If you think it was impossible to solve Sum Spots, there is something missing on instruction. Instruction only gives the same sum on rows, columns and two diagonals. Whats is missing is that the same sum on the four center squares and the four corner squares. It's best to start at the center squares or one of corner squares which has one number inserted. However there are assumptions which may start out with same sums as many four to six assumptions. Best way to do assumptions is to use Excel so you can copy many of them to try all assumptions.
