PROBLEM TO BE SOLVED: To solve the problems of lack of change and fun because a jump-in ball which jumps into a jump-in chamber makes a monotonous movement. SOLUTION: The guide path (14) of the jump-in ball is provided inside the jump-in chamber (1) provided with turning blade pierces (4) on the left and right of an opening part (3), a first drop port (15) to be opened and closed by an opening/closing plate (17) is formed in the middle and a second drop port (16) is formed at the back respectively. A winning jump-in ball is selectively dropped to the first or second drop port (15, 16) by the opening/closing movement of the opening/closing plate (17), a flow is changed inside the jump-in chamber and it is made to enter one of plural winning ports provided on the downstream. |
