is a challenging logic-based puzzle game. It combines elements of Sudoku with the strategy of a crossword puzzle. Except the crossword clues are the total sum of all of the values in each vertical or horizontal section. The goal of the game is to fill each cell with a number from 1 through 9. However, each continuous vertical or horizontal line cannot have more than one instance of any number. The puzzle is solved when all of the cells have been correctly filled. Each time you play, you are faced with a completely new challenge - iSS Kakuro has over 1 million puzzles, so no two games are ever the same!
