Also known as Cross Sums, Kakuro is a mix between a crossword and sudoku puzzle. Unlike a crossword puzzle where the clue is a word or phrase, a Kakuro clue is a number that the corresponding answer cells must add up to. That’s where the sudoku part comes in. Each clue has at least 2 and no more than 9 answer cells. Each answer cell must be a single digit (1-9). Duplicate digits are not allowed within a clue (4 = 1+3, 4 ≠ 2+2).

Each puzzle has a unique solution that can be solved without guesswork.
