Not very challenging, 16 Jan. 2011
Two complaints about this book;
First, The puzzles are not very challenging. I'm not an expert, but have been doing Sudoku for a few years now. In this book, I fly through the hardest ('Migraine'), hardly having to think about it. The book was a complete waste for me.
Second, there is virtually no margin around the puzzles to jot notes. Since I found them so easy, I didn't need to make notes, but would have been frustrating if I did. I would prefer to have more white space around the puzzles.
