Off-Grid Sudoku

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.
