<P>PROBLEM TO BE SOLVED: To solve the problem that a conventional pinball game machine has been difficult to attract the player's interest for a long time using the tendency of selection of variation patterns. <P>SOLUTION: In each of a special pattern selection table A and a special pattern selection table B, corresponding relationship is defined between a variation pattern and a lottery value so that the tendency of selection of variation patterns is different from that of a normal pattern selection table or time-reduced pattern selection table. When a condition of shift to a winning probability increasing status is satisfied, a specific game performance unit shifts a game to a status in which it is difficult in appearance to determine whether the game is shifted to the winning probability increasing status after the end of performance of a special game. When a predetermined switching condition is satisfied, a variation pattern deciding unit switches the pattern selection table to be referred in a limited time period after the end of a special game or small prize game, to another special pattern selection tables in a switching order according to whether the game is shifted to the winning probability increasing status or not. <P>COPYRIGHT: (C)2013,JPO&INPIT |
