About this game

Skudo — Sudoku that finally feels alive! 🧩

No sign-up. Just open the app and play — Classic and Killer Sudoku, a daily brain workout, a real-time AI rival, and online matches with friends.

Most Sudoku apps leave you solving alone in silence. Skudo gives you an opponent who actually plays: a smart bot that races you cell by cell, pauses at the hard spots, and pushes back — 100% offline. Beat it, then climb the ladder toward tougher rivals.

🎮 KEY FEATURES
✅ Classic & Killer Sudoku — Thousands of puzzles, from Easy to Expert
✅ Easiest Sudoku — Smaller 4×4 & 6×6 boards (Classic & Killer) to warm up or learn
✅ Real-time AI rival — Race a smart on-device bot cell by cell, 100% offline
✅ Smart Hints — Learn the technique behind each move, not just the answer
✅ Daily Challenge — One fresh, hand-tuned puzzle every day
✅ Online Multiplayer — Versus & Co-op: create a room, share a code, play with friends
✅ Full offline support — Solo puzzles, bot matches, and hints all work with no internet
✅ Beautiful UI — Modern design, smooth animations, dark mode
✅ Multi-language — English & Vietnamese
