Train Your Brain: Puzzle Book Level 1 Approx 45 One-Colour Illustrations (Mensa Kids) Paperback – Large Print, 17 July 2014

I mean I wouldn't buy for a kid younger than 10 ! i bought this for my 7 year old & she found it very challenging - and it is- its got some good puzzels in though!

Great puzzles to start off young brains. My 6 years old found some of them easy, some more challenging, but enjoyed all.

granddaughter really loves the whole series

Great puzzles

Great!
