How to play Sudoku
Fill every empty square so that each row, each column and each of the nine 3×3 boxes contains the digits 1 to 9 exactly once. Every puzzle has exactly one solution and can be solved by logic alone.
Controls
- Tap / click a square to select it, then tap a number on the keypad or type 1–9. Move with the arrow keys.
- Notes (✎ or N) switches to pencil marks; Shift + digit adds a note directly. Placing a number clears that note from its row, column and box.
- Erase (Delete/Backspace), unlimited Undo / Redo (Ctrl+Z / Ctrl+Y), Pause (P).
- Hint reveals the selected (or a random) square; Check marks wrong entries.
