Product Description

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.

Whether you're fascinated by mechanical engineering, marble runs, or unique display models, this kit offers hours of satisfying assembly and long-lasting entertainment. It can also connect with other models in the ROKR Parallel World Marble Run Series, allowing you to expand your futuristic city into an even larger interactive marble run system.

The Marble Run 3D Puzzle also makes an exceptional gift for engineers, puzzle enthusiasts, STEM learners, collectors, and DIY hobbyists. Perfect for birthdays, Father's Day, Christmas, graduations, or special occasions, it combines engineering, motion, lighting, and creativity in one remarkable mechanical model.

*Notes: Other marble runs and lift modules must be purchased separately. You need to prepare 1 Type-C power cable by yourself.

The Story Behind It

The Parallel World Marble Run Series of 3D puzzle kits introduced us to alternate futures, with the Alchemy City reflecting a pursuit for immortality (infinite marble loops) and perfection (easy build with maximum entertainment). Every surface, every path, every possibility has been designed for balance, with a jack-type panel system for easy, intuitive assembly. Within the winding paths of glowing towers and crystal conduits is the concept of transformation. This is reflected in the colorful, pulsing LED lights that respond to ambient sound, the passing of marbles, and the mode the user selects.  To further draw you into the alchemical world, components were colored through a series of specialized processes to create texture and distinct layers. The result? A marble run toy that continually sparks curiosity, ever-expanding, and ever-adventurous.
