Review on Lightweight Educational Balancing Gupgi Building by Cody Bowie

I thought you could try balancing at different angles carved into the wooden blocks but you can only on the flat surface of the balance side. We live on 3 acres of rock and I wanted to practice building a cairn: an artificial heap (or stack) of rocks. You see these steep stacks on the footpaths. All I can do is fold them flat side so it's not what I thought but that's my problem as I didn't look closely enough. This product did what was advertised looking back on their website.
