Abstract: A gaming machine includes a gaming cabinet, an electronic display device, a masked area, a light source, and a diffused lighting area. The display device is within a cabinet enclosure and has an active area with an image surface, which is defined by a plurality of active edges and is configured to display images of a casino wagering game. The masked area is adjacent to the active area and lacks any display of the images of the casino wagering game. The light source is concealed from view relative to a player position and emits an initial light. The diffused lighting area is adjacent to the masked area, extends to overlap the adjacent peripheral edge of the cabinet enclosure, and includes a single diffuser that receives the initial light and transmits it towards the player.
