Kakuro puzzles are like crosswords with numbers. Fill the white squares with digits 1-9 so the sum of each horizontal block equals the clue on its left, and each vertical block equals the clue on its top. Digits cannot repeat within a block.

Frequently Asked Questions
1. How is the difficulty determined?
Difficulty scales the size of the grid. Easy is 5x5, Medium is 7x7, and Hard is 9x9. The puzzles generated are guaranteed to be solvable and follow standard Kakuro logic rules.
2. Can I export the solution sheet?
Yes! Simply toggle the 'Show Solution' button to reveal all numbers, then use the PNG or SVG export buttons to download the completed version.
3. What is the best format for printing?
SVG is the best format for printing because it is a vector format, meaning it won't lose quality or pixelate even when scaled up to fill a full sheet of paper.
