399 Games, Puzzles & Trivia Challenges Specially Designed to Keep Your Brain Young

I buy a lot of books on Amazon, and 50% of them arrive damaged. Maybe I should learn my lessons and go to an actual bookstore. It looks like a reasonable book, but I will sadly be returning it!

This brain training book for adults is really useful and has a good variety of puzzles to solve to keep your brain active. I particularly like the fact that that it’s is very informative at the start of the book. Plenty to keep you going for a while. Very good value.

This is a large collection of puzzles with a great variety of puzzle types and varying skill levels. Most puzzles and answers seem fairly easy (which give you a sense of accomplishment), however there's always a few in each puzzle that are a little more difficult and make you think a little harder, which is the whole point. I would recommend this book.

I'm in my 60's and bought this book to play the games to help keep my mind sharp. I'm enjoying it.

Ich bin ein richtiger Fan von Logik und Matherätsel. Das Buch ist genau das richtige für mich und meiner Freundin. Wir haben richtige Rätselstunden mit dem Buch.

It is only for people very very femilier with Amiracan culture and its history.
