US Patent 9520029 Wagering game machine having enhanced eligibility for progressive jackpots

A gaming system includes game logic circuitry for a wagering game which awards one or more progressive jackpots upon the occurrence of a progressive jackpot triggering event. The game logic circuitry also operates the wagering game to grant progressive jackpot eligibility for one or more progressive jackpot awards for a player wagering an amount which would otherwise deny the player eligibility for the one or more of the progressive jackpot awards. As a result of maintaining progressive jackpot eligibility with the reduced wagering amount, one or more winning combinations in the pay table of the wagering game are removed or reduced.
