The GraviTrax Junior Extension Multi-Routes is an advanced geometry expansion pack designed to bring the excitement of track division, intersections, and clever branching paths to your child’s marble run creations. Custom-tailored for young builders aged three to seven, this thirty-six-piece set focuses entirely on unpredictable navigation, featuring mechanical track switches that redirect marbles, three-in-one converters that split or merge lanes, and four-way crossings where pathways intersect. It even includes specialized tunnel curves with integrated roofs to keep fast-moving marbles securely on track around sharp bends. Every component is crafted from a durable, eco-friendly wood bioplastic blend that feels great in small hands, offering a safe and sensory construction experience. By transforming single-track lines into winding, multi-branch networks, this expansion pack acts as a fantastic, electronic-free tool for developing spatial thinking and early problem-solving skills as preschoolers learn to map out complex railway journeys.
*for a complete play experience, Gravitrax Junior Extensions are to be used with Gravitrax Junior Starter Sets, not as stand-alone items.
