Abstract

A game machine comprises hit flag counters which count up each hit request and count down upon the occurrence of each hit game. In these hit flag counters, if a hit cannot occur in spite of a hit request, the hit request is stored for the following games until the corresponding hit is obtained. A hit can be obtained only when the number of stored hit requests is not less than the number of inserted coins, so that the pay-out rate of the game machine is exactly controlled to be constant in totality.
