What is KAKURO?

KAKURO is a fun new puzzle combining logic and simple addition. Although its rules are simple, completing a KAKURO puzzle can be quite a challenge. The object of KAKURO is to place a number from 1 to 9 in every available square of the game board, where the numbers in each horizontal or vertical row when added together must equal the sum provided in the hint squares. A number displayed in the top half of a hint square is the sum of the squares to the right. A number displayed in the bottom half of a hint square is the sum of the squares below it. Hint squares may appear anywhere within a puzzle and may contain two sums. Note: No sum can contain a duplicate number. For example, to total 8 you can enter 7 and 1, 6 and 2, or 5 and 3, but you cannot enter 4 and 4.
