Click or tap a square, then a number button. On a keyboard, use the arrow keys and number keys; Backspace clears a square.

About the game

Fill the grid so that every row, every column and every 3×3 box contains the numbers 1 to 9 exactly once. Some numbers are already given. Select an empty square and choose a number from the buttons below the grid. Correct numbers turn green and wrong ones turn red. Your score counts the squares you have filled correctly.

How to play

Tips

  • Look for rows, columns or boxes that are almost full.
  • For each empty square, rule out numbers already in its row, column and box.
  • When only one square in a box can hold a number, it must go there.
