PROBLEM TO BE SOLVED: To solve a problem with a conventional pinball game machine in which it is difficult to attract a player's interest for a long period by use of a selection tendency of a variation pattern.SOLUTION: In each of a special pattern selection table A and a special pattern selection table B, a correspondence between the variation pattern and lottery value is determined so that the selection tendency of the variation pattern is different from that in a general pattern selection table or a time-reduced pattern selection table. When a shifting condition to probability variation is satisfied, a specific game execution means shifts a special game, after the completion of execution thereof, to probability variation in a mode such that the shifting to probability variation is difficult to apparently discriminate. When a predetermined switching condition is satisfied, a variation pattern determination means switches the pattern selection table to be referred, within a limitative period after the completion of execution of the special game or a minor jackpot game, to another special pattern selection table, in a switching order according to whether the shifting to probability variation is performed or not. |
