PINBALL GAME MACHINE
Document Type and Number:
Japanese Patent JP3172209
Kind Code:
B2
Abstract:
PURPOSE: To improve an interest by fluctuating probability that a display at the time of stop of a variable display device becomes specific discriminating information, so as to become a right generation state, when a hit ball goes into a first variable prize-winning ball device, in a Japanese pinball game machine, etc.,
CONSTITUTION: Before a variable display device 5 stops, probability that discriminating information at the time of stop becomes specific discriminating information is determined by a probability fluctuation control means. That is, whenever a game control program is executed once, counting is executed at random, and from a result of its counting, a left picture pattern display part 31a, a middle picture pattern display part 31b, and a right picture pattern display part 31c are subjected to display control. In accordance with this probability, the discriminating information at the time of stop of the variable display device 5 becomes the specific discriminating information. Also, in this case, when a hit ball goes into a first variable prize-winning ball device 8, it becomes a right generation state.
