Contact
Sudoku Games is run by a small independent team. There are two ways to reach us, and a person reads both.
Emailcontact@sudokugames.onlineBest for anything detailed — a bug report, a privacy request, or anything commercial.
SocialFacebook · InstagramA message on either account reaches us too, and is usually the quicker of the two for a short question.
Most questions are already answered
Not to wave you off — it is genuinely faster. The great majority of what reaches us is one of four things, and each has a page that answers it properly:
- "Is my grid actually solvable?" — paste it into the solver. It tells you whether a puzzle has exactly one solution, none at all, or several, which is usually the real answer when a grid refuses to work out.
- "I am stuck and I think the puzzle is wrong." — it almost never is. The techniques guide covers the nine deductions in the order you need them, and a stuck board is nearly always one specific technique away.
- "How does scoring work?" — the leaderboard page sets out the full table: what each level is worth, the par times, and what mistakes and hints cost.
- "Can I put the board on my site?" — yes, free. The widget page has the code and the setup guide; no need to ask first.
The FAQ covers the rest, including the question everyone asks: no, a well-formed Sudoku never requires guessing.
What to write about
A puzzle looks wrong
This is the most useful kind of report. Tell us the difficulty level, roughly how far in you were, and what looked wrong — for example a square that seemed to accept no valid digit, or a solve that was rejected despite following the rules. Puzzles are generated on your device and verified for uniqueness before display, so a genuine fault here is something we want to chase down.
A bug or something broken
Please include your browser and, if it matters, whether you were on a phone or a computer. Layout problems, controls that do not respond, and lost progress are all worth reporting.
Accessibility
If something is unusable with a keyboard or a screen reader, or if contrast is too low to read comfortably in either theme, tell us. These reports get priority.
Removing a leaderboard entry
Send the nickname and roughly when it was posted and we will remove it. Entries also expire on their own — see the privacy policy for the timings.
Running the board on your own site
The embed needs no permission and no key, so most people never need to write at all. Do get in touch if it will not fit your layout, if your content security policy is blocking the frame, or if you need something the widget cannot currently do — those are worth hearing about.
Advertising and business
For advertising enquiries or anything commercial, use the same address and put "advertising" in the subject line.
Privacy requests
Requests to access or delete information should go to the same address. The privacy policy sets out what we actually hold, which is very little.
What we cannot help with
We do not provide solutions to puzzles from other sites or from newspapers, and we cannot recover a game lost to cleared browser data — saved games live only on your own device and are never uploaded.
