One inbox, and a real person reads it.
What to write about
- Bugs — if a puzzle, timer, or multiplayer room misbehaves, tell us what you were doing and which browser you use. Screenshots help a lot.
- Feedback and ideas — a game mode you want, something that annoys you, a rough edge on mobile. This is genuinely how the site improves.
- Privacy requests — to delete your account and its stats, email from your own address and tell us your username. See the Privacy Policy.
- Translations — Sudokusama is available in six languages. If something reads awkwardly in yours, we would like to know.
- Business — advertising, partnerships, or press.
Before you write
If you are stuck on a puzzle rather than hitting a bug, our How to Play guide and strategy tips cover almost everything — including a checklist for when a grid refuses to budge. A properly made Sudoku never requires a guess.
Response time
Sudokusama is run by a very small team, so replies are not instant — but every message is read.
