PROBLEM TO BE SOLVED: To provide a game machine suppressing a start winning rate even if increasing the number of game balls flowing in a guide passage and capable of giving a player expectation to the start winning. SOLUTION: This game machine is formed with four grooves in the outer circumferential face of a sorting roller 410, applied with a driving force by a motor 420, and changed over between a connected state of a stage to a special hole in the inner side of the sorting roller 410 and an unconnected state by the grooves. This constitution can change the rate of the ball guided to the special hole in correspondence to the state of the sorting roller 410 and change the winning probability (start winning rate) of the game ball to a big winning hole 33 positioned in its lower side according to the lapse of the time. As a result, this game machine can produce a state of a low start winning rate and suppress the start winning rate while increasing the number of game balls flowing in the guide passage.
