PROBLEM TO BE SOLVED: To solve the problem of difficulty to attract player's interest for a long time by a selection tendency of a variation pattern in a conventional pinball game machine.SOLUTION: In each of a special pattern selection table A and a special pattern selection table B, the correspondence between a variation pattern and a lottery value is determined such that a selection tendency of a variation pattern differs from a normal pattern selection table and a time-shortening pattern selection table. When shift conditions of probability variation are satisfied, specific game execution means completes executing a special game and then shifts to the probability variation in a mode where apparent determination on whether the shift to the probability variation has been performed is difficult. When predetermined changeover conditions are satisfied, variation pattern determination means changes a pattern selection table to be referred to within a restricted term after completion of execution of the special game or a small win game from the special pattern selection table to another special pattern selection table in change order corresponding to whether the shift to the probability variation has been performed. |
