Abstract
Slot machines having reels in which the symbol regions contain electroluminescent elements are disclosed. The electroluminescent elements define one or more reel symbols such as cherries, bars, a number '7', etc. In some embodiments, multiple electroluminescent elements are provided in each symbol region. This allows a given symbol to be displayed in multiple formats, with each format representing a different item. For example, a '7' could be displayed with its outline illuminated, with interior cross hatching illuminated, with a combination of the cross hatching and outline illuminated, or with different colors. The permutations can be increased if the symbol regions contains inked images in addition to the light elements. In such cases, when all light elements are turned off, the inked symbol appears.
