200 Difficult Sudoku Puzzles [Paperback]

Peter Greene (Author)

Book Description

Publication Date: October 10, 2005

Sudoku is the number-placing puzzle that is spreading across the world. The rules are simple, you do not need to know any mathematics, all you need is logic. The puzzles in this book do not require any guessing. They can, and should, be solved by logic steps. This book contains 200 difficult Sudoku puzzles, including solutions and clues. All of the puzzles in this book are made by hand and carefully tested to make sure they are difficult but not impossibly so. You should be able to solve one of the puzzles in under 30 minutes. That means this book can keep you occupied for up to 100 hours! The book also includes a few examples on how to solve Sudoku puzzles to get you started in case you have bought this book without ever having solved a Sudoku before. If that is the case, the clues may also be of help. However, this book is intended for the reasonably experienced Sudoku player.

Editorial Reviews

From the Publisher

This second edition contains identical puzzles to the first, but some minor corrections have been made to improve the quality of the book. Please enjoy!

From the Author

I wrote this book because I found most Sudoku books had too many easy puzzles in them and too few that were any real challenge. I hope you will find it useful on long flights, the beach or the commuter train.

5.0 out of 5 stars Many difficult puzzles, December 1, 2005

This review is from: 200 Difficult Sudoku Puzzles (Paperback)

This book contains a LOT of puzzles, and instead of half of them being easy or medium, they are all difficult. Ofcourse, difficult is a relative term, but if you've only solved easy puzzles before, these may take an hour or two. The typo mentioned below must have been fixed, because I didn't find any. It's a very good book really, and it lasts forever!

1.0 out of 5 stars Misleading title, September 13, 2007

This review is from: 200 Difficult Sudoku Puzzles (Paperback)

I purchase this book because the title says 'Difficult'. I have work through many Sudoku books, and was looking for books containing only difficult puzzles - like many veteran Sudoku fans. I was happy when I received the nicely printed one with 200 'difficult' puzzles. I immediately started with the last puzzle to see how difficult they were, and to my dismay I solved it in minutes. The same went the other last few puzzles. I was able to finish them with a few written notes.

Now I have retitled this book '200 Easy Sudoku Puzzles' give away to beginners.

This review is from: 200 Difficult Sudoku Puzzles (Paperback)

These puzzles may be difficult if you are just starting sudoku, but if you have any experience, these are all pretty easy. They are definitely NOT difficult puzzles. I am solving them on an average of 5 minutes each, with no hesitation as I put in every number. Second edition, with orange cover, has same easy puzzles. This book is not a challenge for any experienced sudoku fan.
