Make up two mosaic pictures from rectangular two-sided tiles, rotate tiles, turn them upside down and change over any two tiles. Assemble both pictures separately or mix their tiles to make a task more difficult.
To make things even more difficult, you can choose the mode when you see only the active tile and the tiles already solved. You set the tile's size, shape and quantity up to 1,600. The game can be saved.
