  • Patent number: 5413353
    Abstract: A method of playing a blackjack type of card game in which the players play against one another rather than against a dealer. Initially, each player places an identical wager to form a pot and then receives two cards face down from a dealer. The dealer receives no cards but the house collects a rake from each pot. A player may split pairs, draw additional cards or stand. A player receiving a blackjack on the first two cards (i.e., ace and ten value card) or scoring the highest card sum without exceeding 21 wins the pot. If two or more players receive a blackjack on the first two cards, all tie, and the game is repeated using the same pot. If two or more players achieve the same card sum, then a predetermined schedule may be used to ascertain that all tie, and the game is repeated using the same pot.
