PROBLEM TO BE SOLVED: To solve the problem that it is difficult to draw player's interest over a long period of time using the selection tendency of a variation pattern in the case of a conventional pinball game machine. SOLUTION: In each of a special pattern selection table A and a special pattern selection table B, the correspondence relationship between variation patterns and drawing values is determined so that the selection tendency of the variation pattern is different between a normal pattern selection table and a time shortening pattern selection table. When the shifting condition of probability variation is satisfied, a specified game execution means shifts to the probability variation in such a form that it becomes difficult to distinguish on appearance whether or not shifting to the probability variation has been executed after the end of execution of a special game. When a predetermined switching condition is satisfied, a variation pattern determination means switches a pattern selection table to be referred to within a limited period after the end of execution of the special game or a small winning game from the special pattern selection table to the other special pattern selection table in a switching order according to whether or not the shifting to the probability variation has been executed.
