Kakuro Combinations

Find all possible combinations for a sum

This page finds all possible sum combinations given the criteria. In Kakuro, sums must be built with the numbers between 1 and 9, whereby each number may only appear once. For example, the numbers of three fields which have to add up to 8 could be 1 + 2 + 5 or 1 + 3 + 4, in any order.
