Kakuro (also known as Cross Sums) is a mathematical logic puzzle. The puzzle consists of a playing area of filled and empty cells similar to a crossword puzzle. Some black cells contain a diagonal slash from top left to bottom right with numbers in them, called “clues”. A number
in the top right corner relates to an “across” clue and one in the bottom left a “down” clue.
The object of a Kakuro is to insert digits from 1 to 9 into the white cells to total the value of the clue associated with it.
