Sudoku AI — Coach & Learn

Sudoku AI is a sudoku coach wrapped in a calm puzzle game. When you get stuck, ask for a hint and learn the technique behind it — instead of just being shown the answer. It's the easiest way to learn sudoku and actually get better. WHAT MAKES IT DIFFERENT • AI Coaching — Tap the lightbulb anytime for a contextual hint. The sudoku coach explains the technique (naked singles, hidden pairs, X-Wings, and more) so you learn while you play. • Four Difficulties — Easy, Medium, Hard, and Expert. Each puzzle is generated to have a unique solution. • Daily Challenge — A new puzzle every day. Single attempt, no hints, no pauses — just you and the board. Submit your time and see where you rank on the global leaderboard. • Calm by Design — A focused, distraction-free board. Subtle haptics. Optional sound. Five themes including a true AMOLED black. LEARN SUDOKU TECHNIQUES, NOT JUST ANSWERS Most apps just hand you the answer. Sudoku AI teaches the sudoku techniques behind it — naked singles, hidden pairs, X-Wings — so over time you recognize the patterns yourself. Every coaching message names a real technique. The coach becomes a safety net you barely need. That's the point. PRIVACY-FIRST No account. No email. No signup. Your stats and progress stay on your device by default.
