How to play Kakuro
- Put a digit from 1 to 9 into every white cell.
- Read the upper-right clue across to the right, or the lower-left clue down the column.
- Add the digits in that uninterrupted run. Their total must match its clue.
- Use a digit only once within each run. Every white cell must satisfy both its across sum and its down sum.
For two cells with a sum of 3, the digits must be 1 and 2, in some order. The crossing clues tell you which digit goes where.
| Across / down | 4 down | 6 down |
|---|---|---|
| 3 across | 1 | 2 |
| 7 across | 3 | 4 |
Rule reference: Nikoli’s Kakuro rules. These four grids and their layouts are original to Puzzku.
Print a compact cross-sums activity
Each sheet has one 5 × 5 grid with twelve white cells and large writing spaces. The other cells hold sums or separate runs. Give everyone the same puzzle ID for a group discussion, or use the picker to hand out a shorter selection.
Match puzzle and answer sheets by K-01 through K-04. Changing paper size does not change the answer. A small grid is a format choice, not a tested difficulty or age rating.
Choose sheets for your group
Choose one to four puzzle IDs, their order, and the paper size. This picker uses the fixed collection of 4 puzzles; it does not create an unlimited supply. Moving past the last ID wraps to the first.
Selected IDs: K-01, K-02, K-03, K-04. Answers use the same IDs.

Common questions
What do the two numbers in a clue cell mean?
The upper-right number is the sum of the white cells to its right. The lower-left number is the sum of the white cells below it. A run stops at a dark cell or the edge of the grid.
Can I repeat a number or use zero?
Use digits 1 through 9 only. Do not repeat a digit inside one across run or one down run. The same digit may appear elsewhere when it belongs to different runs.
Does each puzzle have one answer?
Yes. All four published grids are checked for exactly one solution using the sums and the no-repeat rule. Their solving time and difficulty have not been calibrated.
Are these an unlimited Kakuro generator?
No. This is a fixed collection of four original 5 by 5 grids, each containing twelve white cells. The picker changes which sheets you print, their order, and their paper size.
