Abstract: To provide a novel game machine.SOLUTION: A game machine achieves state shift without discomfort even in an irregular time, by considering information related to storage (reservation information) in addition to a game state of a main control unit. In particular, in reception of an opening command of small winning or an opening command of jackpot with winning having no time-shortening in a time shortening state, a subsequent expansion is branched according to whether there is storage of a second special pattern. In more detail, when there is storage of the second special pattern, a big role performance of a repeated events continuation is executed, and a mode is shifted to a drive mode (repeated events state mode). On the other hand, when there is no storage of the second special pattern, the big role performance of the repeated events finish is executed, and a mode is shifted to an animal mode (repeated events finish mode). By employing such a control content, a mode (stage) can be shifted by considering not only a game state of a main control unit, but also the number of storage, and a special repeated events mode can be reported to a user in a manner of capable of being easily understood.SELECTED DRAWING: Figure 61
