Sudoku Academy: Learn & Solve

Most Sudoku apps just give you a grid. Sudoku Academy actually makes you better at it.

WHAT MAKES IT DIFFERENT
• TECHNIQUE ACADEMY - a road map of 8 chapters and 160 levels, one chapter per solving technique (Naked Single, Hidden Single, Naked Pair, Box-Line, X-Wing, XY-Wing, Swordfish, Forcing Chain). Each chapter opens with a lesson on a real board position where that technique applies: the pattern is ringed on the grid, the candidates it rules out are struck through, then you find the cell yourself. Then 19 practice boards where you spot it on your own, each rated 1-3 stars. Every level is open from the start.
• The game NAMES YOUR MOVES - solve a Naked Single or a Hidden Single in a normal game and it says so, right on the board.
• A hint coach that TEACHES - in a normal game a hint can name and explain the technique in play instead of just filling a number in.
• GLOBAL LEADERBOARD - fastest solve per difficulty, with a nickname and flag you choose. No account and no email.
• Adventure mode - 100 levels across 5 themed chapters, each with a 1-3 star rating for speed and solving without reveals.
• Daily Challenge - a fresh deterministic puzzle every day with streak tracking.

ALSO INSIDE
• 5 difficulties: Easy, Medium, Hard, Expert, Diabolical
• Power-ups: Reveal Cell, Auto-Notes, Mistake Check
• 3 hand-tuned themes (light / dark / sepia)
• Pencil notes, undo/redo, auto-save, mistake modes
• Play 100% offline, 15 languages, no sign-up

Learn the techniques, climb the Adventure, keep your daily streak alive.
