Abstract
The present invention provides an interactive, ongoing bonus game that operates at the same time as a base game of a gaming device and thereby enhances a player's award. The present invention provides one or more graduating multiplier or modifier displays, wherein the displays designate a position of value for each modifier. When certain symbols or combinations of symbols appear on the reels of the gaming device, the present invention modifies either the player's base game wager or a base game payout by the designated value of one of the modifiers. When certain other symbols or combinations of symbols appear on the reels of the gaming device, the present invention increases the designated value position for one or more of the modifiers.
