Great Building Toy
Posted 6/3/2009 by Amy Carlson
My 9 yr old son just loved building this contraption. I loved working with him on it. He was very motivated to see this machine run so he kept after the construction of it. The pieces are well constructed and come together nicely, he never had trouble manipulating the pieces on his own. I would say that it would have been difficult for him to build this completely on his own but I had a great time working with him on it.
I purchased the Marble Mania Genius for my 10 year old son who loved making it and then in turn watching it work. It was a bit difficult in some parts for him to place the pieces but the challenge was worth it.
