Overlap Elimination is an interesting puzzle game. The objective is moving the pieces to make the same shape showing on board. The rule is: When even number pieces are overlapping, the overlapped part will be eliminated and display background(Black + Black = White). In Tricolor mode, when two different color pieces are overlapping the overlapped part will show another color(Red + Green = Blue). Player can make the shape at any place on the board. Player also can overlap on the original shape. Feature:Eight Packages, 920 Levels.Big Play Area, Cover Mode.Six Themes
