Abstract
For each bet on a slot machine game, such as a conventional reel-type game, a fraction of a free game is stored in the machine's memory, where the stored free game fraction is associated with the amount bet. Thus, each possible bet amount option is associated with a particular free game pot in memory. Each paid-for play may accumulate any free game fraction, such as 1/10, ⅕, ¼, ⅓, etc. The player is notified of the accumulated free games on a video screen so the player wants to keep playing so as to not waste any stored free game fractions. The player may play stored whole free games at any time by actuating a button. The free game pots may be easily added to existing games without significant regulatory involvement and does not affect the casino's profit.
