealt in  FIG. 1A  ( 18 ,  20 ,  22 ). All the players are about to make their first card selection from the displayed deck  324  that also displays the community cards shadowed out  326  and has the same composition as the displayed deck  24  in  FIG. 1A . The Undo Count is zero  332 . NAME 4  has selected the club four  328  and confirmed it by clicking on the Confirm button  330 . 
         [0070]      FIG. 1K  shows NAME 4 &#39;s screen  340  at the start of the third card selection round. So far, two cards have been dealt to each player. In the first card selection round, NAME 4  selected the club four, got blocked and was dealt a null card  344 , NAME 5 &#39;s card was dealt face down  346  and NAME 6 &#39;s card was dealt face down  348 . In the second card selection round, NAME 4  selected the heart queen, got blocked and was dealt a null card  350 , NAME 5  selected and was dealt the spade nine  352  and NAME 6  got blocked and was dealt a null card  354 . The spade nine is now shadowed out  356  in the card selection deck. At this point NAME 4  has not cancelled any previously dealt cards, so the Undo Count is still zero  342 . However, NAME 4  decides he/she won&#39;t be able to get the best hand with his/her current dealt cards, so NAME 4  clicks on the Undo button  358  to cancel the previous second card selection round. 
         [0071]      FIG. 1L  shows NAME 4 &#39;s screen  370  at the start of the first card selection round, after NAME 4  clicked on the Undo button in the third card selection round and then immediately again in the second card selection round. The Undo Count is now two  372  at the new start of the first card selection round. NAME 4  has now selected the club queen  374  as his/her new first card selection and confirmed it by clicking on the Confirm button  376 . 
         [0072]      FIG. 1M  shows NAME 4 &#39;s screen  380  after four rounds of card selection. It displays the suit and rank of every card selected by each player on every card selection round, regardless of whether the associated dealt card was dealt face down or was a null card. NAME 4  selected and was dealt the heart four in the fourth card selection round  384  to give him/her a full house  386 . NAME 5  selected and was dealt the spade seven in the first card selection round  388  and selected and was dealt the spade five in the fourth card selection round  390  to give him/her a spade flush  392 .

         [0073]    For the same community cards and the same card selection deck,  FIG. 1I  shows that actual player NAME 1 , with a card selection Undo Count of three  214 , has gotten the best hand  212  playing against virtual players NAME 2  and NAME 3 , and  FIG. 1M  shows that actual player NAME 4 , with a card selection Undo Count of two  382 , has gotten the best hand  798  playing against virtual players NAME 5  and NAME 6 . 
         [0074]      FIG. 1N  shows NAME 1 &#39;s screen  400  at the end of the tournament between actual players NAME 1  and NAME 4  playing the same game against their respective virtual players. The tournament winner is the actual player, NAME 1  or NAME 4  who has used Undo Count the fewest number of times to build the best hand. It shows that NAME 4  is the winner with the smallest Undo Count of 2 and displays the Undo Count of each actual player  402 . 
         [0075]      FIG. 1O  shows NAME 4 &#39;s screen  410  at the end of the tournament. It shows that NAME 4  is the winner with the smallest Undo Count of 2 and displays the Undo Count of each actual player  412 . 
         [0076]    Set two ( FIGS. 2A-F ) shows 6 screen drawings for a card selection game, with no community cards, involving one actual player playing against one virtual player. There are 6 rounds of player card selection with the first round dealt face down and the next five rounds dealt face up. In the first round, players select from a standard 52-card first deck of playing cards, and in rounds two thru six, from a smaller second deck of cards. The second deck is composed of cards selected in the first round and cards randomly selected from the first deck. Card selection undo only applies to the second deck and can only be used to cancel cards dealt to the players in rounds  2  thru  6 . 
         [0077]      FIG. 2A  shows NAME 1 &#39;s screen  510  for a single actual player, NAME 1   512 , playing against one virtual player, NAME 2   514 .

In the first card selection round, NAME 1  selected and was dealt the diamond ace  532  and NAME 2  was dealt a card face down  534 . The diamond ace is shadowed out  538  in the second card selection deck, since NAME 1  knows that it has already been dealt. NAME 1 &#39;s current card selection Undo Count of zero is displayed  540 . The spade ace in the card selection deck is raised  542  to indicate that NAME 1  has clicked on it as his/her current card choice on this second card selection round. NAME 1  then clicks on the Confirm button  544  to execute that choice. 
         [0079]      FIG. 2C  shows NAME 1 &#39;s screen  550  at the start of the fifth card selection round. So far, four cards have been dealt to each player.

