PROBLEM TO BE SOLVED: To improve amusement by comparing the number of balls to enter a big prize winning port (prize-winning balls number) with the number of balls to be discharged from the big prize winning port (the number of discharged balls) and executing various kinds of announcing operations or game operations based on the comparison result. SOLUTION: A game control circuit substrate 50 inputs the detecting signals of a specified ball detector 48, start ball detectors 5a-5c, remaining ball detectors 33a and 33b and prize winning ball detectors 25a and 25b or the like. Then solenoids 25a and 25b are driven by detecting the prize winning of the shot ball to a start prize winning area and a variable prize winning ball device is shifted to a first state which is advantageous for a game player. Besides, it is shifted to the more advantageous specified state by detecting the prize winning of the shot ball to the specified prize winning area of the device. In this case, the balls which win the prize in the variable prize winning ball device and the balls discharged from the device are respectively detected. If the number of the prize winning balls does not coincide with the number of discharged balls when a prescribed period elapses after the device becomes the first state, a peculiar effect sound is outputted from a speaker 62.
