All ROKR marble runs are designed as sci-fi themed mazes, combining engineering and physics with 3D puzzles. They let you enjoy the fun of hands-on assembly and, after building, the thrill of watching steel balls race through the tracks. Once assembled, you can power them by turning a hand crank or using an electric motor, sending the steel balls on an endless, high-speed, and exciting journey.

Not all marble run sets can be connected. Currently, Marble Spaceport and Marble Night City can be expanded using a link pack. In addition, the ROKR Parallel World series marble runs also support expansion.

Glue isn't necessary as pieces are laser-cut within 0.05mm precision to fit snugly. Wax or candle stubs may be used to lubricate moving parts, and basic tools like a screwdriver, a pair of tweezers, and a small nail file may come in handy to complete construction, though most kits already have them.
