The game machine includes: a first operation button corresponding to a first operation performance; and a second operation button corresponding to a second operation performance. An operation performance wherein an appearance rate of each unit performance period is low out of the first operation performance and the second operation performance, has high in-special-processing-execution reliability which is probability that a profit state occurs when special processing is executed. The operation performance wherein the appearance rate of the each unit performance period is low, has the higher in-operation-detection execution probability as profit capable of being obtained by the player is larger out of a plurality of kinds of profit states. <P>COPYRIGHT: (C)2013,JPO&INPIT |
