Master Sudoku — From Beginner to Grandmaster
Snap a photo of any puzzle from a newspaper or book and watch it spring to life on your screen — or generate fresh challenges anytime across five difficulty levels: Easy, Medium, Hard, Expert, and bone-crushing Fiendish.
Whether you're a casual solver or chasing your next skill level, powerful tools are always on hand: candidate highlighting, smart hints, and one-tap automated eliminations to keep your grid clean.
Turn every puzzle into a lesson. Our intelligent hint engine doesn't just hand you the answer — it shows you the simplest logical step available, names the exact technique behind it, and lets you tap to highlight the very cells that prove it. Watch the logic unfold, then apply it yourself next time.
Go from Naked Singles to Franken Swordfish. The app teaches and applies an arsenal of advanced solving techniques, including:
Naked/Hidden Singles
Naked Pairs & Hidden Pairs
Pointing Pairs
X-Wing, XY-Wing & XYZ-Wing
WXYZ-Wing & W-Wing
XY-Chains
Swordfish & Franken Swordfish
Skyscraper
Jellyfish
Follow the hints enough times and you'll start spotting these patterns on your own — no hints required. And with fully customizable help settings, you decide exactly how much (or how little) guidance the app gives you, so it grows with you from first-timer to solving savant.
