Rokr Parallel World 2-in-1 3D Wooden Marble Run builds into two futuristic miniature city blocks where marbles drop through the streets, ride a lift back up and loop again.

Why it is listed here

Rather than a single tower, this set pairs two themed city models with roughly 410 cm of combined track, and the listing says the lift can link up with other themed models for longer runs. Hip-Hop Street runs on USB-C, so its lift and lights keep marbles looping without any cranking, and a touch switch flips between two modes. Infrared-triggered light effects and a mirrored light tunnel make it as much a lit display as a marble run.

What the build involves

The listing does not give a piece count, finished size or build time, so check those on the product page before planning shelf space. Keep a USB-C power source within reach of where it will sit. Use the guide lines printed on the parts to help with alignment, and run a marble through each city before joining the two.
