The following knight's tour is on a 120x120 chessboard, which has 14,400 squares. Therefore it would take a knight 14,400 moves to complete the circuit, which would take 4 hours to perform in the real world at one move per second with a real chess piece, assuming you don't make any mistakes. Oh, and if each square is 1 inch by 1 inch, the board would be 10 feet on a side.
