Object: Visit all positions of the board.
 
First click the board to drop your chess Rook. Then move the rook orthogonally as far as you like by clicking on the target square. The length of the move will be marked at the top.
 
You have to use a different length of move every time.
When all lengths are used up, you get a new set of lengths. (The indicators at the top will be reset). Hence on the 6x6 board you have to use 7 sequences of moves, each sequence consisting of 5 moves, having lengths 1, 2, 3, 4, and 5.
 
You may not step on a square you have been to before.
You win when you have visited all squares on the board.
 
The other variants use larger or smaller boards.
Once you have found a solution, drop the Rook on a different square and then try to solve the puzzle.
Is there a solution no matter what square you start on?
 
 
Here are some related questions for the mathematicians amongst you:
- Can you prove that there is a solution for any board size?
- Can you prove that there is a solution for any starting position?
