A gaming method of conducting a wagering game includes conducting one or more successive plays of the wagering game via one or more display devices in response to a triggering event. For each of the one or more successive plays, the method includes determining one or more award amounts based on the displayed outcomes of the one or more successive plays. The method further includes aggregating, via one or more processors, each of the one or more award amounts determined over the successive plays to calculate an aggregate award amount and determining, via at least one of the one or more processors, whether the aggregate award amount is greater than a threshold amount. The method includes providing an enhancement to the wagering game in response to the aggregate award amount being greater than the threshold amount.
