  • Publication number: 20140094240
    Abstract: Some embodiments include a two-dimensional poker game which includes a game board having a number of spaces for receiving game cards from one or more players. Game cards are placed on the game board such that they correspond in value or in suit with one or more previously placed game cards. Upon placing between one and five game cards on the game board to form a poker hand, a player receives a score. Scores established for particular poker hands may be modified if cards placed by the player cover a specially designated game board space. After each turn, a player adds the score earned for the current placed poker hand to any score from previous turns. At the end of the game, the value of any game cards remaining in a player's possession are deducted from the players cumulative score.
