Even more challenging than sudoku, kakuro has become a worldwide craze. Your goal is: to figure out the numbers from 1 to 9 to put in the squares to match the sums given in the black triangle in each direction (horizontal or vertical). This combination of sudoku with the added mathematical challenge will appeal to an even broader range of puzzlers, and there is a page of Unique Sums included in the book to help you get started on the road to becoming a kakuro expert. With over 50 puzzles to keep you busy at lunch, on a tea break or whilst travelling, you will find it a struggle to put the book down, especially as it's so conveniently sized...!
