Grand Master Sudoku 1: The Crosswords Without Words―100 Logic Puzzles from Easy to Fiendish

I was a little bit thrown off by the title of this book, when I picked it up I assumed that it would be mostly very difficult sudoku puzzles. Actually, it's a variety of levels, which is totally fine by me. I enjoy more difficult puzzles when I have time to sit down and work through the whole thing (sometimes 2 or 3 times, if I mess it up), and I enjoy easier puzzles for coffee breaks and other times when I only have 10 or 15 minutes.These are hand-developed Sudoku, and they actually do feel a little bit different to work out than computer-generated ones. In any case, this is a great collection.

This book only has 100 puzzles, and for the $8.95 price, it's just not worth it. The puzzles are all levels, not just the more difficult as the title implies. You can get twice the number of puzzles (100 difficult and 100 very challenging)for $6.95 from "Let's Play Sudoku - Over the Edge" by Will Shortz. If you want simpler puzzles, there are 2 easier books of 200 puzzles each in the Will Shortz series, both for $6.95 each as well. I've learned that when a book item description like Grand Master Su Doku doesn't list the number of pages or puzzles, that's a red flag that it's not a good value. If it was a good value, they would list it as a selling point!
