Abstract
A reel mapping scheme which allows one standard reel stop control software routine to control the stopping of the reels when the device is operated as a standard gaming device, a multiple stop gaming device or a virtual reel gaming device. The gaming device includes a number of rotating symbol bearing reels, each reel having n stop positions associated with each symbol on the reel. For each reel, the gaming device stores a map of the symbols on the reel in a symbol map memory and a map of the stop positions on the reel in a stop map memory where the data stored in the first location in the reel map memory represents the first stop for a symbol whose data is stored in the first location in the symbol map memory. Three mapping indexes are stored for each reel. One index stores only one value representing an address offset to the reel map memory at one location for each symbol on the reel to provide a standard gaming device. A second index stores two or more reel map address offset values for each symbol on a reel to provide a multiple stop gaming device. A third index stores, for each of a number of symbols on a reel, the same reel map address offset value at different locations in t…
