A method of operating the progressive jackpot system includes maintaining data in the progressive jackpot system controller representing a composite progressive jackpot pool comprising a predetermined base component, and an incremental component funded by a portion of wagers made at the gaming machines. A message is sent from the gaming machine to the progressive jackpot system controller in response to the occurrence of a triggering event on the gaming machine. The message indicates that the triggering event has occurred and includes data representing a desired proportion of the progressive jackpot pool to award to the player. The progressive jackpot system controller calculates a composite progressive jackpot award for the player based on the desired progressive jackpot proportion. The composite progressive jackpot award comprises a first component funded from the predetermined base component of the progressive jackpot poll, and a second component funded from the incremental component of the progressive jackpot pool. A message is sent from the progressive jackpot system controller to the gaming machine indicating the amount of the progressive jackpot award for the player. The progressive jackpot system controller replenishes the base component of the progressive jackpot pool to the predetermined amount. | 05-24-2012 |
