Follow the clues, match the sums, and work out what belongs in each cell.
Kakuro is a number puzzle where each clue gives you a sum to make. Fill each group of connected white cells across or down with digits from 1 to 9 so that they add up to its clue. Within each group, every digit must be different.
Finding a digit in one direction can help you work out the next in the other. Follow the connections between the sums and enjoy watching the numbers fall into place in Kakuro Bird.
