It also teaches a child how to follow instructions and ultimately, their own imagination. I’m a senior and my grandson is 11. I recommend purchasing the large starter kit first, then decide on these extensions. ### ⭐⭐⭐⭐⭐ 12yr old son loves these! *by T***S on April 5, 2024* My son loves these! Secretly, so do I. We work together and build the most complicated tracks we can come up with and then race marbles against each other. Great times! ### ⭐⭐⭐⭐⭐ Awesome expansion pack *by D***S on December 4, 2023* Our 10 year old son loves these additions to his Gravitrax kit. Guaranteed to keep kids busy! ## Frequently Bought Together - Ravensburger GraviTrax Bridges Expansion Set - Innovative Marble Run | STEM Toy for Age 8 and Up | Extension for 2019 Toy of The Year Finalist GraviTrax | ASIN 26169 - Ravensburger GraviTrax PRO Turntable Accessory - Innovative Marble Run & STEM Toy | Encourages Creativity and Science Play | Compatible with All GraviTrax Systems | Ideal for Age 8 & Up --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/189823392-ravensburgergravitrax-bridges-expansion-set-innovative-marble-run-stem-toy-age](https://www.desertcart.sn/products/189823392-ravensburgergravitrax-bridges-expansion-set-innovative-marble-run-stem-toy-age) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-07-07*