         [0081]      FIG. 2E  shows NAME 1 &#39;s screen  590  at the start of the sixth card selection round, after it was determined that NAME 1 &#39;s previous card selection of the spade ten did not produce the best hand. Since the previous card selection was made on the final card selection round, NAME 1  is informed that he/she did not have the best hand  592 . Since the goal of the game is for NAME 1  to get the best hand with the fewest number of Undos, the cards dealt to the players in the previous sixth card selection round are canceled, the Undo Count  594  is incremented to 1 and play reverts again to the start of the sixth card selection round.

In the sixth and final round, NAME 1  selected the heart nine again, but again got blocked and was dealt a null card  616 , and NAME 2  selected the heart nine again, but again got blocked and was dealt a null card  618 . This gave NAME 1  a final hand of three of a kind  620  and NAME 2  a final hand of only queen high  622 . As a result, NAME 1  has the best hand  624  and a final Undo Count of one  626 . 
         [0083]    Set three ( FIGS. 3A-G ) shows 7 screen drawings for a card selection game, with no community cards, involving one actual player playing against one virtual player. There are 6 rounds of player card selection with the first round dealt face down and the next five rounds dealt face up. In every round, players select from the same deck of playing cards. Set three ( FIGS. 3A-G ) differs from set two ( FIGS. 2A-F ) in that only one deck of playing cards is used for card selection in set three and card selection undo can be used to cancel cards dealt to the players in any of the rounds  1  thru  6 . 
         [0084]      FIG. 3A  shows NAME 1 &#39;s screen  710  for a single actual player, NAME 1   712 , playing against one virtual player, NAME 2   714 .

         [0087]      FIG. 3D  shows NAME 1 &#39;s screen  770  at the start of the sixth card selection round again after it was determined that NAME 1 &#39;s previous card selection of the heart queen did not produce the best hand. Since the previous card selection was made on the final card selection round, NAME 1  is informed that he/she did not have the best hand  772 . Since the goal of the game is for NAME 1  to get the best hand with the fewest number of Undos, the cards dealt to the players in the previous sixth card selection round are canceled, the Undo Count  774  is incremented to 1 and play reverts again to the start of the sixth card selection round. NAME 1  decides that he/she won&#39;t be able to get the best hand with his/her current dealt cards, so NAME 1  clicks on the Undo button  778  to cancel the fifth card selection round for all the players. 
         [0088]      FIG. 3E  shows NAME 1 &#39;s screen  780  at the start of the fifth card selection round, after NAME 1  just clicked on the Undo button in the sixth card selection round to cancel the cards dealt to the players in the fifth card selection round.

As a result of the cancellation, the spade ten  784  and heart nine  786  are no longer shadowed out in the card selection deck. The heart nine in the card selection deck is raised  786  to indicate that NAME 1  has clicked on it as his/her current card choice on this fifth card selection round. NAME 1  then clicks on the Confirm button  788  to execute that choice for his/her fifth dealt card. 
         [0089]      FIG. 3F  shows NAME 1 &#39;s screen  790  at the start of the sixth card selection round, after all the players privately selected and then were dealt their fifth card. In the fifth card selection round, NAME 1  selected the heart nine, got blocked and was dealt a null card  792  and NAME 2  also got blocked and was dealt a null card  794 . To try to block NAME 2  from getting a straight flush, NAME 1  has selected the heart nine again  796  and confirmed that choice as his/her sixth card selection by clicking on the Confirm button  798 . 
         [0090]      FIG. 3G  shows NAME 1 &#39;s screen  800  when the game is over. It displays the suit and rank of every card selected by each player on every card selection round, regardless of whether the associated dealt card was dealt face down or was a null card. In the first card selection round, NAME 2  selected and was dealt the heart queen  802 . In the fifth card selection round, NAME 2  selected the heart nine, got blocked and was dealt the null card  804 . In the sixth and final round, NAME 1  selected the heart nine again, got blocked and was dealt a null card  806  and NAME 2  selected the heart nine again but also got blocked and was dealt a null card  808 . This gave NAME 1  a final hand of three of a kind  810  and NAME 2  a final hand of only queen high  812 . As a result, NAME 1  has the best hand  814  with final Undo Count of two  816 . 
         [0091]    In all of these embodiments, if the actual player selects a card from the deck on the final round of the game that does not result in a winning hand for the actual player, then the round is automatically cancelled and the card dealt to each player on that round is removed from that player&#39;s hand. In this situation, the card dealt to the actual player need not be displayed as transferred to the actual player&#39;s hand, but is considered to temporarily form part of the actual player&#39;s hand until the automatic cancellation of the round is completed. Similarly, in this situation, the card dealt to each virtual player need not be shown being transferred to that virtual player&#39;s hand and is considered to temporarily form part of that virtual player&#39;s hand until the automatic cancellation of the round is completed. 
         [0092]    While particular embodiments of the present invention have been shown and described, it will be obvious to those skilled in the art that changes and modifications may be made without departing from this invention in its broader aspects and, therefore, any subsequent claims may encompass within their scope all changes and modifications that fall within the true spirit and scope of the invention.
