Initially resembling "15", the slidder puzzle, SWIZZLE takes the idea much further. Tiles dont just slide, they flip in rows, columns AND diagonals, revealing the numbered reverse of the tiles, and with Diagonal flipping, tiles can lie sideways and even upside down.

Starting with the beginner 2x2 grid, numbered 1-4 on the front, and 5-8 on the reverse, the tiles are flipped automatically making the challenge to return the tiles to the original numerical order in the lease number of moves.

Each Puzzle can be individually selected using simple spin controls and the best score (lowest moves to complete) are recorded and displayed for each.

As you improve, and learn new techniques, you can return and replay any puzzle again and again to try to improve your score.
