Description:
FIELD OF INVENTION 
   The invention relates to table games, specifically to card game tables, in particular to the tournament type game tables, e.g., for playing poker or a similar multiplayer games. 
   BACKGROUND TO THE INVENTION 
   Table games are known to be a part of many societies. Generally, these games can be classified into two groups: ones incorporating interaction of an individual with a dealer (such are the majority of the casino games, e.g., blackjack or roulette) and the others, hereinafter referred to as tournament games, where a participant, which can be an individual or a team, competes only with another participant or team. Another important feature of the tournament games as opposed to casino games is participation of a human factor such as visual interaction between the players, as well as their mathematical and psychological strategies. In this case, the strategy might have the same influence on the outcome of the game as the initial random combination of factors such as a card combination in the hand of each player. For example, a poker player can “bluff” by betting he/she has the best hand when in fact he/she does not and may win by bluffing if players holding superior hands will not call his bet. 
   Both mentioned types of the table games usually require the presence of a human operator, known as a dealer or croupier (hereinafter referred to as dealer). It should be noted that the role of such a dealer in casino games and tournament games is different. In the first case, a dealer may represent interests of the casino. For example, in a game of roulette the casino wins when the ball hits 0. In the second case, a random combination generator accomplishes the role of the dealer. In some game arrangements once in a game every player assumes the role of a dealer. Due to the requirement of the dealer having to maintain full control including supervising players, taking bets, determining the outcome of the game, calculating and paying winnings, collecting losses and all the while trying to be aware of any instances of cheating, the number of players per table has to be limited so as not to overtax the dealer. Accordingly, the overall profit of the casino or the club where the game takes place derived from the game is limited because the ratio between the dealer&#39;s salary and the income generated from the players is not high. 
   In all the table games described above, all actions, including players betting, game outcome determination, calculation of winners and losers and subsequent settlement, are conducted manually. This presents a number of problems. Firstly, mistakes can be made by the player in placing a bet, resulting in an invalid bet, while mistakes may be made by the dealer in determining winners and more particularly, in calculating and paying out wins. 
   Many attempts have been taken to automate the job of a dealer. One of the approaches is incorporation of the game machines, such as one disclosed in U.S. Pat. No. 6,695,695, issued in 2002 to Mark Angel. It discloses one of the variations of the electronic card game, in particular a variation of the game known as “video poker”. This video-implemented casino card game deals multiple hands. In a preferred embodiment it includes means for simulating a plurality of players on a game display. Each simulated player is dealt a hand of cards pursuant to a predetermined card game selected by a game player. Subsequent to the initial deal, the game player selects which hand to play. Once the hand has been selected, each hand is fully played. Only the game player&#39;s hand is fully revealed during play. Based on the game player&#39;s final cards, the player is paid according to a pay table. Thereafter, all hands are revealed and the game player is paid a bonus amount if the player&#39;s selected hand is the highest hand of the dealt hands. In a card game requiring a draw, or decision, unselected card hands are played according to a preprogrammed methodology within a gaming machine&#39;s internal microprocessor. Such a game replaces a dealer with a random (in reality—pseudo-random) sequence generator; however, being individual by nature it does not allow real interaction between the physical players and therefore cannot be used for the tournaments. All the participants of such a video game but one are simulated by a computer and all the psychological strategic parts of the game that constitute an important element of, i.e. poker, is eliminated since there is no human-to-human interaction. 
   U.S. Pat. No. 6,659,866, issued in 2003 to B. Frost et al. discloses an automated game table, in the preferred embodiment described as a table for roulette. In this apparatus, physical persons that participate in the game are provided with an electronic interface through which the players interact with a dealer. Such a table allows a multiple player arrangement, where the players place bets, and wins or losses are calculated using electronic means, while the game itself is conducted using traditional, manual systems operated by a dealer. The problem of such an arrangement is that despite the dealer need not watch for irregularities or calculate wins and losses, he/she still needs to physically conduct the game elements—for example, spinning a roulette wheel or tossing the cards. 
   Since the electronic table of the last-mentioned type incorporates a live dealer as an indispensable participant of the game, such table is inconvenient for use in multiple-table tournament games, e.g. poker, where there is no necessity to incorporate the actions of the dealer. More over, participation of several dealers (e.g., one per table) or of a common dealer for a plurality of tables, will impart additional complexity to the game and may lead to human errors. 
