PROBLEM TO BE SOLVED: To intensely appeal the advantageousness of a sorting result for a player when a prize-winning ball is sorted as a ball possible to V-enter by judging a ball path along which the ball was guided so as to inform based on comparison of the number of prize-winning balls and the number of ejected balls. SOLUTION: A ball entering to a variable prize-winning ball device 20 is detected by prize-winning ball detectors 25a, 25b and a ball ejected from the device 20 is detected by ejected ball detectors 33a, 33b. The number of the prize-winning balls detected by the detectors 25a, 25b is compared with the number of the ejected balls detected by the detectors 33a and 33b, ball detection by a specific ball detector 48 is validated even in a normal state being a prize- winning standby state to starting prize-winning ports 4a to 4c so as to generate a specific game state under a condition that the specific ball detector detects a ball. Then, at the time point of the V-entry, information (big winning information) of the V-entry is noticed by sound or lamp.
