Free printable Kakuro with answers

Kakuro, also called cross-sums, is a crossword-shaped number puzzle. Fill each run of white cells with distinct digits 1 to 9 that add up to the clue in the black cell before it, with no digit repeating in a run. Every puzzle here has exactly one solution.

By size

Size and run length are what make a Kakuro harder: a bigger grid with longer runs has more ways to split each sum. Start on a 5 by 5 and work up to a 7 by 7.

By name and audience

The same puzzle goes by more than one name. Cross-sums, or a gentle grid for a beginner, they all solve the same way.

One answer, proved by a solver

The thing that makes a Kakuro book worth printing is the guarantee most sellers cannot make: that the clues fix exactly one grid of digits. Valid Kakuro generation needs a solver, and every puzzle here is run through one before it prints, with the completed grid as the answer key.

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

  1. 1Read the clues. A number in a black square is the total for the run of white squares to its right or below it.
  2. 2Fill runs with 1 to 9, no repeats. Each run uses digits 1 to 9, and no digit repeats within a single run.
  3. 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.
  4. 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.

How the grades differ
Larger grids with longer runs allow more combinations and need more crossing logic.
