A control unit in communication with a plurality of gaming machines selects one or more of the active machines to be set to an enhanced play mode. The selection may be random or based on other factors. During the enhanced play mode, free games are provided, or the awards attributed to each symbol combination are increased, or additional symbols combinations are deemed winning combinations, or other game parameters may be changed that are advantageous to the player. The wagers by all the players playing machines connected to the progressive jackpot system are used to set the number of free games or the length of the enhanced play mode. The number of free games increases or the length of time of the enhanced play mode increases along with the jackpot that may be won in the enhanced play mode until the values are reset to starting values upon a jackpot win. This technique increases the likelihood that the jackpot will be won in the enhanced play mode as the jackpot progressively increases to optimize the attractiveness of the system to players.
