Negative Positive
Title: WAY too easy
Review: Apparently ANYONE can get a black belt if this book is any indication. The 21st puzzle I solved completely by inspection, didn't write ANY number possibilities in at all, which is totally unacceptable for an allegedly hard level sudoku book. If you enjoy challenging sudoku puzzles skip over this book. The Second Degree Brown Belt book was more challenging, though by far my favorite Sudoku book to date is "Sudoku Genius" by Tom Sheldon ISBN 0-452-28750-2.
