Slot machine
First Claim
1. A slot machine having a plurality of reels for sequentially displaying a plurality of series each comprised by a plurality of symbols, said slot machine comprising:
- random number generator means for generating a first random number and a second random number;
memory means for storing first judgment data and second judgment data, said first judgment data indicating a relation between said first random number and a group comprises of a plurality of predetermined combinations of symbols, said second judgment data indicating a relation between said second random number and a particular symbol combination included in said group;
judgment means for making a first judgment to determine said relation of said first random number by reference to said first judgment data, thereby to determine whether any combination from said group is to be displayed, and a second judgment to determine said relation of said second random number by reference to said second judgment data, thereby to determine which one of said combinations of said group is to be displayed; and
control means for controlling the stopped position of each of said reels such that said one of said combinations determined by said first and second judgments is displayed.

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.

11. A slot machine having a plurality of reels for sequentially displaying a plurality of series each comprises by a plurality of symbols, said slot machine comprising:
-
random number generator means for generating random numbers; memory means for storing first judgment data and second judgment data, said first judgment data indicating a relation between a random number which is taken from said random number generator means by a first trial and a group comprises by a plurality of predetermined combinations of symbols, thereby to determine whether any combination within said group can be displayed, said second judgment data indicating a relation between a random number which is taken from said random generator means by a second trial and particular combination, corresponding to the last-named random number, from said group which is to be displayed; judgment means for making a first judgment using said first judgment data to determine whether any combination of said group can be displayed and for making a second judgment using said second judgment data in order to select a specific combination from said group if said first judgment has determined that a said combination from said group can be displayed; and control means for controlling the stopped position of each of said reels such that said reels display said specific symbol combination. - View Dependent Claims (12, 13)
