PURPOSE: To improve visual excitement by displaying a demonstration image based on animation data having an indication to the effect that a varying prize ball device is at a disadvantageous position for a player during the generation of a right with a specified time as one unit on a varying display device repeatedly. CONSTITUTION: When a ball shot enters a specified ball receiving port 2, a variation display of three patterns is performed on a varying display device 50 and when the combination of patterns at the stoppage of the variation display gives a specified combination, a right is generated. At this point, a varying prize ball device 30 is driven by detecting the ball shot with an initial prize detector 28 to open an opening/closing plate 33, hence shifting to a first position advantageous for him. In this case, in the varying display device 50, the varying prize ball device 30 displays an indication to the effect that it is at the second position disadvantageous for a player by a demonstration image based on an animation data with a specified time as one unit during the generation of the right repeatedly thereby enhancing visual excitement. |
