Abstract
The present invention expands a wildcard symbol into one or more symbol positions of the symbol matrix if two or more wildcard symbols appear in the symbol matrix in a predetermined configuration relative to one another. In a preferred embodiment of the present invention, two or more wildcard symbols appearing in adjacent positions of the same row of a symbol matrix expand into all symbol positions of the columns in which the adjacent wildcard symbols appear.
