PROBLEM TO BE SOLVED: To minimize disadvantage imposed on a game player by constituting so as to enhance game value imparted to the game player when exceeding a prescribed value in a counting value of an invalidity counting means to count materialization of a variation starting condition generated after going over the storage upper limit of the starting storage part. SOLUTION: When a starting hole sensor 17 is turned on after a shooting ball enters a starting winning hole, whether or not the starting winning storage number reaches a starting storage upper limit value is judged in a basic circuit 53, and when it is judged as NO, the starting winning storage number is increased by one to extract a big hit judging random number value. This random number value is stored in a storage area arranged in response to the respective starting winning storage numbers (n). While, when the starting winning storage number reaches an upper limit value, a value of an invalidity counter is increased by one, but when a value of this invalidity counter exceeds a prescribed value, the value of the invalidity counter is cleared, and an invalidity upper limit flag is set. When a big hit is made at this time, the big hit is set as an advantageous reliably changeable big hit. |
