Sudoku AI — Coach & Learn
Learn techniques, not answers
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
New puzzle every day. An AI coach that explains the technique — not just the answer. Learn X-Wings, hidden pairs, and more while you play.
Sudoku AI is a Sudoku puzzle game with a built-in coach. When you get stuck, ask for a hint and learn the technique behind it — instead of just being shown the answer.
WHAT MAKES IT DIFFERENT
• AI Coaching — Tap the lightbulb anytime for a contextual hint. The 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.
DESIGNED FOR BRAIN TRAINING
Every coaching message names a real Sudoku technique. Over time you'll recognize patterns yourself — 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. Leaderboard entries use auto-generated nicknames (CalmFox-1234 style) so you stay anonymous.
FREE WITH OPTIONAL PREMIUM
Sudoku AI is free to play. Premium unlocks unlimited AI coaching and removes ads. Cancel anytime in your App Store account settings.
PERFECT FOR
• Daily commute or coffee-break puzzles
• Learning Sudoku techniques you've never tried
• Players who want logic puzzles without ads in the middle of a game
• Anyone who wants their brain to feel slightly sharper than it did yesterday
Play offline. No signup required. Numbers, logic, calm.
Sudoku AI Premium is an auto-renewable subscription billed monthly. It renews automatically unless canceled at least 24 hours before the end of the current period. Manage or cancel anytime in your device account settings.
