This review is from: Impossible Su Doku (Paperback)

Seems like all the books claim to be impossible and I bought the "Mensa" book for my wife and she just laughed at it. With this book, you don't have to skip to the back to get to the good ones. From puzzle one we were happy and the only let down is knowing that when you finish this book, you may be out of luck on finding one to compare. As others have mentioned at first you might need to make one guess to solve the puzzles.

This review is from: Impossible Su Doku (Paperback)

Most sudoku books have a lot of very easy and boring puzzles in them. This book is uniformly strong. It's not impossible at all. I never had much trouble solving any of the puzzles, but they are all pretty challenging. A typical puzzle in this book required me to take one guess, and be ready to erase everything after the guess, if necessary, and go back and follow the other route. This book is exactly what it claims to be, if you change the word "impossible" to "interesting". It's a lot better than most other sudoku books out there because they are just too damn easy.
