Knight's Tours

In a closed tour, the last move is back to the first square of the tour. Since the color of the square the knight was on changed each time it moved, and it ended on the same color square, it must have moved an even number of times.

The definition of a 'closed' knights tour on a m × n board, is a sequence of steps from a starting square a 1 to another square a m n, such that every square is visited exactly once, and the last sqaure is only one knight step away from a 1. Having said that, it is obvious, that for m n (mod2) = 1, there exists no closed tour.

Knight’s Tour Graph Representation Leading to a Symmetrical Planar Graph. The human solutions of the closed tour from Square 1 are probably more readily discovered from this symmetric representation than from any other approach. So too are the additional open tours starting from Square 1. 15.2 Full Knight’s Tour Solutions Open and Closed

Enumeration of 8×8 Knight's Tours

(a) Open Tours. Euler (1759) merely noted that the number of tours possible was very great. C. F. von Jaenisch (1862, vol.2, p.268) in attempting to quantify the matter argued that there are 168 knight's moves in the complete net of moves on the 8×8 board (42 in each of the 4 directions) and a open knight's tour uses 63 of these, so an upper bound on the number of open tours is the number of ...
