Block-N-Roll(TM) is a wonderful product that enables children to build their own marble runs. The possibilities are endless! All Block N Roll(TM) pieces slide securely together at each side. Use the "dimples" for supporting your marble run. If you run out of supports, pull out those DuploŽ blocks because they fit too!
Block N Roll(TM) is the best marble run product that Superdairyboy has been able to find. We like it because of the creativity that building with it it sparks. It has won numerous awards, such as the Parent's Choice Award and Toy of the Year Award.
