The puzzles in this spiral-bound Sudoku book may be tough on the brain but the large print makes them easy on the eyes. Fill in each grid so the numbers 1 through 9 appear only once in every row, column and 3-by-3 box in bold borders. Puzzle difficulty levels range from easy (1 star) to challenging (3 stars). This is the second book in the series.
