About this game

Sudoku the way it should be — no ads, no tracking, no sign-up. Just you and the puzzle.

Most free Sudoku apps interrupt you with ads, ask you to watch a video for a hint, or quietly track what you do. This Sudoku doesn't. It's a clean, calm, offline number puzzle built by an independent developer who just wanted a quiet place to play Sudoku and train the brain.

WHY YOU'LL LIKE THIS SUDOKU
- No ads. Not one — not even "watch a video for a hint." A promise, not a trial.
- No sign-up, no account. Open the app and you're playing in two seconds.
- No tracking, no data collection. What happens on your phone stays there.
- 100% offline. Play this Sudoku anywhere — no signal needed.
