<P>PROBLEM TO BE SOLVED: To provide a game machine which enables a player to keep a desire to play without feeling bored even when the same game state continues. Ž<P>SOLUTION: In a non-time-shortening game state, the variation time of normal patterns is controlled to the first time. When a jackpot pattern with time shortening is determined by the drawing of a jackpot and a time shortening game state is attained after the end of a jackpot game, the variation time of the normal patterns is controlled to the second time made shorter than the first time. The time shortening game state is ended usually when the variable display of special patterns is performed 50 times at maximum. Also, when a time shortening premium pattern is determined by the drawing of the jackpot, a time shortening premium opportunity is set. In the time shortening premium opportunity, when the jackpot pattern with time shortening is determined by the drawing of the jackpot, the time shortening game state generated after the end of the jackpot game continues until the variable display of the special patterns is performed 100 times at maximum. The setting frequency of the time shortening premium opportunity is higher in a low probability game state than in a high probability game state. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
