Kakuro

Kakuro is a popular logic puzzle made with a patterned grid of empty squares. Each empty square must be filled with a number between 1 and 9. Numbers can only be used once in each horizontal or vertical series, and they must add up to the sum shown above each column or to the left of each row. Each puzzle has only one unique solution.

Hitori

My hitori generator still needs work, as it can't yet make puzzles which can be solved with logic alone. I'm working on it. If anyone knows of any free hitori generators, I'd appreciate the info.
