A unique building system of colorful cubes that interlock to form a marble run. Configurations are unlimited, allowing for unpredictable action when steel marbles travel the various routes. Get creative and build maze sculptures in the form of animals, geometric shapes, or abstract designs!
Add height and marble madness to your marble run structures. Marbles clatter, teeter, bounce, and leap through cascade stilts and marble runs.
Includes 2 cascade stilts and 40 steel marbles.
