Name: Kakuro Game Computer
Object: Cross-sums-puzzle - A logic puzzle with arithmetic, addictive brain teaser. Kakuro Puzzles resemble cross-words with numbers. You have 'across' and 'down' clues, but instead of filling in letters, you must use the number 1-9. The game is to fill all the blank squares in the grid with only the number 1-9 so that the numbers you enter add up to the corresponding clues. No number can be duplicate in a entry.
