This expertly designed collection is ideal for playing during lunch, on a long commute or anytime at all. This addition to the bestselling Sit & Solve[registered] series offers a clever selection of kakuro, a terrific type of puzzle that combines logical thinking with simple addition. It's perfect for solvers looking to go beyond the usual and stretch their mental muscles a bit more. Little numbers appear all over the grid and it's up to solvers to fill in the rest of the grid with digits that add up to the little numbers. Sudoku is fun, but kakuro is even better!
