200 Difficult Sudoku Puzzles [Paperback]

Peter Greene (Author)

Book Description

Publication Date: July 2005

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've 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 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 One of the good sudoku books, August 2, 2005

These are difficult puzzles! Given numbers range from 20-28, with most puzzles around 24-25. They are not insanely difficult, like puzzles with under 20 given numbers that can take hours to figure out, but they are difficult enough to keep you occupied for a long time...

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

I liked this book, the levels are always relative and I don't think these are supposed to be the hardest puzzles, which suits me fine. I think it would be Easy, Medium, Difficult, Very hard, Fiendish or something like that.

There are actually a limited possible puzzles with only 17 numbers, so when you get down to that few starting numbers it literally can't get any harder. With that in mind, puzzles with 25 starting numbers was exactly what I expected after reading the description of this book.

They don't take an hour to solve though, probably more like 15-20 minutes for most people - but on the other hand the puzzles that first appeared in the newspapers were really simple and this book was written in reponse to that about a year ago. Nowadays people have gotten a lot better at solving the puzzles and so the puzzles in the newspapers are now significantly harder.

According to the last page, there will be a book out soon with REALLY hard puzzles, 18 starting numbers and so on - I'll be waiting for that one! All in all, it's a good book, but not for hardcore sudoku solvers, if that fits your profile I'd recommend the 100 Samurai Sudoku Puzzles instead.

5.0 out of 5 stars From the Board Games Editor at BellaOnline.com, December 11, 2005

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

This is a great sudoku book as far as "bang for your buck" goes, especially for more advanced sudoku-ers, who may find themselves completely skipping the "easy" or "medium" puzzles in mixed-level sudoku books. The puzzles here aren't impossible, but they are relatively tough, which is nice! Because of the degree of difficulty, this book will take most puzzlers quite a while to work all the way through, again making it good bang for your buck.

From what I understand, all mistakes have been fixed and the book is now in perfect puzzle condition, just make sure you get the second edition (which you will if you buy it at Amazon.... if you pick it up at a bookstore, double-check.).
