Abstract
A game of chance is conducted on a gaming machine controlled by a processor in response to a wager. A primary game outcome is randomly selected from a plurality of possible primary game outcomes. In response to the primary game outcome being a bonus triggering outcome, a plurality of secondary game outcomes are randomly selected and represented with respective successive free spins of a plurality of symbol-bearing reels. In each free spin the reels are rotated and stopped to place symbols on the reels in visual association with a symbol array. Payout multipliers are randomly selected for, and vary with, the respective secondary game outcomes. Payouts are awarded for the respective secondary game outcomes according to a pay table. Each payout is multiplied by the respective payout multiplier.
