Marble Run Tiered Hoist – wooden 3D puzzle from Ugears The fun with marble runs continues with Ugears' Marble Run Tiered Hoist, the third in a series of Ugears modular marble runs. This unique entrant in our growing collection of entertaining wooden marble runs features a 3-tiered stair lift that raises the marbles to the top for amusement park adventures. This wooden DIY kit is both a 3D puzzle and a fun toy. The Marble Run Tiered Hoist features a fascinating lift, three new track elements, and interesting trap and release mechanisms sprinkled throughout. Turn the hand crank and watch the marbles make their journeys through various obstacles down to the collection tray below. Multiple tracks and elements are packed into a compact space in this well-designed DIY marble run. Which marble will take which track, and what adventures await? Guessing is part of the fun. The Marble Run Tiered Hoist has three main marble tracks. The first features a marble trap in which three marbles must work together to make their escape. The third ball is the hero, opening the gate for the second trapped marble, which in turn opens the gate for the first—teamwork! All three marbles then escape down a well. The second track is a speedy roller coaster, and the third is a four-level ramp descent. All marbles come to rest in the collection tray, where they form an orderly line behind a gate, waiting their turn for more adventures! A special rocker arm presses the gate down and carries each marble to the return track, where they run like excited school children back to the tiered hoist to begin the next ride.
