# Knight's Tour

How can your knight help you during a game if it's not truly acquainted with the chessboard? Make sure you give your knight a tour around the chessboard, so it gets to know the whole battlefield before you start another game.

Here's what you need to know about the knight's tour:

## What Is The Knight's Tour?

The knight's tour is a chess problem that first appeared in around the ninth century. It consists of a knight starting at any square of the board and moving to the remaining 63 squares without ever jumping to the same square more than once.

There are two kinds of solutions to the knight's tour problem, the closed and the open tours.

## Closed Knight's Tours

Closed knight's tours are those in which the knight's last move is one knight's move away from the initial position. In practice, this means that the knight's path forms a loop. In this type of tour, the knight can always go through the same path, wherever its starting square is.

There are 26,534,728,821,064 possible closed tours (including reversals, reflections, and rotations). One famous closed tour is the one used by the Turk, a fake chess automaton created in 1770.

## Open Knight's Tours

Open knight's tours are those in which the knight can't reach its starting square from its final position. The knight can't go through the same path when placed on different starting positions in this type of tour.

A well-known open tour was created in 1847 by William Beverley and published in The Philosophical Magazine in 1848. Beverley's solution is famous for combining the knight's tour features with those of the mathematical concept of a magic square. Assigning a value to each square (determined by the knight's move order) and adding the numbers on each column and each row together always result in 260.
