About this game

Thirteen ways to play Sudoku — Classic, Killer, Jigsaw, Diagonal and more, all in one app. The rules are simple, the logic runs deep. Whether you have five minutes or an hour, pick a grid and start solving. Every puzzle is generated with a guaranteed single solution, so you never have to guess and you never run out.

🧩 SEVEN VARIANTS INCLUDED
• Classic 9×9 — the Sudoku you know and love
• Killer Sudoku — cages and sums, no starting digits
• Jigsaw Sudoku — irregular regions instead of 3×3 boxes
• Diagonal Sudoku — both main diagonals must also hold 1–9
• Mini 4×4 and Mini 6×6 — quick grids, easy for beginners
• Ice Breaker — a fresh twist on the classic rules

📈 FIVE DIFFICULTY LEVELS
Start at Beginner and work your way up to Expert. Each mode is tuned to your skill — from easy 50-clue puzzles to hard 24-clue challenges that genuinely test your logical thinking. Advanced players will find plenty here to master.

📅 DAILY SUDOKU CHALLENGE
A brand-new puzzle every single day. Track your progress on the monthly calendar, keep a completion streak alive, and see if you can clear a whole month.

🎓 LEARN THE TECHNIQUE, NOT JUST THE ANSWER
Stuck? The built-in coach does not simply fill in a cell for you. It names the technique that applies — Naked Single, Hidden Pair, Locked Candidates, X-Wing — and walks you through the reasoning step by step, so next time you spot it yourself. Use it to move from guesswork to real method, at your own pace. It runs entirely on your device.
