Is it possible to move the knight from a1 to h8, visiting every square of the chessboard once?

	Select Click for Answer
No. A knight lands on light and dark squares alternately. If it begins on a dark square and makes 63 moves, then the last move must end on a light square. h8 is dark. Therefore the task is impossible.
