Free Printable Kakuro Puzzles
Kakuro, sold in American puzzle magazines as Cross Sums, is a crossword filled with digits instead of letters. Each white square gets a digit from 1 to 9, each run of white squares totals the clue in the black square that starts it, and a run never uses the same digit twice.
Four grid sizes are offered, from a small 6x6 to a large 12x12, at three levels each, and the 6x6 and 8x8 grids are also printed four per sheet. A single solution awaits in every grid, found by reasoning alone.

About the kakuro puzzles
How kakuro works
Black squares hold the clues, split by a diagonal: the number above the line is the total of the white run to its right, and the number below it the total of the run underneath.
- Digits: 1 to 9 only, one in each white square.
- No repeats: a run never holds the same digit twice, so a clue of 4 over two squares means 1 and 3, never 2 and 2.
Kakuro grid sizes: from 6x6 to 12x12
- 6x6: runs of five squares at most, a gentle first grid.
- 8x8: runs reach six squares, with many more crossings.
- 10x10: runs of up to seven squares across a full page.
- 12x12: runs of up to eight squares, each one missing exactly one digit.
Kakuro difficulty levels
- Easy: the possible digit sets of each clue, checked against the digits already in place, finish the grid.
- Medium: adds placement, finding the one square of a run that can take a digit the run needs.
- Hard: weighs complete fillings of a run and keeps in each square only the digits some filling allows.
Kakuro terms explained
- Clue: the total printed in a black square.
- Run: an unbroken line of white squares, across or down.
- Combination: a set of different digits that reaches a clue, such as 1, 2 and 4 for 7 in three squares.
- Crossing: a white square that belongs to one run across and one run down.
Printing the free kakuro sheets
- Every size has its own page, and the 6x6 and 8x8 sizes add a page with four grids on each sheet.
- Within a page, sheets are ordered from Easy to Hard.
- Each sheet saves as a PDF, SVG or WebP file sized for A4, and a book PDF binds all the sheets of a page.
- No answers are printed here; the Kakuro generator draws new grids of any size and level together with their solutions.
