PURPOSE: To make a driven ball flow in the lower part of the display part of an image display device so as to heighten a prize winning expectation by dividing an auxiliary game device into a first structural member and a second structural member, and temporarily rolling a driven ball rebounded on an obstacle nail to be guided to a designated prize winning port by a guide regulating part of the base of a recessed chamber of the first structural member. CONSTITUTION: A recessed chamber 30 is formed by a cylinder 24 in an opening 23 bored in the center of a unit base plate 22 as a first structural member of an auxiliary game device, the recessed chamber 30 is passed through an opening 2A of a game board 2, and the leading edge of the cylinder 24 is fitted from the back of the unit base plate 22. A guide regulating part 62 where a driven ball rebounded on an obstacle nail 61 or the like rolls temporarily is formed on the lower part of the leading edge of the cylinder 24, and passages 57A, 57B for forcing the entering ball to drop downward are formed thereon. When movable blades 51, 52 are put in the opening dotted line positions, the upper ends of the movable blades 51, 52 are largely stretched out over both side armor parts 26A, 26B to remarkably heighten the prize winning rate. The lower ends of the movable blades 51, 52 close dropping passage 57A, 57B to guide the ball to a central ball receiving chucker 50. |
