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.
