How to play Place numbers in the empty squares by clicking or tapping a number on
the pale blue row and then clicking or tapping in the chosen blank square on the puzzle. As you fill in
the empty squares, the sum must equal the given clues across and down. Top numbers are across, bottom numbers down.
Also you can’t have the same number in two places in an answer e.g. 12 might be 6 2 4 but not 2 5 5.
When you have completed the puzzle, if you don’t get a Congratulations message, use the

Show Solution button.
