Figure 1: The Knight's Tour is usually played on a chessboard with counters to mark the progress. This tour starts on the square with the black knight and ends on the square with the white knight.
The Knight's Tour is an example of a classic mathematical problem that lends itself to easy and creative expression through computer programming. I created a Python program to help users practice solving the Knight's Tour. The Knight's Tour program is a good example of the simple yet powerful applications you can build with the Pygame Python library for computer gamers.
