Just remember, they are meant to be a challenge. If you think your personality fits even just some of those definitions, try this book. But, by solving these puzzles I have discovered that I am determined, resolute, stubborn, patient, and very thorough. I am not mathematically inclined in real life. Longo gives the puzzle fanatic some honest-to-goodness workouts for your brain. This book is NOT for a beginning Sudoku solver. If I could hold the number possibilities in my memory longer I probably could do these without the "little numbers". I still have to put in my "little numbers" for the puzzles but they really do solve themselves very well from that stage on. I find that if I take my time and pay close attention I can solve these on the first try. Only the most basic solving technique is given. Please do not expect any detailed instructions for Sudoku solving in this book. In the Second Degree Black Belt Sudoku he says: "This book consists of 300 puzzles of super-tough level of difficulty." I had already found that I could believe his word for describing his own puzzles. Inside the book Longo himself describes the Brown Belt as "300 puzzles of hard level of difficulty". While I was in the bookstore I saw the Brown Belt edition and wondered what the difference would be. I loved that book so much that I bought it again last weekend. I have actually come to this book after solving the puzzles in the Second Degree Black Belt Sudoku by Frank Longo. It would be nice if the puzzles were a little larger but I have adapted to what I have been given. Each sheet contains two puzzles on each side. I solve the problem by using a box-cutter and removing four or five pages at a time. I like to have the sheet flat and to be able to move my hand around on the page freely. This is a personal quirk of mine and it may not bother you at all. Paul Stephans has had a long career as a technical author and it shows.Īvoid books by Carol Vorderman, she places too much emphasis on long length claims, which she may well be very good at, but she does not explain the very wide set of additional techniques that can be employed.This book would rate 5 glowing stars from me except.that the format of the book is such that I have to remove the page from the book to be able to solve the puzzle comfortably. It is concise, precise and also uses limited colour to draw attention to the cells featuring in a particular explanation. While he has had over 3,000 crossword puzzles published since 1993, he has been focusing on the sudoku craze for the past several years. This is without any doubt the best book on solving Sudoku. Frank Longo is a freelance puzzle creator living in Hoboken, NJ. What a shame.Ī better book, but with fewer examples, is Mastering Sudoku week by week, by Paul Stephans. However, these multiple puzzle listings are far too small to allow convenient solving since there is not enough room in the very small cell size to write all of the possible candidates. This makes this book the leader in that example class. It describes all of the advanced techniques and for each of these it lists a great number of puzzles that require that particular technique. This is a good book on how to solve Sudoku puzzles.
