Kakuro Zone (iAd version) is a free version of the KakuroZone game, offering 25,000 different puzzles distributed over five game levels, ranging from easy to very challenging.

Kakuro is related to Sudoku and just as addictive - it is played by entering digits from 1 to 9 into fields in a grid so that they add up to the sum clues given in the puzzle.

With a well thought-out and clean user interface, Kakuro Zone gets you playing right away. Every new game loads instantly (no waiting time!), and the five game levels provide plenty of challenges for both beginners and advanced players.
