Abstract

See full text

An amusement device and method of operation are disclosed wherein a plurality of payout schedules which govern the conduct of the game are retained in a memory. The actual payout rate of the apparatus is constantly determined and the actual payout is compared with predetermined limits. If the actual payout exceeds the limit, the apparatus automatically selects another payout schedule which alters the probability of a player's winning. The game is fair because the payout schedule governing conduct of the game is displayed to the player.
