Play the classic Knight’s Tour challenge on your iPhone. Using only the knight’s standard L-shaped moves, the basic challenge is to land on all 64 squares, visiting each square only once.

If you can master that, there are two more challenges. In level 2, the 64th square on which you land must be one knight’s move from your starting point. In level 3, you must go from the designated starting square, and end on the designated ending square on the 64th move. Try with TestiPhone
