You can develop out-of-the-box thinking not only at school, but also in the most seemingly unexpected places: in public transport, standing in line at the store, and even sitting in the “right place”! Why waste time when you can put it to good use? Just take this book with you. In it you will find a lot of fascinating puzzles, thanks to which you will not only exercise your wits, but also learn a lot of new things and have a lot of fun. Do not rush to peep the answers that are located at the end of the publication, try to come to a decision on your own, because this is the whole point. Allow yourself the luxury of…thinking.
