Kakuro (also known as "Cross Sums", "Kakro") is a Logic puzzle, a mathematical equivalent of crosswords.

A number in the top right corner relates to an "across" clue and one in the bottom left a "down" clue.
Some black cells contain a diagonal slash from top left to bottom right with numbers in them, called "the clues".
The puzzle consists of a playing area of filled and empty cells similar to a crossword puzzle.
