Sudoku Mates
Take your time.
Or take on the table.
Fill each row, column and 3×3 box with the digits 1–9 exactly once. Play on your own, or solve the same puzzle as other players with a shared start.

Practice
Choose a difficulty and solve at your own pace. Use pencil notes to keep track of possibilities. In browser Practice, you can choose whether to highlight mistakes and pause the timer when you need a break. Progress and notes stay on that device.
Daily
Browser Daily offers one attempt per player profile each UTC day. Players get their own random puzzle under the day's published conditions. The server saves the attempt and the timer keeps running while you are away. After finishing, compare completed results. Browser Daily needs a connection; the mobile app's local Daily works differently.
A race with friends
Create or join a room by link or code. Ready players start together on the same puzzle, while each player fills their own board. Rivals see progress and mistakes, not your entered digits or notes. The room's rules control assists and the mistake limit.
Your profile, your choice
You can begin as Nobody without registering. A credential on your device reconnects that profile. Optional account saving is available through the sign-in methods offered by the game. Signing in does not move local Practice progress or pencil notes between devices.
The game has its own data handling, settings and support. This catalogue does not sign you in, start a session or store your progress.
