One of the Better Sudoku Books Out There
As a lot of people have, I have become a big fan of Sudoku lately. A problem with a lot of books out there for Sudoku is that they can have way too many easy puzzles for the more advanced Sudoku user or they don't quite follow the rules I find are important (an earlier book I owned required guessing to get to solve a puzzle in the more advanced stages, or they don't start out with symmetric patterns, which the more traditional sudoku start with).

This book is fantastic in that the puzzles start off challenging (this is not a beginners book). They incorporate more advanced techniques that one doesn't often find in books while not putting in techniques that are so advanced one would need a computer to use (This is a flaw in other books as well).

The only drawback. I've seen in the book is that some of the terminology is inconsistent with a lot of the seemingly official terminology seen on internet forums and puzzles. I'll also admit that I am not a huge fan of some of the variations presented in the book. They aren't necessarily bad, but I think it would have been neater to throw in a couple of Killer Sudoku or Samurai Sudoku puzzles to show some challenging variations.

With this book I'm no longer a Sudoku dummy
I recently acquired a nice computer-aided Sukoku solver called UniSudoku for Macintosh computers and decided that since the drudgery of determining what options remained for each square were handled nicely by this solver, that I could concentrate on the strategy of solving Sudoku puzzles without guessing. I started to look for strategies published online and got hopelessly confused with the multitude of names for these various strategies.

I then bought this book. The strategies it offers for really hard Sudokus (especially x-y (conjugate pair) chains, x-y chains, and unique rectangles) have been fantastic for solving every level of difficulty of Sudoku puzzles I have encountered. As a previous Amazon reviewer has noted, these strategies are simply explained with examples that allow you to solve any puzzle that is presented to you. I highly recommend this book.

Advanced Sudoku Made "Simple"
This book contains not only difficult Sudoku puzzles, but also a good description of strategies for solving them. These strategies include: Naked pairs, naked triplets, hidden pairs, hidden triplets, intersection removal, the X-wing, swordfish, various chains, etc. Although many of these strategies can also be found for free on the internet, the clarity of the explanations in this book, in my opinion, alone make it worth having.

A series of conventional advanced sudoku puzzles is provided, and answers are given in the back. Each puzzle is 3.25 inch by 3.25 inch (8.3 cm by 8.3 cm) in size, making it conveniently large enough to pencil-in the possibilities for each square.

This book also includes unconventional sudoku-based puzzles and their solutions. This encompasses sudoku jigsaw puzzles, killer puzzles, target puzzles, and 12 by 12 (instead of the conventional 9 by 9) sudoku puzzles.
