This is a puzzle game which challenges your memory. Two grids are composed of m shapes (rows) and n colors (columns). The bottom one is for play and the top one is for hint. You must touch the cells of the bottom grid and turn them face up one by one. The next cell touched must match shape or color with the previous cell touched. If so, you can touch another cell. If not, the unmatched cells will be turnt face down and you touch over again.
