{"product_id":"gecko-run-marble-run-challenge-edition","title":"Gecko Run: Marble Run Challenge Edition","description":"\u003cp\u003eExperience competitive marble-run engineering with a compact, surface-friendly set designed for head-to-head challenges. This Challenge Edition includes everything needed for two builders or two teams to race: 32 challenge cards that set timed or part-limited goals (longest, fastest, etc.), two rapid-fire launchers, flexible track elements, and nano pads that attach to most smooth vertical surfaces so doors, windows, and cabinets become part of the course. A 16-page illustrated manual walks players through setup and how each element works, then players draw a challenge card and put creativity and problem-solving to the test. The open-ended challenges promote hands-on engineering, iterative design, motor-skill development, and cooperative or competitive play — perfect for solo practice, classroom activities, or game nights. Ages 8+. \u003c\/p\u003e","brand":"Thames \u0026 Kosmos","offers":[{"title":"Default Title","offer_id":42140697264210,"sku":"550213","price":79.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0286\/1203\/4642\/files\/Screenshot2025-09-05103302.png?v=1757086394","url":"https:\/\/www.amazeumstore.org\/es\/products\/gecko-run-marble-run-challenge-edition","provider":"Scott Family Amazeum Museum Store","version":"1.0","type":"link"}
