How to solve a kakuro

Kakuro is a crossword done with numbers: fill each run of white squares with digits that add up to its clue.

The method

1Read the clues. A number in a black square is the total for the run of white squares to its right or below it.
2Fill runs with 1 to 9, no repeats. Each run uses digits 1 to 9, and no digit repeats within a single run.
3Start with the tight runs. A two-square run adding to 3 can only be 1 and 2. Short runs and extreme totals have few combinations, so begin there.
4Use the crossings. Every white square sits in an across run and a down run. A digit must satisfy both, which quickly narrows the choices.

The one rule: Fill the white squares so each run adds to its clue, using 1 to 9 with no repeat in a run.
What the answer page shows: The filled grid is printed at the back.
How the grades differ: Larger grids with longer runs allow more combinations and need more crossing logic.
Good for: Solvers who enjoy sums and the crossword-style grid.
