This large-print 8.5" x 11" book is great for those who love large-print font for easy visibility. There are two puzzles on each page and the solutions are on the following page in the same size. Two big puzzles on each page give you plenty of space to note candidates and sturdy paper holds up well to erasing. Large inside margins make it easier to solve the puzzles when you fold or tear out the pages. Large print on white paper is very easy to read (even in dim light). The puzzles are for beginners who are learning how to play Sudoku. Use the sample on the back cover or the look inside feature to judge if the level is right for you. "Older adults who regularly do Sudoku or crosswords have sharper brains that are 10 YEARS younger," reports the Mail Online.
