<p><P>PROBLEM TO BE SOLVED: To avoid a situation in which a game must be stopped in an advantageous game state such as a probability variation state in a game machine. <P>SOLUTION: When a mode changing switch 39 is turned on (S1:Yes), the probability of determination is increased by a mode changing process (S4) if the game state is the probability variation state or a time shortening state, and the variation time is shortened so that a jackpot can be easily made. If a jackpot is made, termination of the probability variation state and the time shortening state is quickened. Accordingly, the probability of termination of the advantageous state is high even if the game state is the probability variation state or the time shortening state just before the closing time in a game parlor, so that a player can play the game at ease. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
