Play classic Sudoku without ads or interruptions. Quiet Sudoku works offline and explains the next logical step when you get stuck—so you can enjoy solving and learn along the way. CLASSIC SUDOKU, AT YOUR PACE Choose Easy, Medium, Hard or Expert, with puzzles rated by the techniques needed to solve them. Every puzzle has one solution and a verified logical path. There is no mistake limit, and the timer is optional. Wrong entries are marked against the solution by default; you can switch that off for a fully unassisted solve. Open the app to continue an unfinished game or start today's puzzle. HINTS THAT EXPLAIN First see where to look. Then follow the reasoning and decide whether to apply the step. The guide works with your actual board, and the number keys stay in reach so you can make the move yourself. If a wrong entry is in the way, the guide marks it and lets you erase it in one tap. Learn six techniques, from single candidates to hidden pairs and X-Wings, and practice them on different positions, with guided answers recorded separately from independently correct attempts. COMFORTABLE NUMBER ENTRY Use pencil notes, automatic note cleanup, undo and redo. Notes already ruled out by a number in the same row, column or box are struck through. A compact number row keeps the board in view. Prefer bigger targets? Choose large number keys. A clear notes-mode indicator helps you know whether you are entering an answer or a candidate. A DAILY HABIT, WITHOUT PRESSURE Solve the daily puzzle, revisit completed days or catch up on the past year. Optional local reminders respect your choice; finishing today's puzzle cancels its upcoming reminder. Track your completed puzzles and progress by difficulty. MADE FOR IPHONE AND IPAD Enjoy a larger board in iPad portrait and tools beside the board in landscape. Choose a light paper theme or a dark chalkboard. Local progress saves automatically. Optional iCloud checkpoints let you open a recent game from another device as a separate copy, keeping both devices' progress safe. No ads, subscriptions or in-app purchases in this version. No account registration required. Available in English, Simplified and Traditional Chinese, Japanese, Korean, German, French, Spanish, Portuguese and Italian. ## Is Quiet Sudoku safe?

Swipe to delete one; your records stay. • A finished puzzle shows its completion card right below the board, and starting numbers now say they can’t be changed. • Every move is saved the moment you make it.

Choose a language in Settings or follow your device. • The guide no longer hides the number keys or shrinks the board. Look first, then make the move yourself. • If a wrong entry is in the way, the guide marks it in red and lets you erase it in one tap.

You can turn it off in Settings. • While today's puzzle is in progress, the Today card shows your progress and takes you straight back to it. • Smaller iPhone layout fixes, including opening on the first empty cell. ### 1.0.0 — 2026-10-06 No release notes. ## More apps by jintao LV - [时序日历－纯净无广告万年历](https://appshunter.io/ios/app/id6743664743) - [MengSnap - AI Photo Editor](https://appshunter.io/ios/app/mengsnap-ai-photo-editor/id6744907376) - [Tilely: Time Tracker](https://appshunter.io/ios/app/tilely-time-tracker/id6804098904) - [Important Days: Countdown](https://appshunter.io/ios/app/important-days-countdown/id6804181109) - [Pup Picnic: Dog Sudoku](https://appshunter.io/ios/app/pup-picnic-dog-sudoku/id6810114725) - [VidKeep: Video Saver](https://appshunter.io/ios/app/vidkeep-video-saver/id6816571849) All apps by jintao LV: https://appshunter.io/developer/1619673646 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
