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: Not sure what a number is yet? Fill in its remaining possible values -- the cell will automatically resize to accommodate.
