It is a puzzle game showing a grid of tiles; you tap a tile to flip 4 adjacent tiles; each tile when flipped reveals only a part of the bigger image, painted on the other side of the entire grid. The goal is to reveal the bigger image completely by flipping all tiles.The game has 5 difficulty levels, 1st level having 4 tiles, 2nd having 9 tiles, 3rd having 16 tiles, 4th having 25 tiles whereas 5th having 36 tiles. The quicker you are, the more you stand a chance to be at the top of the Leader-board.
