Sudoku, without the noise.
A clean, fast Sudoku for Android. Solve it alone, or share a room code and solve it with three friends at once — everyone on the same grid, in real time.
Sudoku is in closed testing on Google Play and isn't publicly available yet. If you were invited as a tester, use the opt-in link you were sent. If you'd like to be, email support@kiliworld.com.
In the game
The things that actually matter while you're solving, and nothing that isn't.
Pencil marks that behave
Notes toggle per cell and survive a wrong guess — erase the mistake and exactly what you'd pencilled in comes back. Undo covers the rest.
Sixty color palettes
Six theme families, light and dark, five highlight accents. Every palette is generated rather than hand-picked, so all sixty stay legible.
Freshly generated puzzles
Easy, medium and hard, built on demand, each with exactly one solution. You will not see the same grid twice.
Honest mistake tracking
Three mistakes, a running timer, and a best time worth beating. All of it stays on your device.

Solve together
Create a room, share the code, and up to four players work one puzzle at the same time.
- Everyone sees every placement the moment it happens, and sees which cell the others currently have selected.
- Each player gets their own color — chosen so it stays distinct from whatever theme you're playing in.
- Rooms live in memory only. When the last player leaves, the room and everything in it is gone — there's no match history and no leaderboard.
- Your pencil marks stay yours. Notes are never sent to the server or to the other players.

Accounts
Solo play needs nothing. An account is only required for multiplayer rooms, so the other players have something to see you as.
- An account is an email, a password, a display name and one of eight avatar colors. That's the whole of it.
- Passwords are never stored — only a salted PBKDF2-HMAC-SHA256 hash, at 100,000 iterations.
- Your settings, best time and puzzle in progress never leave your device.
- Deleting your account takes one email, and removes everything attached to it.
