<p>PROBLEM TO BE SOLVED: To prevent a fraud.SOLUTION: When a system is reset, a count value of a free-run counter is stored in a prescribed variable security time register provided in a game control microcomputer. In an initial setup, an extention time when extending a security time is randomly set by using a storage value of the variable security time register or the like. The free-run counter is, for example, backed up by using a backup part in a main board such as a backup area in RAM of the game control microcomputer, and a common backup power supply. After the operation state of the game control microcomputer is transferred from a security mode to a user mode, when a setup by a random number circuit setup processing is completed, a random number generation operation is started. A lapse time in a special symbol game is measured by a common timer.</p> |
