A method of playing an interactive, computerized, multi-player card game in which desired cards are selected by players, some of which may be virtual players generated by the game’s software. Each real player uses a computer or similar device that is connected to a network. Virtual player card selection and betting is controlled by computer software. After each player has selected a card in a round, computer software determines what card each player is dealt. Null cards having no value in the scoring are dealt when there is a conflict in card selection or when a player fails to select a card within a time limit. The games follow the rules of poker.
