A new puzzle every day and a five-year archive to play through. Classic boxes, or Off-Grid regions that bend the rules. Built for one hand.
Find your flow. One thumb, one puzzle a day.
Off-Grid Sudoku is a clean, fast Sudoku built for one-handed play. Tap a number on the pad to arm it, then tap the cells it belongs in — the digit stays armed while you fill them, so you never bounce between board and keypad. Turn on the pencil to jot notes the same way.
DAILY PUZZLE
- Everyone gets the same puzzle each day, at the same difficulty
- Your best time of the day goes to the Game Center leaderboard
- Miss a day? The archive keeps every past puzzle, ready whenever you are
OFF-GRID MODE
- The nine boxes become nine jagged regions — each still holds 1 to 9 exactly once, but the shapes shift with every puzzle
- Rows and columns work as always, so everything you know still applies
- Classic and Off-Grid keep their own records
PLAY YOUR WAY
- Four difficulties, from an easy warm-up to expert
- Pencil notes that clear themselves when a correct digit lands
- Highlight every copy of the selected digit, or turn it off
- Undo, erase, and a hint when you're stuck
- Best and average times per difficulty, and a count of every daily solved
- Haptics, sound effects and a background loop — each with its own switch
No accounts, no sign-ups, no in-app purchases. A short ad plays after a solved puzzle, and in free play you can choose to watch one for a hint. Game Center is optional; the game is fully playable without it.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Weekly leaderboards for each difficulty, and yesterday's board next to today's. Fixed a freeze at the end of a puzzle: the results card could fail to appear after the last digit and the screen stopped responding. An ad that went stale while a puzzle sat in the background is now skipped instead of shown.
