Kakuro, or cross-sums, is a crossword-shaped number puzzle. Fill each run of white cells with distinct digits 1 to 9 so the run adds up to the clue printed in the black cell before it. No digit repeats within a run.

Is this Kakuro generator free?

Yes. Pick a difficulty, generate a puzzle and print the grid plus its answer, with no sign-up and no watermark. It is free for classroom, home and personal use.

Does every puzzle have one solution?

Yes. Every puzzle is generated and checked by a solver so the clues fix exactly one grid of digits. A puzzle is never ambiguous or unsolvable.

Does it include the answer?

Yes. Every puzzle prints as two pages: the clues on page one and the completed grid on page two, so you can check your work.

What size are the pages?

The free tool prints at 8.25 by 11 inches, a popular large-print size. Our Publisher Studio will export the same book at any KDP trim, from 5.06 by 7.81 up to 8.27 by 11.69, as a print-ready 300 DPI interior.
