Into white fields insert numbers from 1 to 9. White numbers in black fields are sums of the inserted numbers (e.g. 23 = 9 + 6 + 8). The number above the diagonal line is the sum of the numbers on the right, and the number under the diagonal line is the sum of the numbers underneath this line. The numbers cannot repeat within one sum. Every puzzle has exactly one and only one solution.
