About Sudoku Haven

Sudoku Haven is an offline Sudoku game with more than 450,000 hand-graded puzzles across five difficulties, from Beginner to Extreme. You can take on the Daily Challenge, revisit puzzles in the archive or generate random puzzles.

Solve at your pace

Smart hints nudge you forward without giving away the answer. Notes, auto-candidates and highlighting help with tougher grids, while built-in trainers teach techniques including hidden singles, naked pairs and X-Wing.

Customize and track

Choose from 20 hand-tuned light and dark themes. Stats, streaks and stars track your progress, and soothing music and soft sounds accompany play. The game supports keyboard and controller input.

Frequently asked questions

Steam lets publishers create keys to sell in other shops. Once you activate a key, the game is yours to keep, just like a store purchase.

Disclaimer: CD keys have an inherent 1–2% average failure rate. Check the shop terms for buyer protection info. Steam offers no buyer protection for keys bought in other shops and doesn't refund them.
