Enter the across and down runs from your Kakuro puzzle to find a valid digit fill.
Use one run per line in the format: sum: cell,cell. Reuse the same cell ID where a row and column cross.
The sample is a 2x2 Kakuro. You can use names such as A1, A2, B1 for larger puzzles.
The solver finds digits that satisfy every across and down sum while honoring the no-repeat rule.
Start with a small connected area if your puzzle is large. Adding its crossing runs gives the solver the constraints it needs to select valid digits.
If no answer is found, check that every shared cell has exactly the same ID in both lists.
It means cells A1 and A2 make one run whose digits must add up to 16.
No. The solver follows the standard Kakuro rule that a digit cannot repeat inside one across or down run.
