My two girls, 6 and 2.5, both enjoy this. Obviously the younger one doesn't catch on much and builds a pretty straight tower but the 6 year old enjoys trying to create new masterpieces.One night, I decided to surprise my oldest and do my best to recreate the picture/example in the pamphlet that uses all the pieces (she had been trying to make the biggest one possible) I ended up on the floor playing with this thing for MUCH longer than I care to admit haha.The pamphlet/example book is less than stellar, there's whole sections of the run that you can't really see in the picture, so you just kind of guess - there's also only a few examples, which stinks if you have a kid who really likes to recreate.We had originally purchased one from a different store but it seemed flimsy and didn't stay together very well. I searched Amazon and found this one, it cost a few dollars more and came with a significant amount of additional pieces. We boxed up the first one, returned that and ordered this one. Some of the pieces don't stay together the best but it's not a huge deal at all.We really like it, hours of fun for kids (and adults) of all ages.
