Abstract: A computer-implemented for reducing memory requirements for a user interface method includes generating, by one or more processors, a first matrix of symbols with columns that correspond to reels of cyclical symbols. The reels are configured to be rendered in adjacent sections of a display. The method further includes rotating, by one or more processors, each reel by a random amount responsive to receiving a spinning instruction. The method includes configuring a first reel to occupy both a first section of the display associated with the first reel and a second section of the display associated with an adjacent reel so that the adjacent reel will not be rendered when a pattern of symbols of the rendered reels is determined to correspond to a particular pattern. Data that represents the symbols of the reels is maintained in a shadow matrix stored in memory.
