Customer Reviews

One of Best Sudoku Books
This is one of the best advanced sudoku books available. There are no puzzles at beginning or intermediate level. The paper is good quality and firm and takes pencil marks or ballpoint and erasures easily. The book is spiral bound and opens flat and easily. There are 242 puzzles of the highest degree of difficulty, two per page. The solutions at the back are all correct. If you are an advanced solver, this is an excellent book for you. It is not easy to find good, advanced sudoku books.

I love the pain!
As someone who searches for seriously difficult sudoku, I love this book. The puzzles are all very hard, but still require a variety of solving methods, some of which I find approachable, and others of which are truly painful, at least for me. I agree with another reviewer that it would be nice to have "speaking" solutions, that is, solutions that explain how the puzzle was solved, but solving methods vary so much by player that this is probably only a dream. There are truly no linear solution methods, which is what makes sudoku so attractive.

Compared to the many other books that claim to offer very hard sudoku, this one stands way out as telling it like it is.

I criticised the "Mensa Guide" book for its fragile binding and tiny grids, so I have to award big points for the spiral binding and large grids of this book.

Tough puzzles!
Mostly very tough puzzles, that (like book #3) lived up to the books' name. We're very happy to have bought #3 and #4.

Question, does Mr Longo know there are duplicate puzzles in #4?
#69 is duplicated in 75, 82, 95, 99, 119, and 127.
#134 is duplicated in 202.
