New to Sudoku? Here’s how to play.

The aim is to complete the grid with the numbers 1 to 9, without repeating a number in a row, column or 3 × 3 box.

  1. Look at the grid

    Use the numbers already given to narrow down what can go in each empty cell.

  2. Check three places

    Before placing a number, check its row, column and 3 × 3 box.

  3. Build your solution

    Keep working through the grid until every row, column and box is complete.
