ROKR LG504 Marble Run Starter Kit

The ROKR LG504 is a 3D wooden jigsaw puzzle that builds into a working marble run powered by a hand crank. It arrives as a complete starter kit with 233 pre-cut wood pieces, 10 steel marbles, a steel shaft, sandpaper, wax and illustrated English instructions. The model suits hobbyists aged 14 and over who enjoy mechanical assembly and desktop display pieces.

Upgrade from static puzzles to kinetic models

Unlike fixed wooden puzzles, this kit creates a moving mechanism where marbles travel two circular routes when the crank is turned. The jump is worth it for builders who want to see gear-driven motion and learn basic mechanical principles through hands-on construction. It replaces passive display models with an interactive desktop sculpture that demonstrates energy transfer.

233-piece kit assembles in about six hours

The finished model measures 9.92 by 8.94 by 7.99 inches and provides enough track length for continuous marble circulation on two paths. Headroom exists for repeated runs and casual demonstration of the waterwheel-inspired mechanism. Builders seeking larger layouts, motorised operation or modular expansion will need additional kits not included in this starter set.
