Turn the crank to lift the colored glass marbles upwards (one marble rises per nine revolutions of the winding crank) to the three-marble storage up top. From there the marbles begin their downhill runs through exciting elements: a high-speed slide, a vertical snake, and a mountain river.
You can connect any two or four marble runs together with special connectors (included in each kit) for a giant marble amusement park, with a variety of soaring lifts and obstacles to overcome on the descent.
The escapement at the end of each set can send the marbles back to the original hoist, to the adjacent marble run, or alternating between the two (you control this with a special weighted switch).
The Marble Run Spiral Hoist wooden mechanical model consists of 266 parts, is rated "advanced" level, and provides 6+ hours of fun assembly time. No glue or other tools are needed for assembly.
