Kids and marble run enthusiasts, this KOSMOS Gecko Run Challenge takes marble tracks to exciting new heights - literally! This vertical marble run system uses clever nano pads that stick to any smooth surface like tiles, cupboards, or window panes, allowing you to build spectacular tracks that defy gravity. The set comes with 32 tricky task cards that present fun challenges - whether playing alone, in teams, or competing against others, there's always a new puzzle to solve. The newly developed ball starter and collection container add to the excitement, making each run more engaging. What's really cool is how this system combines with other marble runs - thanks to standardized steel balls, you can extend your existing tracks to create even more elaborate constructions. The tracks are made from renewable raw materials and manufactured in Germany, ensuring quality and environmental responsibility. The free-building aspect encourages creativity and problem-solving skills, while the challenge cards provide structured fun for when you want specific goals. Recommended for ages 8 and up, this marble run develops spatial reasoning, planning skills, and patience in young builders. Your wall space is about to become the most exciting construction zone in the house with this innovative vertical marble run system!
