Learn through play with a toy that mingles early physics, engineering, and spatial reasoning to stack and interlock an advanced marble maze that keeps everyone guessing, “which way will the marbles go?”

This discovery toy strengthens STEM, physics, basic engineering, strategy and fine-motor skills and is safely made from phthalate-free and BPA-free ABS plastic and the marbles are nickel plated steel balls, not magnets.

Includes:

• 20 single-exit cubes
• 10 bottom-exit cubes
• 10 double-exit cubes
