Abstract

A gaming system including a cascading symbol game which utilizes a plurality of symbol display position matrices and a plurality of different directions of symbol movement. Each symbol display position matrix includes a plurality of symbol display positions. At least one of the symbol display position matrices includes one or more symbol display positions linked to or otherwise associated with one or more symbol display positions of at least another of the symbol display position matrices. If the gaming system determines that one or more symbols will be repositioned from one or more symbol display positions of one symbol display position matrix to one or more linked symbol display positions of another symbol display position matrix, the gaming system determines a direction of movement of such symbols.
