The complete Kakuro combinations chart
This Kakuro combinations chart lists every valid digit set for every clue: pick the run length (2 to 9 cells) and the clue sum, and read off the combinations. Because Kakuro runs use distinct digits from 1 to 9, the possibilities are fixed mathematical facts — a 3-cell run summing to 23 is always 6+8+9, and nothing else.
The chart makes the strongest clues jump out. Sums at the minimum or maximum for their length have exactly one combination: 3 and 4 (or 16 and 17) over 2 cells, 6 and 7 (or 23 and 24) over 3 cells, 10 and 11 (or 29 and 30) over 4 cells. Start with those, then use the crossings between a row run and a column run to eliminate the rest.
A 9-cell run always contains all nine digits and sums to 45 — the same 45 rule that powers Killer Sudoku. Shorter runs near 45-per-length extremes are almost as constrained, which is why experienced solvers keep a printed combinations chart within reach instead of re-deriving sums mid-puzzle.
Each row shows a clue sum and run length with every valid combination of distinct digits 1–9. Unique combinations are the strongest clues — print this chart and keep it beside your puzzle.

How to use a Kakuro combinations chart
- Find the row for your clue: match the run length first, then the sum.
- Read the valid combinations of distinct digits 1–9.
- Prefer clues with a single combination — those digits are forced.
- Cross-check row and column combinations at each shared cell.
- Print the chart and keep it beside the puzzle for quick lookup.
Frequently asked questions
- What does a Kakuro combinations chart show?
- For every run length (2–9 cells) and every reachable clue sum, it lists all valid sets of distinct digits 1–9 that produce that sum. It is a complete lookup table, not a partial cheat sheet.
- Can digits repeat in a Kakuro run?
- No. Every run uses distinct digits from 1 to 9, which is exactly why the chart is finite and fixed — each sum-and-length pair has a definite list of combinations.
- What are the combinations for 23 in 3 cells?
- Exactly one: 6+8+9. Its mirrors at the low end are 6 in 3 cells (only 1+2+3) and 7 in 3 cells (only 1+2+4). Unique sums like these solve their cells outright.
- Can I print this Kakuro combinations chart?
- Yes. The page is formatted as a printable reference table — use your browser’s print function and the chart fits on standard paper for use beside a paper puzzle.
- Why does a 9-cell run always sum to 45?
- A 9-cell run must contain each digit 1–9 exactly once, and 1+2+…+9 = 45. Likewise an 8-cell run summing to S is missing exactly the digit 45−S.
