Kakuro is played on a grid of filled and barred cells, black and white respectively. Apart from the top row and leftmost column which are entirely black, the grid is divided into entries - lines of white cells - by the black cells. The black cells contain a diagonal slash from upper-left to lower- right and a number in one or both halves. These numbers are called clues .This book contains 228 Kakuro puzzles from small and easy up to large 17x17 puzzles.
