Kakuro is a number puzzle with the feel of a crossword: fill each run of white squares with digits 1 to 9 so they add up to the clue, using no digit twice within a run. The Sum of All Fears contains 100 hard grids, the toughest set in the series, for solvers who want to work. The book opens with a plain-language how-to-play guide, and every grid is set in large print with room to write.

How it works

Files are available to download right after purchase. Print the whole book or only the pages you want, as many times as you like for personal or single-facility use. Print at 100 percent scale (no fit-to-page) so the grids stay full size. Standard black-and-white printing is all that is needed.

Please note

This is a digital download. No physical book will be shipped. Because the files are delivered instantly, returns and exchanges are not available. Files are for personal use or use within one activity program; resale or redistribution of the files is not permitted.
