Abstract
The invention provides a machine which simulates the game of snap. Two symbols representing the cards thrown by the two players are displayed at random from two groups of symbols. The snap call which is given when the two symbols displayed are the same is simulated by the player pressing a button. In the case of the player playing the machine the machine snap signal is controlled by a variable time delay circuit, and in the case of the player playing a second player the second players snap signal is controlled by the second player pressing a second button. The machine determines the first to call snap and effectively transfers cards to the winner. The machine may be provided with a prize or token dispenser, or may give free games in a coin controlled embodiment.
