Gecko Run Deluxe Starter Set by Thames & Kosmos – Vertical Marble Run with Flexible Tracks

Gecko Run takes classic marble runs to new heights with a clever system of flexible tracks that stick to smooth surfaces using nano-adhesive pads. No glue, no messy tape—just quick, residue-free bonds you can reposition in moments. This design invites hands-on exploration that can be repeated and refined as you experiment with gravity, momentum, and timing.

Because the tracks are flexible and open-ended, you can transform doors, windows, bookcases, and other smooth surfaces into part of your run. Build higher with fewer pieces, then bend, twist, and turn to create hills, loops, and corners. The ability to connect different configurations encourages kids and grown-ups to tinker together, testing ideas and sharing discoveries.

The Gecko Run Deluxe Starter Set pairs sustainability with play. Tracks are made from renewable raw materials, and the adhesive pads are reusable and gentle on surfaces, so you can wipe them clean with a microfiber cloth and reposition them without residue. The set includes a rich assortment of components: tracks, connectors, marbles, and expansion packs—Loop and Trampoline—plus a bonus funnel and lever, designed to spark a wide range of experiments.

Open-ended play and learning

• Endless configurations: design vertical runs, loops, and jumps across different surfaces.
• Hands-on problem solving: trial-and-error builds help explore cause and effect and develop fine motor skills.
• Observe physics in action: watch gravity, momentum, and timing shape each run.
• Safe, clean setup: nano pads provide a non-permanent bond that wipes clean easily.

What’s in the Deluxe Starter Set

• Over 90 pieces, including all original components plus Loop and Trampoline expansions, and a bonus funnel and lever.
• 16 tracks, 10 marbles, 56 nano-adhesive pads, and more for flexible play.
• 16-page illustrated manual to guide your first runs and explain each element's function.
• Compatibility: expand with other packs like Twister or Snake for broader play.

Experience and feel

Gecko Run feels tactile and inviting: smooth plastic tracks, snug connectors, and the satisfying snap of a successful run. The design invites you to step back, observe, and adjust, turning play into a gentle, engineering-focused activity that suits solo sessions or family collaboration.
