Contact & Support
Sudoked.com is an independent Sudoku project created and developed by Andrus Aasmäe. Questions, suggestions and reports of problems are welcome.
Write to mnemonemo3@gmail.com for help with the game, corrections to technique explanations, or questions about the project. You can also open the game page and choose Feedback in its navigation. The feedback form delivers messages through FormSubmit; include an email address if you would like a reply.
Before reporting a problem, the Help & FAQ page may answer your question about saved progress, hints or installing the game.
Report a game problem
A useful report includes:
- The page URL, puzzle number and difficulty, when available.
- What you were doing, what happened, and what you expected to happen.
- Your browser and device, and whether you were using a browser tab or an installed version.
- A screenshot of the board or error, if it helps explain the problem.
Please do not clear browser data while trying to report missing progress: it can remove the saved game and statistics. Do not include passwords, Google authorization codes or access tokens in messages or screenshots.
Suggest a correction
If a hint or technique explanation seems wrong, send the technique page URL or a screenshot of the hint, together with the relevant grid and pencil marks. Explain which deduction appears incorrect. Reports help us reproduce the position and check the explanation. Read how we check puzzles and explanations.
