Kakuro (cross-sums) is an addictive puzzle game from Japan and is often qualified as Sudoku's bigger brother. If you enjoy solving Sudoku puzzles, you will surely love to be challenged by Kakuro. And ... don't be misled by the first impression - Kakuro is much easier than it may seem and involves more logical than mathematical skills.
