PROBLEM TO BE SOLVED: To carry out varied games by the combination of a plurality of pattern display devices and a plurality of variable prize-winning device. SOLUTION: When a main pattern display device 8 stops pattern variation after starting it as the result of entering of a ball to a starting prize-winning device 3 and the defined patterns are all winning patterns, the vane 31 of a first variable prize-winning device 4 is opened and closed. When the ball taken into the first variable prize-winning device 4 enters a specific prize winning part 25 while the vane 31 is opened, a sub pattern display device 9 stops pattern variation after starting it. When the stopped defined patterns are the winning patterns, the vane 11 of a second variable prize-winning device 5 is opened and closed. When the ball taken into the second variable prize-winning device 5 enters a specific prize winning part 13 while the vane 11 is opened, the rotator 6a of a third variable prize-winning device 6 is rotated. When the ball taken into the notch part 6b of the rotor 6a enters a specific prize winning part 6c, a big winning game is started where the opening and closing body 14 of a fourth variable prize-winning device 7 called an attacker or a big prize-winning port is opened and closed.
