How to Play Kakuro

Kakuro is a popular game similar to sudoku in some ways. But is also suitably different. The key question: "How do you play Kakuro?", well here are the rules of kakuro.

The answer:

• The kakuro grid, unlike in sudoku, can be of any size. It has rows and columns, and dark cells like in a crossword. And, just like in a crossword, some of the dark cells will contain numbers. Some cells will contain two numbers.
• However, in a crossword the numbers reference clues. In a kakuro, the numbers are all you get! They denote the total of the digits in the row or column referenced by the number.
• Within each collection of cells - called a run - any of the numbers 1 to 9 may be used but, like sudoku, each number may only be used once.
