About this app
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. THE DETAILS • Pencil notes with a dedicated notes row, no mode switching • Completed numbers fade on the pad • Auto-save: close the app mid-puzzle, resume exactly there • Statistics, best times, total play time • Light and warm-dark themes • Optional background music, gentle click sounds and haptics — all respectful of your mute switch and your own music Free forever. If it brings you a little peace, there's a small tip jar, thank youuuuu nothing unlocks, the whole app is already yours. Lets make this world a beter place.
