Title: Provides hours of intense, enjoyable effort.
Product review: This book has been the source of hours of mind-stretching entertainment for my children and several hours of frustration for me. The puzzles are difficult, yet not impossible and there is nothing better in improving your powers of intense observation. They can be enjoyed by all children approximately eight years of age and older. I highly recommend it.
