<P>PROBLEM TO BE SOLVED: To make a player feel a thrill such that the time when probability-variation ends is unpredictable, by performing a lottery for determining whether to continue or end the probability variation in a probability-variation state, thus enhancing the entertainment. <P>SOLUTION: A game board 1 is provided with a lottery starting device 16 having an inlet allowing a game ball to be flowed therein every time a prescribed number of variation display games in a probability-variation state is displayed. A specific game state lottery device 19 is provided which has a ball distributor 19c into which a game ball flows from the lottery starting device 16. A game ball flowed into the ball distributor 19c further flows into any of three passage holes 19e-19g. The specific game state lottery device 19 determines whether to continue or end the probability-variation state depending on a passage hole into which the game ball has flowed, among the passage holes 19e-19g. <P>COPYRIGHT: (C)2012,JPO&INPIT |
