How to Play: Kakuro is a crossword with numbers that serve as the clues. The numbers you are given in the black cells represent the sum of that row or column. The goal is to enter digits 1-9 in the white cells to add up to the number stated. You cannot enter any number more than once.

Warning: Kakuro may cause you to forget reality, lose all sense of time, miss your bus stop, and wear out all erasers in a three mile radius. Use with caution!
