This book has shown me how to do suduko--clear, easy to understand explanation, try it if you're having trouble getting started with this puzzle.

This book helped me figure out Sudoku, I'm a beginner. Looking forward to finishing more puzzles and getting to the next level. I'm addicted!

This book offers more challenging puzzles than your average "easy" books. It was great for the addicted!

I bought (and eventually burned) another Sudoku book which had very inaccurately grouped puzzles. It's very first puzzle, supposedly "gentle", was in fact pretty difficult. I got very annoyed with the book.

By contrast, this Will Shortz book seems to have done a good job of ranking the puzzles. It's a very simple book. Well done. I've gotten hours of enjoyment from solving theses puzzles.

This is a nice little book of puzzles. It is as it says it is, easy. Most of the entries have 30+ squares of the 81 with given numbers, so that filling out the remaining squares is a matter of simple logic. Although nothing but the elements of the game are provided as instructions, the ease with which the puzzles are completed helps the beginner learn some of the beginning logic behind doing them. I find I enjoy discovering the "tricks" of finishing these puzzles more satisfying than I would being told before hand what they are. Certainly I learn them more thoroughly by this method, because I have to intuit them; I actually have to understand the "why" behind the manuver. In my opinion this type of learning is inherently helpful in other tasks as well; that it is to say, transferable to ones life settings in other ways--although I have to admit I couldn't tell you specifically how or why. I think getting school age children involved in doing these types of puzzles would be a good idea, since it would help them learn the principles of logical thinking without the pain of word problems.
