<P>PROBLEM TO BE SOLVED: To solve the problem that when the duration of winning probability oscillation is limited, the probability of jackpot generation is reduced as the remaining time of the duration is reduced, and the expectation of a player is also reduced. <P>SOLUTION: A Pachinko game machine 10 includes a specific game executing unit 122, a previous information notification unit 157, and a presentation determining unit 132. The specific game executing unit 122 shifts a normal game after the end of a special game to a winning probability oscillation state, and terminates the winning probability oscillation state when a following jackpot is not generated during a predetermined period. When a game ball enters a start pocket, the previous information notification unit 157 notifies the presentation determining unit 132 of a lottery result of the entrance of the game ball, regardless of whether corresponding symbol variation display is immediately started or not. The presentation determining unit 132 refers to a larger number of lottery results as the remaining time of the winning probability oscillation state is reduced, from lottery results reported from the previous information notification unit 157, and displays presentation for indicating a lottery result within the range of reference, as presentation during the winning probability oscillation state. <P>COPYRIGHT: (C)2012,JPO&INPIT |
