PROBLEM TO BE SOLVED: To improve a taste by providing a possibility that a game ball flowing out of a stage returns to the stage again. SOLUTION: This center roll object 9 is provided with the stage 11 and a sub-stage 12. The stage 11 is formed with a guide hole part 14 with a high win probability. The sub-stage 12 positioned in the front side of the stage 11 is provided with a central rotating roll object 16 and side rotating roll objects 17 and 17 to be rotatingly driven. The central rotating roll object 16 is so constituted as to embed a magnet 16b in a circular rotor 16a and, when the game ball 5 is attracted to the magnet 16b, it is made to return to the stage 11. The side rotating roll object 17 is so constituted as to form circular recessed retaining parts 17b in two parts around the circumference of the rotor 17a. When the game ball 5 is retained to the retaining part 17b, it is highly possibly returned to the stage 11. COPYRIGHT: (C)2005,JPO&NCIPI
