Marble Run is one of the most popular collection of ROKR 3D wooden puzzles. This series of puzzles are all gear drive - the most widely used mechanical rotation method. No batteries are needed to allow the marble ball to open an infinite loop on the mechanical city. Isn't it amazing?
We believe it is the coolest 3D wooden puzzle collection that you'll love. In this collection, we offer several wooden marble run models and kits for you to choose. Enjoy your self-assembling process and hope it could give you inspiration while the ball rolling!
