The coin operated games machine has three discs with symbols or numbers that are rotated and stopped in a pseudorandom cycle controlled by a microprocessor based system. The numbers finally displayed are compared with combinations that provide winning outcomes. The housing has two risk displays (15) that indicate a range of values and can be selected by the player with the aid of push button selectors (17). A jackpot game facility (19) is set in the centre of the housing panel and has illuminated strip displays (20,22). The centre unit indicates the level of the jackpot and the others the risk level. Selection of the game is under control of the player using push buttons (7).
