Most Sudoku apps give you the answer. Sudoku Master teaches you how to find it. Every hint works in three steps. First it shows you where to look. Then it explains why. Only if you ask does it fill in the digit — and only that step costs points. Each hint names the technique it used and links to its lesson, so the next time that pattern appears you'll spot it yourself. HINTS THAT TEACH • Where to look → why → the answer, one step at a time • Hints respect your pencil marks and work from your notes • Wrong entries are explained: which cell or house clashes, and why LEARN THE TECHNIQUES • Illustrated lessons for fourteen techniques, from Scanning and Hidden Singles through Pointing and Naked Pairs to X-Wing, Swordfish and XY-Wing • Practice mode: drops you into a real puzzle at the exact moment that technique is the next step, pencil marks already in • The Rules, a 16×16 guide, an X-Sudoku guide, a glossary and a solving routine used by strong players PUZZLES YOU CAN TRUST • 9×9, giant 16×16 grids (digits plus A–G), and X-Sudoku, where both long diagonals must hold every digit too • Easy, Medium, Hard and Expert — every puzzle verified to have exactly one solution, so it never needs guessing • Easy puzzles need only singles; Hard and Expert genuinely need the advanced techniques • Puzzle Info shows which techniques the solver needed, so you know what to look for • Daily Challenge — the same puzzle for everyone, with streaks BUILT FOR THINKING • Pencil marks, auto-notes, unlimited undo and redo • Hold a number to pencil it in • Row, column and box highlighting; matching-digit highlighting • Optional mistake checking and three-mistake limit — or play it like paper • Statistics, best times and scoring that rewards clean solving • Share your result when you solve • Six colour themes, light and dark mode COMPETE AND KEEP THE STREAK • Game Center: weekly best-time leaderboards for every difficulty, an all-time daily-streak board and 15 achievements • Home and Lock Screen widgets for the Daily Challenge • An optional daily reminder at a time you choose IPHONE AND IPAD • Full landscape layouts on iPhone and iPad • Hardware keyboard support on iPad: digits, arrows, undo, notes and hints • Progress, statistics and achievements sync between your devices with iCloud FREE, WITH ONE OPTIONAL PURCHASE Play unlimited 9×9 puzzles, X-Sudoku, the Daily Challenge and the Basics and Intermediate lessons for free, with three explained hints a day.
