Sudoku Still: Learn Sudoku

No ads. No video after every puzzle. No account. Hints name the technique before they name the digit. Over time that gets you onto levels you cannot handle today. HINTS IN THREE STEPS First step: where to look. Second: which technique applies here. Third: the digit. You stop whenever you have enough. Ordinary hint buttons fill in a cell right away. 20 LESSONS From scanning to advanced patterns. Each lesson is a puzzle with guidance, not a chapter of text. 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 one state per technique: new, building, solid. No percentages, no charts. PLAYING FOR FREE Easy and Medium unlimited, with all hints and note features. 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 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.