   OBJECTS AND SUMMARY OF THE INVENTION 
   It is an object of the present invention is to provide an electronic table for games with multiple participants without the presence of the dealer. Another object is to provide a tournament game table wherein the players play without participation of a dealer and where the players may visually and psychologically interact with each other. Still another object is to provide the electronic game table provided with means for combining a plurality of such tables into a multiple table tournament via Internet or a local area network without participation of a live dealer or dealers. Still another object is to provide the electronic table for the game of poker with a virtual dealer. 
   The electronic game table of the invention may comprise a standard game table, e.g., for poker, incorporating multiple player seats for tournament or side game play. Each player has a display device in front of him/her containing information about the card in pocket. The community cards are displayed in the center of the table on a display device. Each player has a console with control elements, such as buttons, computer mouse, touch screen, etc. for activating means of betting, such as coins, tokens, credit or smart card readers, etc. A function of a dealer is accomplished by a central server, e.g., a random combination generator. For participation in multi table tournaments, e.g., of a poker game, the aforementioned electronic game table is provided with means of interfacing with other tables participating in the tournament via Internet, Intranet, local area network, etc., without participation of a live dealer. In fact, the players that are present at the same table have a feeling or participation in an actual card game since they see each other and may use such moves of a card game as bluffing, psychological interaction, or advantageous use of mistakes made by other participants. In the case of a multiple-table tournament, the servers of the individual tables can be connected with an external CPU that may use, e.g., a master-slave protocol or any other type of data exchange. 
   DETAILED DESCRIPTION OF THE INVENTION 
   Although it is known that the proposed configuration can be used for different games such as dice, dominoes and miscellaneous card games, for the preferred embodiment we will describe an electronic tournament poker table. 
   It will be beneficial for clarification of the scope of the embodiment if we will provide a brief overview of the rules of poker. More detailed description can be found in the vol. 18 of Encyclopaedia Britannica (p. 108 of the 1966 edition). There are forms of poker suitable to any number of players, but in most forms the ideal number is six to ten players. Poker is almost always played with the standard fifty-two-card deck with cards of each of the four suits (clubs, spades, diamonds, hearts) ranking downward from the Ace to the Two (in some combinations Ace is the low card). In addition to these cards the Wild Cards or “freaks” are introduced into the deck in some versions of the game. These terms are used to denominate an additional card, which stands for any other card its holder wishes to name (i.e. Joker). The object of the game is to win the “pot” which is the aggregate of all bets made by all players in anyone deal. The pot may be won either by having the highest-ranking hand or by making a bet no other player calls. “Hands” are the combinations generally of five cards, its value being inverse proportion to its mathematical frequency; that is the more unusual the combination of the cards, the higher the hand ranks. Further on, there is the number of varieties of the game different by the rotation, betting procedure or betting limits.

   DESCRIPTION OF THE PREFERRED EMBODIMENT 
   An electronic card game table of the present invention is shown in  FIG. 1 , which is a three-dimensional view of the table. The electronic card game table, which hereinafter will be referred to as a game table is designated as a whole by reference numeral  10 . In its dimensions and shape the game table  10  corresponds to a conventional or standard card game table, e.g., the one installed in clubs or casinos for playing a poker game. In other words, the table  10  has a frame that may consist of a tabletop  10   a  and a supporting frame or base  10   b . The table top  10   a  may have horizontal or vertical orientation. For example, the game table  10  may have a horizontal tabletop and be designated for 6 to 10 players and may have the following dimensions: 82″×42″. 
   Although the minimum number of players may be 2 and the maximum number of players may be “n”, the embodiment of the game table  10  shown in  FIG. 1  is designed for  10  players. Each players sits in front of one of terminals  12   1 , . . . ,  12   10  so that they can observe all other players in order to have feel of a real game where they can bluff or use other psychological moves of a real game. Each player is provided with a player interface console  14   1 , . . . ,  14   10 . One of possible layouts of the player interface console is considered in more detail below. The game table  10  is equipped with a common display  16  of community cards and is located in a place clearly visible for all the players. For example, a common display  16  may be located in the center of the table (as shown in  FIG. 1 ) or on a remote hanging display panel (not shown). 
   The game table  10  is also provided with a table CPU  17  which is connected to all the player interface consoles  14   1 , . . . ,  14   10  and has means, such as a standard or wireless port  18  for connection to other remote CPU&#39;s that may be used, e.g., for the multi-table arrangement in the case of a tournament. To assure that the cards in every pocket and financial activities of the players are kept in privacy, player interfaces can be separated by partitions or hidden in recesses  22   1 , . . . ,  22   10 . 
