How to Play Kakuro
- Fill white cells with digits 1–9.
- Each horizontal or vertical run must add up to the clue number shown in black cells.
- No digit can repeat within the same run.
- Use logic and elimination to deduce which digits fit where.
Tips & Strategy
- Start with runs that have few possible combinations (like 3 in 2 cells = 1+2).
- Note which digits are already used in intersecting runs to eliminate options.
- Unique sums help: 45 is the only way to fill 9 cells (1+2+3+...+9).
Kakuro — Frequently Asked Questions
How is Kakuro different from Sudoku?
Sudoku forbids repeats in rows/columns/boxes. Kakuro requires digits in each run to sum to a specific total with no repeats.
Are there multiple solutions?
No, every valid Kakuro puzzle has exactly one unique solution solvable through pure logic.
