How to play Sudoku
- Fill the 9×9 grid so every row, column and 3×3 box contains the digits 1–9 exactly once.
- Click a cell to select it, then click a number below (or press 1–9 on your keyboard).
- Use Backspace to erase, arrow keys to move, and the Hint button when you're stuck.
- Wrong entries are shown in red — the fewer mistakes, the better!
