Preparing the Chessboard...
The Knight's Tour is a sequence of moves of a knight on a chessboard such that the knight visits every square exactly once. It's a fascinating problem in mathematics and computer science dating back to the 9th century.
1. Select a starting position by clicking any square on the board.
2. Move the knight to any highlighted square (valid "L" shaped moves).
3. Try to cover the entire board without revisiting any squares.
4. Use the Undo button to backtrack if you make a mistake.
5. Complete the tour by visiting all squares exactly once!
Move the knight chess piece to every square on the board exactly once. The knight moves in an "L" shape: two squares in one direction and then one square perpendicular, or one square in one direction and then two squares perpendicular.
1. Start: Click any square to place the knight and begin the game.
2. Move: Click any highlighted square to move the knight there.
3. Strategy: Plan your moves to cover the entire board without getting stuck.
4. Undo: Made a mistake? Use the Undo button to go back one move.
5. Reset: Start over with the Reset button.
- Start near the center of the board for more options
- Try to move toward the center when possible
- Avoid moving to squares that have few exit options
- The challenge increases with larger boards!
- Show Numbers: Toggle to display move numbers on visited squares
- Hide Path: Toggle knight's movement path visibility
- Responsive Design: Play on any device size
For more experienced players, try implementing Warnsdorff's rule: always move to the square with the fewest onward moves. This heuristic often leads to a complete tour.
The Knight's Tour problem has been studied for centuries, with mathematicians like Euler contributing to its solution. It's a classic example of a Hamiltonian path problem in graph theory.
On a standard 8x8 chessboard, there are over 26 trillion possible closed knight's tours (where the knight ends on a square that attacks the starting square).
