Daily Sudoku: One a Day

One puzzle a day. Three levels. No account, no timer pressure, no clutter.

Daily Sudoku gives you a fresh set of three puzzles every morning - Easy, Medium, and Hard. Everyone playing on the same day gets the same puzzles, generated right on your device, so you can play anywhere, even with no signal.

Clear one puzzle a day to build a streak. Miss a day and it resets. That is the whole game.

WHAT YOU GET

- Three puzzles every day - Easy, Medium and Hard, refreshed at midnight
- Unlimited practice puzzles when one a day is not enough
- Every puzzle has exactly one solution, verified before it reaches you
- A streak counter that rewards showing up, not grinding
- Pencil marks with automatic cleanup when you place a number
- Undo any number of steps, including the notes cleared along the way
- Mistakes are flagged the moment you make them, so you never chase a dead board
- One free hint per puzzle, and no puzzle ever needs one
- Your progress is saved automatically - close the app mid-puzzle and pick it up later
- Works completely offline
- Portrait and landscape, physical keyboard supported

BUILT TO STAY OUT OF THE WAY

No sign-up. No cloud sync. No daily reward wheel, no energy meter, no pop-ups between moves. Ads appear only between puzzles, never while you are solving.

The app is free and supported by ads. Watching an optional video ad gives you an extra hint if you want one - but every puzzle is solvable without it.

Available in English and Japanese.
