Gecko Run takes classic marble runs to another level with new creative challenges and less restrictive building requirements. This innovative track system uses specially designed flexible rails that require no support structures. Traditional marble runs require many pieces to build height, but with Gecko Run, your doors, windows, cabinets, shelves—virtually any smooth surface—become part of the track, allowing you to build higher with fewer pieces.

Attach the tracks to surfaces with the help of ingenious nano-pads, which work like nanoscopic suction cups, to create a strong, yet temporary, bond. Because the pads contain no adhesive, they can be quickly and easily repositioned many times without damaging adhesives or leaving sticky residue. A simple wipe with a microfiber cloth will keep them ready to use!

The versatile tracks are made from renewable, durable, and sustainably sourced raw materials. Thanks to their wide range of motion and flexibility, you can create hills and jumps, and even curves to generate endless tricks and stunts. No two tracks are alike! Each unique configuration encourages hands-on experimentation, supports problem-solving through trial and error, develops motor skills, and stimulates creativity in both children and adults.

With the Gecko Run: Snake Expansion Pack, you can send your marbles through a maze of tight curves and see how it affects their speed. But be careful: only if you place the snake correctly in your marble run will the marbles make it through!

The Snake Expansion Pack includes over a dozen pieces to complement the Gecko Run starter set, including the Snake stunt, additional marbles and nano-adhesive pads, 2 additional tracks, and more.
