About This Game

Sudoku Haven is a calmer way to play Sudoku — 450,000+ hand-graded puzzles, fully unlocked and offline — no ads, no in-app purchases. It's a quiet place for your mind, 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 with keyboard and controller support, soothing music, and soft sound

No clutter, no pressure — just you and the next square.

Fully unlocked: no ads, no in-app purchases — just the complete game, playable offline.

A friendly head-to-head multiplayer mode is in mind, too — and the more players who find the Haven, the sooner it arrives.

Find your calm and start solving.
