Abstract
A gaming device employs a plurality of video displays, each presenting an output consisting of gaming symbols which are scrolled to simulate the effect of a revolving mechanical reel. The device includes electronic circuitry effectively storing, for each video display, an electronic signal sequence corresponding to a sequence of gaming symbols which is scrolled on the associated video display. Each electronic symbol sequence consists of a series of separate, sequentially-addressable sectors of electronic data storage, each sector containing a sequence of symbol addresses which access a single, common symbol signal storage space containing the symbols which occur in all of the presented sequences. A symbol sequence is scrolled by randomly selecting a starting symbol, sequentially addressing, from the starting symbol, the symbols defined by the symbol addresses in the reel for a predetermined period of time during which the reel rotates, and then halting the rotation at a stopping symbol. The scrolling effect is enhanced by presenting the output of each video display at a common frame rate and changing the location of a displayed symbol by a predetermined amount each frame.
