A gaming system for conducting a wagering game includes a display arrangement for displaying a video image overlaying a game display. The video image includes special symbols for indicating a bonus-award feature having a changing state. The changing state is continually updated or modified based on outcomes of the wagering game as displayed on the game display. The gaming system further includes a controller operative to cause the bonus-award feature to provide an award to the player in response to the state of the bonus-award feature meeting certain criteria.
