Free online kakuro puzzles



Kakuro is like a crossword puzzle with numbers. Each "word" must add up to the number provided in the clue above it or to the left. Words can only use the numbers 1 through 9, and a given number can only be used once in a word. Every kakuro puzzle has one and only solution, and can be solved through logic alone.


Kakuro Hint: Start with clues that only have one valid combination. For example, 3 in 2 must be 1 and 2, and 23 in 3 must be 6, 8, and 9.

Kakuro Tutorial -- Challenging

27 in 6 has a limited number of remaining valid permutations. With the first two cells being 2 and 1, 3 and 1, or 3 in 2, we know that the remaining cells will be limited to 5, 6, 7, 8, and 9. The right-most cell is part of 12 in 4, and 5 and 6 are the only valid values for that. Given that, the remaining two cells are limited to 7, 8, and 9.
