No ads. No video after every puzzle. No account. Hints put you on the right track instead of giving away the digit. Over time that gets you onto levels you cannot handle today. HINTS IN THREE STEPS First step: which technique applies, and in which area. Second: the exact spot. Third: the digit, or for a pattern the notes it removes. You stop whenever you have enough. Ordinary hint buttons fill in a cell right away. 20 LESSONS From scanning to advanced patterns. 17 of them show their technique in examples on the board. YOU SEE WHAT STICKS After every move the app knows which technique was due, and it remembers whether you spotted it yourself or had it shown to you. That becomes a bar per technique that fills until the technique is solid. No percentages. PLAYING FOR FREE Easy and Medium unlimited, with all hints and notes. Plus the Daily Challenge every day, on every level up to Expert. Plus unlocks Hard and Expert permanently. DAILY CHALLENGE The same puzzle worldwide, one per day. Solving it counts toward your streak. NO GUESSING REQUIRED Not even on Expert. Most apps only check that a puzzle has exactly one solution. Whether a person can find it without trial and error is a different question. Sudoku Still also runs every board through a solver that knows only human techniques, and discards what it cannot finish. LEVELS BY TECHNIQUE A puzzle's level depends on the hardest technique it requires, not on how many digits are missing. Hard is therefore equally hard every day. NOTES THAT KEEP COUNT Candidate notes update themselves when you enter a digit, and a hint reads your current notes and carries on from there. Not a rebuild of paper and pencil, but what a screen can actually do. SMALL AND OFFLINE Smaller than a photo. Runs without a connection and without video, which goes easy on the battery. Collects no data at all. ALSO On the iPhone Duo, the board and the controls each take one half when it is open sideways or standing half open. Streak, level and best times live in your iCloud, on iPhone and iPad, with no account and no sign-in. Siri and Shortcuts answer your streak and best time without the app opening, and the lessons are in Spotlight. SUDOKU STILL PLUS Plus opens up "Hard" and "Expert" in free play: boards where the patterns from the tutorial are actually needed, as often as you like. Family Sharing makes one subscription count for everyone in your family. Without Plus, Easy and Medium and the Daily Challenge stay fully open. Sudoku Still Plus is an auto-renewable subscription (monthly or yearly). Payment is charged to your Apple Account at confirmation of purchase. It renews for the same period unless canceled at least 24 hours before the end of the current period. Manage and cancel it in your Apple Account settings after purchase.

Open and turned sideways, the board and the digits each take one half. Half open on a table, the board sits on top. ### 1.4 — 2026-10-04 PROGRESS PER TECHNIQUE In Statistics, each technique fills a bar until it is solid. Every step you find yourself moves it along, and once a technique is solid, it stays that way. After a solved puzzle, the app tells you which technique you found on your own for the first time and which one is now solid. HINTS Hints speak to you directly and tell you what you can do. Which notes to cross out is only shown at the last step. ### 1.3 — 2026-09-30 NOTES A note now sets reliably as soon as you briefly hold a digit. HINTS The hint button hides an open hint again. The next step comes from "Next hint" in the hint itself. ### 1.2 — 2026-09-19 HINTS Get to the technique description right from the respective hint. It lays the lesson over the game. Show the next level hint by hitting "Next hint". NOTES A note appears as soon as you briefly hold the digit. Holding had become noticeably slow. Many other improvements. ### 1.1 — 2026-08-31 PROGRESS PER TECHNIQUE After every move the app knows which technique was due, and it remembers whether you spotted it yourself or had it shown to you. Your statistics turn that into one state per technique: new, building, solid. Every solved game also shows how it came about, and each difficulty tells you how many you solved without hints. ON IPAD A sidebar leads to play, scoreboard, statistics and techniques, instead of each area covering the whole screen. Board, controls and text columns only grow to a sensible size: extra space becomes calm rather than huge cells. Lessons sit in two columns, example board beside text. A connected keyboard plays the game: enter digits, erase, notes mode, hint, pause. Font sizes follow your text size setting. A locked difficulty now tells you when it runs free in the Daily Challenge, with a button that takes you straight there. The 4×4 board is gone; the way in is "Easy". ## Apps similar to Sudoku Still | App | Rating | Price | Category | | --- | --- | --- | --- | | [Puzzle Master: Sliding Tiles](https://appshunter.io/ios/app/puzzle-master-sliding-tiles/id6754782354) | — | Free | Games | | [Daxtle](https://appshunter.io/ios/app/daxtle/id6762006702) | — | Free | Games | | [Orixo Hex](https://appshunter.io/ios/app/orixo-hex/id1616456720) | 4.8 (405) | Free | Games | | [™ Sudoku](https://appshunter.io/ios/app/sudoku/id1387281887) | 4.4 (121) | Free | Games | | [Enjoy Sudoku](https://appshunter.io/ios/app/enjoy-sudoku/id6466218894) | 2.0 (4) | Free | Games | | [Nurikabe: Islands & Walls](https://appshunter.io/ios/app/nurikabe-islands-and-walls/id581912445) | 4.9 (399) | Free | Games | ## More apps by Kornelius Brunner - [Feedwright: RSS Feed Reader](https://appshunter.io/ios/app/feedwright-rss-feed-reader/id6793821077) - [Peal: Alarm for Appointments](https://appshunter.io/ios/app/peal-alarm-for-appointments/id6808315934) All apps by Kornelius Brunner: https://appshunter.io/developer/6792647622 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
