Abstract: The present invention relates to a system for operating a bingo game. Play cells are organized into a pair of linked M×N grids, where each one of M and N is greater than two. Each one of the play cells bears one of a predetermined set of symbols. At least some of the symbols are selected by a means for randomly selecting different symbols from the set. The symbol selection designates the play cells to be daubed. A predetermined pattern spanning two grids is displayed by a means for displaying the pattern. The pattern is to be formed by combining different sub-patterns formed within each of the linked grids using the daubed play cells.
