 More challenging than the First Degree Black Belt book Jul 07, 2006
By Jason Harland
This was the first sudoku book I bought after doing numerous puzzles from newspapers and online. This book lasted me a good 6 months, and was an excellent time killer on bus cummutes to work, during lunch breaks, during a hospital stay, while waiting for food in restaurant, and anywhere else the sudoku mood struck me.
The puzzles can not simply be solved by inspection. You must fill in all of the cells with number possibilities. Some of the puzzles can easily be solved by single candidate from there, while others require you to use candidate reduction strategies.
A good book to start with for anyone serious about getting into sudokus.

This would rate 5 glowing stars from me except....... Aug 15, 2008
By J. Lesley

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. This is a personal quirk of mine and it may not bother you at all. I like to have the sheet flat and to be able to move my hand around on the page freely. I solve the problem by using a box-cutter and removing four or five pages at a time. Each sheet contains two puzzles on each side. It would be nice if the puzzles were a little larger but I have adapted to what I have been given.
I have actually come to this book after solving the puzzles in the Second Degree Black Belt Sudoku by Frank Longo. I loved that book so much that I bought it again last weekend. While I was in the bookstore I saw the Brown Belt edition and wondered what the difference would be. Inside the book Longo himself describes the Brown Belt as "300 puzzles of hard level of difficulty". 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. I decided to give the Brown Belt a try. Please do not expect any detailed instructions for Sudoku solving in this book. Only the most basic solving technique is given.
Once again, I just love these puzzles. They are "hard" but not impossible. I find that if I take my time and pay close attention I can solve these on the first try. I still have to put in my "little numbers" for the puzzles but they really do solve themselves very well from that stage on. If I could hold the number possibilities in my memory longer I probably could do these without the "little numbers".
This book is NOT for a beginning Sudoku solver. Mr. Longo gives the puzzle fanatic some honest-to-goodness workouts for your brain. I am not mathematically inclined in real life. But, by solving these puzzles I have discovered that I am determined, resolute, stubborn, patient, and very thorough. If you think your personality fits even just some of those definitions, try this book. Just remember, they are meant to be a challenge. Don't expect anything to come easily.

 to hard Sep 29, 2009
By wizard
Original brown belt sudoku was great, however 2nd degree is way more difficult than I was expecting. For those of you who are looking for something along the lines of the original, I would suggest second degree green belt.

 Nice challenge. Lots of fun. Not annoyingly easy. May 06, 2008
By D. Cepulis
The "Second-degree" versions of the sudoku books seem to be the actual challenging ones, whether brown or black belt. Frank Longo has delivered in this book 300 challenging, yet deterministic Sudoku puzzles for the avid sudoku fan. No guessing and "playing out" necessary if you just look long enough.
I would compare these to the "Evil" level on websudoku(dot)com. Most experienced Sudoku fanatics should be able to knock one of these puzzles out in 10 - 15 mins, with exceptions.

 Ridiculously difficult, and not in a good way. May 05, 2007
By Felix Madera
"Sudoku Addict"
Don't waste your time buying this book. It's nowhere near as good as the Brown Belt first version. You should be able to make a logical inference (based upon the numbers already in the squares) what numbers belong where, but that's not possible with this one. You have to basically play out different scenarios (such as "ok, if the two was here, how would they play out?").
If you want that in a Black Belt level, great. For Brown Belt, that's ridiculous. Don't waste your money. I told a friend this in advance of her getting the book, and now she wishes she had listened to me. Don't say I didn't warn you.
