Fantastic product. Simple allowing kids to be creative. 200 set might be more useful.

Fantastic toy for the creation and construction. My son is 7 and is obsessed with dominoes, this is great as it adds another dimension to his games. He hasnt put them down yet.

I was surprised, even after reading all the reviews, when I opened the box & found nothing but a slim booklet, 2 ping-pong balls & a pile of tiny planks of wood. I spent just under $30 for 50 tiny planks of wood??? I was disappointed. BUT, after experimenting w/ them my six year old, I can see past the simplicity—the value comes in watching what she does with them. Nothing could be more open ended than a pile of wood—the booklet got us started, but we felt free to go wherever we wanted from there. There’s nothing but gravity to make them stick together, so dexterity, patience, & logic were all required. Every time our structures fell over, which was frequent, we’d laugh & say “We must rebuild!” and start over. I was really impressed with her resilience. I do think $30 is a lot of money for something so simple, even with the pieces being so stackable, AND all the other reviews are 100% correct—50 planks is just enough to start your addiction, not nearly enough to do much of anything with. Especially if you have more than one child. Do yourself a favor & just spring for the 200. That said I really do recommend this as a great toy & think it would span a great range of ages. My six year old still needs my help for the moment, but probably won’t for too much longer.

Haven't opened it yet.

This is the second one we’ve bought. Easy for most ages. Kids need a bit of patience at first, but then they start to create on their own. Second box is because there aren’t quite enough blocks for the bigger longer designs.
