Gecko Run Marble Run Starter Set by Thames & Kosmos – Toy of the Year Winner, 63-Piece Vertical Marble Run with Flexible Tracks

Gecko Run: A smarter marble run for curious builders

Gecko Run redefines traditional marble runs by using a patented system of flexible tracks that adhere to smooth surfaces with nano-adhesive pads. No glue, no mess: you can reposition tracks quickly to try new layouts on doors, windows, or shelves. The result is higher, more dynamic routes with fewer pieces.

Designed with sustainability in mind, the tracks are made from renewable raw materials, combining durability with eco-conscious materials. The modular design invites kids and grownups to experiment together, turning playtime into a mini engineering challenge without clutter or long assembly times.

What you can build and how it feels

With Gecko Run’s flexible tracks, you can zip, zag, bounce, and hurdle through vertical and curved paths. Hills, turns, and even corners become part of the track, letting you explore a wide range of tricks and sequences. The system encourages trial-and-error exploration, helping young builders practice problem solving while watching physics in action.

• Higher builds with fewer pieces thanks to surface-bound tracks
• Mess-free setup on doors, windows, shelves, or bookcases
• Quickly repositionable nano-adhesive pads with no sticky residue

Included components and how it works

The Starter Set includes over 60 pieces, such as 12 tracks, 7 marbles, 40 nano-adhesive pads, levers, a funnel, and a 16-page illustrated manual. You get a complete starting point right out of the box, plus the option to expand with additional packs for even more layouts.

• 60+ pieces for versatile configurations
• 40 nano pads for secure, residue-free adhesion
• Levers and a funnel introduce timing and branching challenges

Why families and classrooms love Gecko Run

The open-ended design fosters hands-on experimentation, motor skills development, and creative thinking as you design and test new routes. It pairs well with other expansion packs, inviting ongoing exploration and collaboration between kids and grownups alike. And because the pads are reusable, you can refresh setups without waste or cleanup worries.
