A relaxed chess puzzle: guide the knight across every square exactly once. Choose 5x5 to 9x9, undo freely, and use verified hints when you want help.

Choose any starting square. Then move like a knight: two squares in one direction, one square sideways.

How to play

Pick a board from 5x5 to 9x9.
Click any square to start.
Each next move must be a legal knight move.
Win by visiting every square once.

Best starting point

There is no pressure. Start anywhere, undo when needed, or press Hint before your first move for a solver-approved start.

Correct hint rule

The hint button runs a completion search. A square is highlighted only if the solver has already found a full open tour that continues from it.

If no hint appears

Your current route may be trapped, or the search took too long. Undo one or more moves and ask again.

Hint cache

When you follow a verified hint, the next hint is faster because the game remembers the verified route. If you choose a different move, it checks again.
