An apparatus and method for a secondary game of a wagering gaming system, and particularly the increase of an award in the secondary game by the value of different multipliers associated with different amounts wagered in a primary game. A secondary game provides a total award to a player based on the multiplier associated with the wagered amount in the primary game by applying the multiplier to the amount of the award earned by the player in the secondary game. A particular wagerable amount may be associated with a multiplier that is predetermined, or randomly selected from a group of predefined multipliers, or selected from a group based on a probability. The range of possible combinations of wagerable amounts and multipliers are displayed to the player in the base game to provide an incentive to maximize the wager.
