Very challenging puzzles - worth every penny Jun 07, 2009
These are the most challenging puzzles I have seen. Each require multiple advanced/diabolical rules in order to solve.
The book is spiral bound, so you can easily rip out the solutions and throw them away. Who cares about solutions. There are dozens of Internet sites that can provide solutions.

Challenging Feb 24, 2009
I bought the puzzle book for my mom who had complained that another book she purchased that was rated 'difficult' was too easy. Well this book was definitely challenging for her. She also liked the fact that it was spiral bound so that she can turn the pages all the way over.

Great book for expert level players. Dec 24, 2008
This series is the best sudoku series available for intermediate and advanced players. The level 4 is close to level 3, but there are more puzzles with difficult linked chains and other advanced techniques. If you have trouble with these you need to buy the Mensa guide to solving sudoku.

Very difficult book Jul 17, 2008
I enjoy this book, but strongly suggest not buying it unless you have exhausted/outgrown the other Sudoku books. This is the hardest book I have found by far. I didn't work through levels 1 - 3 (probably should have). The next hardest book I have is "Even Higher Sudoku". The latter might be good to try before moving on to this book.

Best tough Sudoku book Apr 17, 2008
This is the only Sudoku book I've found where I can't do over half of the puzzles without notes. So if you want to tax your brain a bit and know about Gordian Polygons then this is the sudoku book to buy. Makes the "black belt" and "ultimate ninja" books look easy by comparison. Still all logic and no guessing required.
