Title: Must have been a mail order black belt...
Review: I have been only doing Sudoku puzzles for a few months and I thought that I was up for a little challenge but this book was definitely not it. I rated the puzzles in this book at a low medium or high easy level. It did not take no more than ten minutes per puzzle (for me anyway). After completing the first boring hundred puzzles(?), I dropped it off at my kid's day care. I figure maybe they might find the book a little more challenging. Besides, they can always color the squares or connect the dots :)
