Abstract
A slot machine is provided in which the symbols or indicia to be displayed are selected by using a random number generating technique to generate a random number for each display position, the random number being selected from a range of numbers corresponding to the number of possible indicia for that position with each number corresponding uniquely to one of the indicia. A two step random number selection technique is used wherein the first step comprises selecting one of a plurality of sub-ranges of said range of numbers, one of the sub-ranges being the full range of numbers, and the second step comprises randomly selecting a number from the selected sub-range of numbers and displaying the corresponding indicia.
