This IQpuzzler is very addictive for all those who want to train their brain. This brainteaser has 101 challenges in 2D and 3D and is suitable from age 6+. I already bought this game several times to give as a present and now people keep asking me where to get it. If you live in Belgium, you can get them in De Banier. This one will be packed to go on holiday too! :)
