I enjoy the toughest Sudokus, I do solve them all; when really at a 'dead-end', I rely on "Ariadne's thread", aka 'smart-guessing' (once I have narrowed down dozens of relations). This book drives me to that process more than any other, including more often than with Frank Longo's other good book "Second-Degree Black Belt Sudoku".

Good, difficult puzzles, but I was a little disappointed that the book was smaller than the 2nd Degree Black Belt Sudoku that we purchased earlier. This book only has one puzzle per page instead of two, and I probably wouldn't have bought it had I realized that.

Frank Longo is the only sudoku writter that I will do. This is a great little takealong book. It has a hard cover so you can write without another surface. It has good paper for erasing pencil marks. The puzzles are difficult and incorporate many of the stratagies he has put forth in his instruction book. All in all, a great little book, I only wish it had more puzzles.

I love this book and have all of them from level 6 up. Almost all of these can be solved without any forcing. I enjoyed every minute of this book. I wish there was a level 10, 11, and 12 so the enjoyment could go on. Alas, the search for more truly hard sudoku books continues now that I have done every puzzle in this book twice.

My husband loves puzzles like Sudoku. A few Christmas's ago I gave him one of these as a stocking stuffer. This past year he requested I get him more/next level up. It doesn't take him long to use one of these up, but it's nice and portable.

Great challenging puzzles and easy to take along with you so you can do them while waiting for doctor appointments, etc. Just stick it in your pocket. Wish there were more like this one.

I really like this book, it's difficult but great fun. The puzzles do present a challenge, but they're not impossible to solve.

I spent, I don't even know how many, hours on the first puzzle trying to find that hidden relationship to move forward. Well, there wasn't one. You had to guess a number at some point to continue. In my opinion, that is NOT good Sudoku. They should put that on the book. "Some puzzles require guessing." I don't want to guess. I want straight logic. Otherwise, I could guess the whole puzzle.

Other than that, the puzzles are slightly difficult (depending on your level, of course).

Definitely challenging. Had to go through a lot of other "challenging" books that were all but... This one is difficult enough without making you feel totally inadequate. A few I could only solve by trying combinations with trial and error, and seeing what worked. Perfect size book, with enough room to jot your little number combinations in. Only one I'll buy from now on.

I ordered this as a gift for my mother. it was in great condition. It was smaller than I expected, but the price was accurate
