Simulation of mechanical reels on a gaming machine
View Patent ↗A spinning reel slot machine has increased versatility, while having reels that are aesthetically similar to traditional mechanical reels. In one embodiment, the slot machine includes a plurality of optical fibers having first ends optically coupled to a surface of an image display device and seconds ends defining a curved display surface for displaying simulated mechanical reels to a player. In another embodiment, one or more of the mechanical reels has a transparent window at a location where a symbol would normally be present. A video display displays a video symbol in the transparent window. In yet a further embodiment, one of the plurality of mechanical reels has a miniature image display located at selected ones of the symbol regions for providing video symbols for the game. In yet further embodiments, a symbol region can produce more than one symbol in response to exposure at certain wavelengths or polarizations of light.
