Kakuro Maker
Kakuro is the number-logic cousin of sudoku — sometimes called cross-sums. Fill each run of white cells with digits from 1 to 9 so the run adds up to the clue in its black cell, with no digit repeated inside a run. Choose 8 × 8, 10 × 10 or 12 × 12 grids at three difficulty levels, solve on screen, and print or download as PDF with an answers option.
How to use the kakuro maker
Choose a grid size and difficulty, and a fresh puzzle appears instantly — every puzzle is different, and no two puzzles on a page share the same layout.
- Reading the clues: in each black cell the top-right number is the sum of the white cells to its right; the bottom-left number is the sum of the white cells below it.
- Solving: start with the shortest runs — a run of two cells with a clue of 3 must be 1 and 2, so any cell they share with a crossing run is instantly narrowed down.
- Solve on screen: click a white cell and type a digit, or use the arrow keys to move between cells. Check highlights anything wrong.
- Printing: “Print / PDF” prints the blank puzzle — up to 2 per sheet. “Print Answers” prints the completed grid.
