About this game

Sudoku Duel is the classic logic puzzle, redesigned around two things you can't get from any other Sudoku app: a real-time 1v1 Battle Mode and a fresh Daily Challenge that everyone races on the same board.

βš” BATTLE MODE
Generate a room code, share it with a friend in one tap, and race them on identical puzzles in real time. Watch their progress fill the bar opposite yours. First to a clean board wins. No accounts, no signups β€” just the link.

πŸ—“ DAILY CHALLENGE
Every player gets the same puzzle each day. Beat it before midnight to keep your streak alive. Simple, addictive, and exactly the right size for your morning coffee.

πŸ”₯ WIN STREAKS
Solve at least one puzzle a day and your streak grows. Miss a day, it resets. The 7pm reminder is opt-in and stays on your device.

🧩 FOUR DIFFICULTY LEVELS
Easy, Medium, Hard, and Expert β€” each generated fresh, each guaranteed to have exactly one solution. No back-tracking dead ends. Ever.

⚑ TWO INPUT MODES
Lightning (number first, like the modern apps) or Classic (cell first). Switch any time from Settings.

✏️ THOUGHTFUL ASSISTANCE
Smart pencil marks that auto-dim when invalid. Optional error highlighting. Optional auto-removal of obsolete notes when you place a digit. Configure as much or as little help as you want.

πŸ”’ PRIVACY-FIRST
No accounts. No tracking by default. iOS App Tracking Transparency is honoured. Delete every byte of your data with one tap from Settings. Privacy policy linked in-app.

πŸ“΅ 100% AD-FREE
v1 ships completely ad-free. No interstitials, no banners, no upsells. Just Sudoku.

Whether you're a daily-puzzle person or you've been waiting for a way to play head-to-head with a friend across the room (or across the world), Sudoku Duel is the cleanest way to do it.
