Our game was not balanced from the get go. Take one disc off and the unit would topple over. Huh?? I shaved the plastic on several discs and got it more balanced. Now, one could remove one disc and it wouldn't topple over. Of course this makes set up a pain. No matter, getting the second disc off almost always toppled the unit. This game is unplayable, isn't fun at all, and I wouldn't recommend it to anyone.
I played this game with my brother and now I want to give it to my grandson. It's a "no batteried required" builder of hand-eye coordinations. But most of all, it's just plain FUN!!