   As shown in  FIG. 2 , each of the user terminals  12   1 , . . . ,  12   10  consists of a display  32 , a button  34  indicating a player assuming a role of a dealer in the current round (here we have to remind that the dealer role is absolutely virtual and is introduced only to assure the game flow, not to actually deal the cards), player in and out indicators  36  and  38 , bet operation buttons  40   1 ,  40   2 , and  40   3 , action buttons  41 - 1 , . . . ,  41 -n and means of payment (currency, credit or smart card reader)  43 . 
     FIG. 3  is a block diagram of the electronic units of the game table of the invention. As can be seen from this drawing, the CPU  17  contains random combination generator unit  19  which in the electronic table  10  of the invention plays a role of a principal dealer who is absent from the game as a physical person. In this connection it should be noted that not only the physical dealer but also a physical stack of card is also absent in the game. Therefore, whenever dealing the card is mentioned, it is assumed that appropriate card are seen on the screen of the appropriate displays. Each user terminal  12   1 , . . . ,  12   10  is linked to the common CPU  17  via respective links  13   1 ,  13   2 , . . . ,  13   10 . Furthermore, the CPU  17  is linked via a link  15   cpu  with the common display  16 . 
   As is known, there exists a number of varieties of the poker games different by the rotation, betting procedure or betting limits. Such varieties of the poker game are known as Seven Card Stud, Omaha Hi Lo, Texas Hold&#39;em, etc. The rules and strategy of these games are not beyond the scope of the present invention. In order to illustrate the use of the game table  10  of the present invention, let us assume that 4 players participate in a $2/$4 Seven Card Stud game. First, all the players have occupied their positions at appropriate consoles, e.g.,  121 ,  122 ,  124 ,  125 . The tournament begins when all the seats are occupied, and funds are deposited using the credit card reader  43 . According to the rule of poker, the deposits may be displayed to other players. This information can be shown either on the displays  32  or on the common display  16 , After this moment, none of the players can change the seat. In order to determine who deals the first round, each player is dealt one card randomly through the action of the random combination generator unit  19 . This is done by pushing on the appropriate action button, e.g., button  41 - 1 . Let us assume that the play who gets the lowest card. This fact is indicated by this player pushing the button  34  indicating the player assuming a role of a dealer in the current round. The cards are returned to the stack by pushing an appropriate action button, e.g., button  44 - 2 . The player who assumes a role of the dealer deals each player two cards face down and one face up, which can be done via the CPU  17  by pushing one of the action buttons. 
   Let us assume that all the players have anted $0.50. Betting is accomplished by pushing one of the bet operation buttons  40   1 ,  40   2 , or  40   3 . The player with the lowest up card makes a forced bet of either $1 half minimum bet or $2 full bet (player&#39;s choice) to start the game. The rest of the players, in clockwise order, either call the opening bet, raise it, using another bet operation button, or not call and “fold” their hands back to the dealer. All get a fourth card face up followed by a round of $2 betting. From this round on, the player with the highest up card(s) is always first to check or bet. 
   After the fifth card is dealt face up, the minimum bet goes to $4. The sixth card is dealt face up and there is another round of $4 betting. The seventh and last card is dealt face down and followed by the final round of $4 betting. All aforementioned operations, associated with pushes on any action or bet operation buttons at all the consoles are registered and stored in the CPU  17  via respective connection links  13   1 ,  13   2 , . . . ,  13   10 . The CPU  17  analyzes the players&#39; inputs and determines and awards the pot. 
     FIG. 4  illustrate an arrangement for a multi-table tournament in which several electronic game tables  110  and  112 , such as the table  10  ( FIG. 10 ) can be combined into a system in which CPU&#39;s  117  and  119  of individual tables are connected to each other and to a common multi-table display  116 . This can be done via standard or wireless port  18  ( FIGS. 1 and 4 ). 
   Thus, it has been shown that the present invention provides an electronic table for games with multiple participants without the presence of a common dealer, where the players may visually and psychologically interact with each other. The invention provides a table having a standard or wireless port for combining several tables into a system of a multi-table tournament. 
   Although the invention has been shown and described with reference to specific embodiments, it is understood that these embodiments should not be construed as limiting the areas of application of the invention and that any changes and modifications are possible, provided these changes and modifications do not depart from the scope of the attached patent claims. For example, the electronic game table of the invention may be designed for any number of participants that is equal or greater than 2. The table may have any shape, e.g., a circular or semicircular shape. The individual player terminals can be located on the bottoms of the hidden recesses made in the surface of the table top. The table is intended for a great variety of tournament games without limitation to the card games or to specific card games. For example the table can be used for playing dominoes, dice, etc. The outlet port of the table&#39;s CPU can be used for connection to a local area network or to Internet, Intranet, etc.
