Sudoku Puzzle Book for Adults: 156 Easy to Hard Puzzles Volume I

Verified Customer Review

"Each book contains about 400 games, over two levels of hardness (choose between easy & medium or medium & hard) and comes in a large format (bigger than A4 size; perhaps foolscap?) that requires some strength to hold (I am 75 and have arthritis).The grid squares are big enough for you to write the various possible solution options in them, until the real solution becomes obvious.Occasionally a game has multiple final solutions... which Sudoku aficionados will find frustrating."
