ROBOTIME ROKR Alchemy City Marble Run Mechanical 3D Puzzle MR04S

The ROKR Marble Run is equipped with seven groups of light boxes that produce a rich variety of dynamic flashing and color-shifting light sequences, synchronized with ambient sound and the model's music. This feature transforms the rokr marble run into a spectacular, immersive display, bringing the "Alchemy City" to life on your desk. Featuring both Sport Mode (full function) and Viewing Mode (ambient light only), this dual functionality allows you to choose between maximum dynamic engagement or a soft, tranquil lighting display, perfectly adapting the rokr puzzle to your environment and mood. A core feature for Model Kits for Adults, the independent Automatic Ladder Lift Module (USB-C powered) ensures non-stop action by feeding marbles onto the 182cm-long futuristic track. This guarantees continuous, looping motion for endless fascination without manual intervention. This set includes a bonus "World Module," specifically designed for seamless horizontal and vertical connection with other ROKR Parallel World models. This allows users of the building kits for adults to easily expand their collection and construct a larger, unique, and more complex marble track universe. Designed for an easy build with its innovative jack-type panel system, this rokr model has an estimated 149 parts, a 3-star difficulty rating, and an estimated 3 hours assembly time.
