There are two types of tour, open and closed. In a closed tour the knight returns to it's original starting point. In an open tour it does not. In this version, you will earn more points for a closed tour than an open tour.

If you are unfamiliar with the rules of chess, you may press the 'Show Legal Moves' button to show all of your legal moves. There is no penalty for pressing this button.
