I bought this for my eleven year old brother for Christmas. He already had the Nature Brain Box and being a huge Horrible Histories fan, I didn't think twice before buying this edition.
Although other Brain Boxes can be a little young for that age group, the HH Box was perfect for him - and for the rest of us! We've played again and again, learning all sorts of interesting facts.
I would certainly recommend this to anyone thinking about buying it for your very own Horrible Histories fan - it's written with the same humour as the books and manages, in a very HH way, to impart knowledge without it seeming like you are learning.
