WAGERING SYSTEM WITH IMPROVED EXPECTED VALUE DURING A SPECIAL EVENT

摘要

A method and system for conducting a wagering game with a changed expected value for a special event based on the achievement of a wagering-game enhancement parameter award. The wagering game includes a base game and a special event. The wagering game has a first expected value attributable to the base game and a second expected value attributable to the special event. The special event occurs in response to a triggering event. The first expected value attributable to the base game is decreased. The second expected value attributable to the special event is subsequently increased to compensate for decreasing the first expected value attributable to the base game.
