Ad-free sudoku game that helps
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Free. No ads. No tracking. No nonsense. Just calm puzzles and hints that teach real technique — now with full-screen landscape play, for left and right hands alike.
Sudoku the way it should feel: quiet.
No disturbing ads you need to watch first.
Zen Sudoku is a completely ad-free sudoku on warm paper tones, with
serif numerals and ink-brush illustrations. No accounts, no tracking,
no internet connection at all, the app cannot interrupt you, because
it has nothing to interrupt you with.
Whether you are a beginner or expert, we got you!
THE APP THAT TEACHES
The hint button never just hands you an answer. It names a real solving
technique, shows you where to look, and only fills in a cell if you ask
it to. It reads your pencil marks, warns when one is impossible, and
nudges you to mark the right area when a pattern is hiding. Tap "what
is this?" on any technique for a plain-language lesson, from naked
singles all the way to X-wings and Y-wings.
EVERY PUZZLE IS FAIR
Puzzles are generated on your device and verified by the same logic
engine that powers the hints: every puzzle can be solved by pure
reasoning. No guessing, ever. Four difficulties, Expert really means
expert techniques, not trial and error.
