Also known as: Croco Puzzle, Cross Sums, CrossSam, Kasan Kurosu, Kreuzsummenrätsel, Tashizan Cross, Zahlenschwede

Kakuro originated in the United States in the 1950s under the name of Cross Sums. A logic puzzle, the aim of Kakuro is to complete a grid using digits from 1 to 9, with the digits in each row/column adding up to the clue for that block. It’s similar to Sudoku in the sense that digits cannot be repeated in a row/column.

Kakuro is popular in Japan, where for many years it was the most popular puzzle until the resurgence of Sudoku, also a hugely successful puzzle.
