This review is from: Puzzlebook: 100 Puzzle Quizzes (color and interactive!) (Kindle Edition)
I'm a sucker for a good puzzle book, but I've never had an ebook version before. The touchscreen interactivity is an added bonus to the typical paper versions of this genre of book. If you have a Kindle, iPad or iPhone, then you could literally spend hours with these challenging, mind-expanding and fun puzzles. Keeps your mind sharp!
