Slot machine with random number generation
First Claim
1. A slot machine of the type having plural series of moving symbols juxtaposed to each other, each of said plural series of symbols comprising a plurality of moving symbols arranged in an array and in which a predetermined number of coins is ejected when combinations of symbols on prize-winning lines on said array coincide with predetermined prize-winning combinations, said slot machine comprising:
- random number generator means for generating a plurality of random numbers within a predetermined range;
sampling means for selecting one random number out of said plurality of random numbers generated by said generator means;
a winning probability table for storing a relationship between a group and said random numbers, the group being one of a plurality of groups made up by classifying prize-winning combinations;
judgment means including means for judging whether the value of said random number corresponds to any of said numerical values representing said groups said judgment means also including means to judge whether a win can be awarded or not and, in the affirmative, further including means for judging to which of said groups said random number belongs, by referring to said winning probability table;
hit request signal generator means for generating a hit request signal upon judgment of a win by said judgment means, said signal requesting the machine to stop said moving symbols so as to display one of a particular group of prize-winning combinations in the group judged by said judgment means; and
control means responsive to said hit request signal for so stopping said symbols.

Abstract
A slot machine is provided which has a winning probability table for storing a relation between a group and random numbers, the group being one of a plurality of groups made up by classifying prize-winning symbol combinations. The range of random numbers is properly fixed so that the winning probability is determined. Prior to the start of a game, one of the random numbers is sampled from a plurality of random numbers. The decisions on whether there is a win or not, and on which group the sampled random number belongs to if there is a win, are made with reference to the winning probability table. A hit request signal is generated for the latter decision. The hits are of different sizes, that is to say that different hits pay different numbers of wins. The larger the hit, the fewer random numbers correspond to it. The stopping series of symbols is controlled in accordance with the hit request signal.
