<P>PROBLEM TO BE SOLVED: To provide a Pachinko machine that has no provability that the number of prize balls to be gained by the player is too large or too small depending on the type of a jackpot during a jackpot game. <P>SOLUTION: When a first state occurs in which the probability of hitting a next jackpot is higher than normal for a certain period of time after hitting a jackpot, a second variable prize-winning device 25 operates to execute 16 rounds in the round of opening/closing of a second big winning hole 25a, causing balls to enter the second big winning hole 25a during a jackpot game and the total p1 prize balls to be released. When a second such a state occurs, two rounds are executed, causing total p2 prize balls to be released. Since the release of prize balls is set to satisfy formula 0.125≤r<1, wherein p2/p1=r, there is no probability that the number of prize balls to be gained by the player during a jackpot game is too large or too small. <P>COPYRIGHT: (C)2012,JPO&INPIT |
