Mastermind: Over 100 Games, Tests, and Puzzles to Unleash Your Inner Genius (Science & Nature)

Fabulous love this item great seller

My nephew throughly enjoy this book for two whole days. He was obsessed for hours both days, and it kept him off the iPad or iPhone which was great! Bought more, other titles like this one from National Geographic for Kids :)

I buy NatGeo books for my grandchildren. Have been doing this since they could look at a book. They now know everything about the planets, what swims under the ocean etc.etc. I won't stop until they are ready for the big guy's NatGeo. They are 8 right now and I see you have some new titles coming in soon I will be back.

Not bad

I ordered this as a christmas present and just opening it up looks like my neighbor will enjoy this book for sure.

My 8 year old loves this! We loved it so much that we bought a stash of these books to use as gifts for kid birthday parties. Perfect for the 8-10 year old range. A lot of fun, with some learning to go along with it.
