A gaming system including a casino management server coupled to a plurality of gaming machines is described herein. The casino management server includes a processor programmed to initiate a bonus award feature, identify gaming machines associated with the bonus award feature, and determine a bonus award associated with the bonus award feature. The bonus award includes a first award value associated with a carded player account and a second award value associated with an un-carded anonymous player wagering session and/or account. The processor selects gaming machines having gaming sessions associated with un-carded anonymous players and displays a message notifying the player of the first award value associated with a carded player account and the second award value associated with an un-carded anonymous player. The processor also downloads the second award value to a corresponding gaming credit meter of each selected gaming machine associated with un-carded anonymous players.
