A slot machine is described which allows a player to participate in an additional game of chance whenever a winning combination of symbols includes a special bonus multiplier symbol. In such instances, the award for the winning combination is multiplied by a randomly determined value, thereby increasing the attractiveness of the game. In the preferred embodiment, the bonus multiplier is selected using a weighted random number generator.
