Double Spiral Wooden Marble Circuit – Quadrilla

The Quadrilla Double Spiral Wooden Marble Run is a unique accessory that expands the possibilities of your tracks with a spectacular and educational design. This double spiral is designed to be used on both sides, doubling the fun: on the concave side, the marbles swirl from the edge to the center, while on the convex side, they do the opposite, moving from the center to the edge. This engineering game inspired by Da Vinci's Circles has been praised by media outlets such as The Wall Street Journal as a perfect tool for teaching coding principles. Thanks to its modular structure, it stimulates logical thinking, planning, and STEM (Science, Technology, Engineering, and Mathematics) fundamentals from an early age. Compatible with all Quadrilla sets from Hape, this circuit allows children aged 4 and up to build, experiment, and discover how movement, speed, and gravity work.
