Our team of designers created the Marble Run Spiral Hoist and our three other marble runs (Chain Hoist, Stepped Hoist and Tiered Hoist) as fantastic standalones, but also as modular elements able to be connected together into a super Marble Run! 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. Just snap the parts out of their laser pre-cut plywood boards and connect them together, following the detailed, illustrated instructions in 11 languages (English, German, Spanish, French, Italian, Polish, Ukrainian, Chinese, Japanese, Korean, and Russian) included in each Ugears kit.

There's something mesmerizing about marble runs. Kids and adults can get lost for hours watching the motions of these magical machines, and the Ugears Marble Run Spiral Hoist promises endless entertainment for all ages. Discover your inner engineer as you build this engaging 3D mechanical puzzle. If you're up for a challenge, why not assemble all four marble runs and quadruple the fun? You can leave the model in its attractive natural wood state or unleash your inner artist by painting our models in different colors, as many Ugears fans around the world do.

This model will become a conversation piece in your office or home and provide a fun diversion for your family members, friends and acquaintances. The Marble Run Spiral Hoist makes a great gift, either as a DIY kit or as an exciting toy you've lovingly built with your own hands.
