Abstract
A slot machine having X series of symbols arranged side by side which selects a combination of symbols on a winning line. For the selection of a combination of symbols, a random number is sampled from a series of random numbers the number of which is 2.sup.n and is referred to symbol tables associated with each symbol series wherein are coded data on symbols of which the number is equal to the Xth root of 2.sup.n. A combination of symbols is thus selected with the same probability as for sampling a random number.
