PROBLEM TO BE SOLVED: To provide a structure for carrying out performance by rolling of a game ball without lowering the moving speed of the game ball accepted into a rolling part. SOLUTION: The accepted game ball draws a loop-like track guided by third circular guiding parts 73a and 73b, a fourth guiding part 74 and a fifth guiding part 75, so that lowering of the initial speed of the game ball is suppressed. The decelerated game ball rolls into a specific rolling part 76 in the center and rolls with lowering of its rolling speed suppressed by a first circular guiding path 71, to be guided to an ejection port 761. The game ball placed on a second guiding path 72 positioned in the specific rolling part 76 is ejected through a route for entering a starting prize-winning port most easily.
