Off-Grid Sudoku

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.
