Kakuro Kakuro or Kakkuro (Japanese: カックロ ) is a kind of logic puzzle that is often referred to as a mathematical transliteration of the crossword. Kakuro puzzles are regular features in many math-and-logic puzzle publications across the world. In 1966, Canadian Jacob E. Funk, an employee of Dell Magazines, came up with the original English name "Cross Sums" and other names such as "Cross Addition" have also been used, but the Japanese name "Kakuro," abbreviation of Japanese "kasan kurosu" (加算クロス, addition cross), seems to have gained general acceptance and the puzzles appear to be titled this way now in most publications. The popularity of Kakuro in Japan is immense, second only to Sudoku among Nikoli's famed logic-puzzle offerings.
