A gaming machine for conducting a wagering game includes a game display. A transmissive display is positioned in front of the game display directly in the player's line of sight including game-play regions at which symbols appear and regions above, below, between, and to the sides the game-play regions. The transmissive display is operable to selectively display transparent, translucent and opaque video images over the game display. The transparent, translucent and opaque video images may be used to change, for example, a play mechanic associated with the wagering game and any reel symbols associated with wagering game. The transmissive display may also be used to provide interactive player control and player selection elements for the wagering game and to facilitate player inputs to the gaming machine. The transmissive display may be further used to provide bonus features associated with a bonus game played at the gaming machine.
