Abstract
A slot machine has a memory in which first judgment data and second judgment data are stored. These first judgment data show for any first random number, whether any one of a group of prize-winning symbols can be selected, and the second judgment data show, for any second random number, the particular prize-winning combination to be displayed. A judgment is thus performed twice, using random numbers sequentially sampled from a random number generator, using the first and second data. According to the result of these two judgments, the stopped position of each reel is controlled such that the symbol combination of this specific winning combination will be displayed.
