PROBLEM TO BE SOLVED: To generate game values a plurality of times with one game ball entering a prize device. SOLUTION: Game balls entering a starter prize device 9 are guided to guide pieces 22a and 22b and pass through a hole part 24a formed in a detection switch 24. Thereafter, the game balls move through a rolling path made of a circular arc-shaped guide piece 22c and a cylinder member 23. When the game balls reach near the upper most part of the rolling path, for example, a tapered part 27 formed at an upper part of the cylinder member 23, they are guided in the direction of the detection switch 24 and pass through the detection switch 24 again. This allows the generation of game values, namely, variable actions of a variable display device, at the frequency equivalent to the frequency at which the game balls pass through the detection switch 24.
