Puzzle Book is is just as Amazon stated will purchase more from Amazon in the future. Thank you for offering a chance to purchase items thru the mail for those of us who cannot get around very well.

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.

... at least, not according to Will Shortz's standards. Will Shortz is the editor of the NY Times crossword puzzle and has several Sudoku books to his name. From what I've seen, his books always include a range from "Light 'n Easy" to "Beware! Very Challenging". So far, I've only purchased his books, but since only about 20% of them are really tough, I thought it would be nice to get a book with nothing but the brain-squeezers. Unfortunately, the Sudoku puzzles here all fall into the "Light 'n Easy" category.

A rule of thumb for how difficult a Sudoku will be is how many digits the puzzle starts out with. A really hard one may have 17 or 18. The ones in this book, by contrast, have 25+.

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.).

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!
