Puzzle Book What in the World: Brain-tickling quizzes, sudokus, crosswords and wordsearches (National Geographic Kids) Paperback – 22 February 2018

Best book for kids to improve their GK.

Never disappointed by National Geographic books. The children love them.

This book is great i bought it for my 12 year old son and I wish they did an adult version.The pictures are bright and clear and the puzzles are varied and good fun .It combines learning in a non dominant fun way !

Great puzzles and my daughter learned a lot while being home schooled. Really got her interested in geography and different cultures. Fun puzzles and lots to do.

Full of interesting facts and fun puzzles to keep my 11 year old occupied!

Good, but quickly completed by 7 year old. Great for something to keep youngsters busy on holiday or for a rainy day.
