Q-ba-maze 2.0 is a unique system of colorful cubes that interlock to form a marble run. The big difference? You can create marble maze sculptures in the form of animals, geometric shapes, or any other design! Configurations are unlimited, allowing for unpredictable action when steel balls travel the various routes. It's a live demonstration of probability, physics, and art, all in one! The starter box includes 36 cubes and 14 marbles. Q-ba-maze 2.0 cubes are not compatible with the original Q-ba-maze cubes. Reengineered joints provide exceptional stability. Smooth cubes slide together with ease. Made with 20% less plastic. MindWare
