PROBLEM TO BE SOLVED: To effectively prevent the attack to a game machine by a tampered substrate, by comprising a means for updating a numerical value for generating a randam number value for judging a special game and a numerical value for generating a special game judgement value, and a means for determining a judgmenet value for special game. SOLUTION: The counters for generating the random numbers for judgement such as a random number for judging large prize used in the control of a game, are respectively updated (S10). The random numbers are respectively used for the judgement of large prize, the decision of failure figure, the judgement of specific figure, the judgement of REACH (to reach within an inch of winning), the decision of REACH motion, and the decision of large prize judgment value. Then the figure processings (S11, 12) are executed, whether the winning exists or not is judged (S13), and each counter for generating a random number for display is updated (S15). In this case the random number for deciding the large prize judgement value is also updated. Then the random number updating process for display is repeated until a set pulse is given from a periodical reset circuit (S17). |
