What's kakuro? It's similar to a crosswordexcept that instead of letters, you use numbers. And that adds up to a great new challenge for solvers. The clue consists of a small white number in a black box next to the empty spaces in the grid. The sum of the digits makes up the answer...and no digit can appear more than once. So imagine that the black square contains the number "7" and there are three boxes to fill: the answer could be 421, 412, 241, 214, 124, or 142, since 4 + 2 + 1 = 7. Each puzzle contains an outlined area that's a good place to start: the solution to that set is on the last page of the book.
