PROBLEM TO BE SOLVED: To prevent interesting property from lowering when adopting a large-sized control device in a pinball game machine. SOLUTION: In a center accessory 6, a game ball entering in a ball entering port 40 passes through a warp gutter 46, outflows onto a stage 50 from a warp outlet 48, and is guided onto a freely movable surface 54. The game ball moves onto a dropping surface 56 side due to a slope of the freely movable surface 54, however, a retractable bodies 60 move up and down at this time, so that the path of the game ball is varied randomly due to contact with the retractable bodies 60. Consequently, the game ball flowing into the center accessory 6, that is, the central device 5 is made to randomly vary the path thereof and drops from the dropping surface 56 through a dropping notch 30a. The drop position differs depending on whether or not the game ball passes through the freely movable surface 54 after outflowing from the warp outlet 48 and also varyingly differs depending on contact condition with the retractable bodies 60 or without contact on the freely movable surface 54.
