Abstract
A method for operating a microprocessor controlled, reel type slot machine in which payoff is determined before a final game outcome is displayed to a player. A pre-defined count of random numbers is generated and presented to a digital filter having tap outputs which correspond to paytable payline equations. The minimum number of payline equations is equal to the number of distinct paylines in the paytable plus one. Any changes in game outcome are taken into account by modifying variables in computer memory and as such do not require a change in tables stored in computer memory. Several features for attracting players to the apparatus and increasing the enjoyment of playing a game are included.
