Reporting a problem
Describe what you expected and what happened. Include your browser, device, game difficulty, and the date if you were playing a daily puzzle. A screenshot can help, but check that it does not include personal information.
For an unexpected result, mention whether you used notes, number-first entry, or a hint. You do not need to share your browser storage or any account credentials.
Missing progress?
Check that you opened the same website address in the same browser. Private browsing and cleared browser data can remove saved progress. If another tab changed the saved game, use Reload saved game to continue from its latest save.
The game currently has no cloud backup. We cannot recover a save that your browser has deleted.
A difficult puzzle?
Hint first points you toward a move, then offers an explanation. The teaching hints cover singles. When the game cannot explain a supported move, it clearly offers an answer reveal instead. The strategies guide explains more ways to work with pencil notes.
