The Marble Run 3D Puzzle combines engineering, creativity, and fantasy-inspired design in one unforgettable building experience. The ROKR Alchemy City MR04S features an intricate mechanical marble run powered by an automatic gear-driven lift system that keeps steel marbles moving continuously through more than 182 cm of track. Inspired by the mysterious world of alchemy, the model includes glowing towers, crystal-inspired mechanisms, exposed gears, and detailed architectural elements that create a spectacular kinetic display.
Designed with 247 precision-engineered pieces, this interactive model offers an enjoyable assembly experience for teens and adults who appreciate engineering, mechanics, and creative DIY projects. Seven programmable lighting zones provide more than 120 lighting combinations, while Sport Mode synchronizes the lights with the moving marbles and Viewing Mode creates a relaxing illuminated display when the marble run is paused. The USB-C powered automatic lift continuously returns marbles to the top of the track, allowing endless movement without manual resetting.
