About Kakuro
Kakuro (cross-sums) is a numeric crossword: fill each run of cells with digits 1–9 that sum to the clue at its end, without repeating digits within a run.
Tips
- Memorize small-sum combinations — e.g. 16 in three cells is nearly always 7+8+1 variants.
- Unique-combination clues (like 3 in two cells = 1+2) are the best starting points.
- Cross-check vertical and horizontal sums where runs intersect.
FAQ
- How is Kakuro different from Sudoku?
- Both restrict repeated digits, but Kakuro adds arithmetic: each run must sum exactly to its clue.
