MacKakuro, a follow up to the popular MacSudoku, generates and allows you to solve Kakuro (otherwise known as Cross Sums) puzzles, which are deceptively simple and addictive logical puzzles in a similar style to Sudoku.
MacKakuro features 6 different sizes of high-quality, symmetrical puzzles, a puzzle timer, statistics, and an easy-to-use, intuitive interface.
GAZMAN Wow, I think my brain just melted. It took me and my partner, working together, ages to get started but we finally finished our first Kakuro puzzle. Definitely gets the old noggin' going. For a 1.0 release it feels quite polished and the developer has stated he will be adding new features. (Version 1.0)
