A local puzzle shelf

No player account needed.

The game saves boards, undo history, checks, hint counts and solved states in local browser storage. It does not upload player progress to a product backend.

Restart a cabinet to reset that puzzle’s record. Clear this site's browser data to remove all stored progress. Downloaded copies remain wherever you saved them.
