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!
