PURPOSE:To improve the randomness by generating numerical information by a prescribed calculating expression at the time when a prescribed condition is formed, and determining beforehand the contents related to discriminating information at the time when a variable display device stops, based on the numerical, information at the time when a prescribed prior determination condition is formed, in a Japanese pinball game machine, etc. CONSTITUTION:When a game ball becomes prize-winning in a start port and one of detectors 34a-34c detects it, a fundamental circuit 61 fetches a value of a random counter in response to its detecting signal, and decides a great hit or a blank. This random counter becomes numerical information which becomes the base for a random number, and is used for determining an addition value to each picture pattern counter. The addition value determined in such a way is added successively to the picture pattern counter and the contents of the picture pattern counter are varied. Subsequently, the contents are determined by referring to this picture pattern counter at a stop picture pattern determination timing. According to this constitution, a random addition value added to the picture pattern counter is varied by a game state, therefore, the randomness is improved. |
