How to Use the Kakuro Solver
1
Enter the Number of Cells
Count how many white cells are in the run you're trying to solve (2–9).
2
Enter the Target Sum
This is the clue number — the sum the digits in the run must add up to.
3
Optionally Exclude Digits
If you already know certain digits can't appear in this run (due to intersecting runs), exclude them to narrow results.
4
Review Combinations
The solver shows every valid combination. Use this to deduce which digits belong in which cells.
