We got this and our 3 year old and 5 year old love it. There are two different levels of play- one with the shapes and another without (so you place the shapes on your own to make the larger shape). Both boys feel challenged and enjoy both levels. I think level 2 can work for much older children because even I have to work through figuring out the shapes spatially. Also, the shapes are magnetic, so can be a great toy on the road!All in all, a highly recommended educational toy for many ages- we haven't gotten the adult version of tangoes yet, but plan to!
