Abstract

PURPOSE: To easily uniform the game operation of each game base by providing a probability changing mechanism related to a hit detecting device so as to increase the operating probability of the hit detecting device in the set state of a winning probability enhancing circuit higher than that when the same circuit is not in the set state. CONSTITUTION: To an AND circuit 151 as probability changing means, the output of a motor stop timing detecting sensor 91 and the output of a hit latch circuit 106 are inputted, and its output is inputted to a hit detecting switch circuit 105 through an OR circuit 139. Thus, H-pulse is outputted from the hit detecting switch circuit 105 only by touching a Pachinko (Japanese pinball game) ball to a prescribed prize hole 26 while the hit latch circuit 106 outputs a signal H. According to this structure, although creation of prize probability increasing state is difficult, it can be easily continued if gained once, and the prize probability increasing state is surely performed for a prescribed time, so that the game operation of each game base can be easily uniformed by being hardly influenced by a mechanical difference.
