Gecko Marble Run Twister Marble Run Expansion Pack - Thames & Kosmos

Add the Twist. Add the Speed. — Gecko Run Twister Marble Run Expansion Pack

The Gecko Run Twister Expansion Pack adds a twisting spiral element to your vertical Gecko Run marble run — sending the marble into a spinning descent before rejoining the main track. The pack attaches to any flat surface using nano adhesive pads (no sticky residue, removable and repositionable cleanly) and includes adapters and track sections to integrate the twister into your existing Gecko Run build. Tracks are made from renewable raw materials and produced in Germany. Ages 8+.

What’s in the Pack

• ✅ 1 twister — the spinning spiral element; the centrepiece of this expansion
• ✅ 4 adapters — for connecting the twister to existing Gecko Run tracks
• ✅ 2 tracks — additional track sections to route marbles into and out of the twister
• ✅ 1 track bridge — for routing tracks over or across each other to increase build complexity
• ✅ 8 nano adhesive pads — attach the tracks to any flat surface; no sticky residue; removable and repositionable without damage
• ✅ Colour illustrated instructions

About Gecko Run

Gecko Run is Thames Kosmos’ vertical marble run system — tracks mount directly onto walls, windows, tiles, or any smooth flat surface using nano adhesive technology, keeping the run off the floor and making it easy to store when not in use. The modular system is designed so every expansion pack integrates with the starter set and with each other, allowing the marble run to grow over time. The twister adds a new movement type — spinning — to complement the loops, snakes, and trampolines available in other expansion packs.

Frequently Asked Questions

Do I need the Starter Set first?

Yes — the Twister Expansion Pack is designed to extend an existing Gecko Run build. You’ll need the Gecko Run Starter Set as the base, which includes the marbles, mounting system, and core track sections. The expansion packs add new elements and movement types on top of the starter foundation.

Will it leave marks on my wall?

No — the nano adhesive pads hold firmly to smooth flat surfaces (walls, windows, tiles, doors) and remove cleanly without sticky residue or surface damage. The pads are repositionable, so you can move and redesign your marble run layout without worrying about marks.

Can it be combined with other Gecko Run expansion packs?

Yes — all Gecko Run expansion packs are compatible with each other and with the starter set. The Twister pairs well with the Loop, Snake, and Trampoline expansions to create a marble run with multiple different movement types across a single build.
