About this app
Sudoku Haven is a calmer way to play Sudoku — 450,000+ hand-graded puzzles, a daily challenge, and 20 quiet themes, free and offline. It's a quiet place for your mind on iPhone and iPad, too: soft light, unhurried numbers, and room to breathe between moves. Every puzzle is hand-graded across five difficulties, from gentle Beginner grids to genuinely challenging Extreme. Play a fresh Daily Challenge every day, return to any puzzle in the archive, or generate endless random puzzles whenever you like. Everything is built to keep you in flow: • Smart hints that nudge you forward instead of handing you the answer • Notes, auto-candidates, and gentle highlighting that make tough puzzles approachable • Built-in trainers that teach real solving techniques — hidden singles, naked pairs, X-Wing, and more • 20 hand-tuned themes, light and dark — make the board truly yours • Stats, streaks, and stars that quietly track your progress • A relaxing brain workout you can play offline, with soothing music and soft sound No clutter, no pressure — just you and the next square. Sudoku Haven goes everywhere you do. Glance at the daily puzzle and your streak on your Apple Watch, and challenge a friend to a board right inside iMessage. Compare solve times on Game Center leaderboards, earn achievements, and keep everything in sync across iPhone and iPad with iCloud. A friendly head-to-head multiplayer mode is in mind, too — and the more players who find the Haven, the sooner it arrives. Free to play, with one optional purchase that removes ads and opens up everything. Find your calm and start solving.
