Abstract
An electronic amusement device is provided in which a set of symbols is displayed on a cathode ray tube. A set of winning symbols is also displayed in response to selection by a player. Upon actuation of a lever arm by the player, the first-mentioned set of symbols is randomized and the resulting display is compared with the selected winning symbols. A reward output is provided in response to match of one or more of the randomized symbols with the selected winning symbols.
