PROBLEM TO BE SOLVED: To suppress passion for gambling into a moderate range in a slot machine with a stock function. SOLUTION: An RAM of a game control board is provided with a storage section 300 for the number of stocks. A first ward 301 stores the numbers of big bonus stocks and regular bonus stocks at present in one ward. A second ward 302 stores the upper limits of the number of big bonus prizes and regular bonus prizes to be stocked. The upper limit is set to a value determined based on a calculation so that a pay-out ball ratio, the ratio of the number of tokens paid out to the number of tokens charged, does not exceed a predetermined range. Even if the big bonus prize or the regular bonus prize is further generated, the further prize is not stocked, when the number of the stocks in the first ward 301 amounts to the upper limit of the second ward 302.
