PROBLEM TO BE SOLVED: To improve game amusement by a first pattern and a second pattern. SOLUTION: Every time a start winning ball detection switch 3 outputs to a controller 5 the detection signal of a ball 2 which enters a start winning port device 1, the controller 5 lights one of the light emission display devices 12 of an indicator 11. When the number of the turned-on light emission display devices 12 becomes a prescribed number or larger, the controller 5 variably displays the first pattern 7 at a first pattern display device 6. The controller 5 variably displays the second pattern 9 at a second pattern display device 8 by the form of the stopped first pattern 7 and at the point of time of stopping the first pattern 7 as a variation start trigger. When the stopped second pattern 9 is a large winning pattern preset in the controller 5, the controller 5 starts the opening/closing operation of a variation winning port device 13. |
