Robotime London Marble Run DIY Wooden 3D Puzzle

Construct London's famous attractions like the London Eye, Big Ben, and the Tower Bridge with this DIY 3D wooden puzzle marble run, then travel through them in a speedy, adrenaline-filled journey.

Prepare for a whirlwind tour of the British capital without ever leaving your room with this mechanical wonder disguised as a hands-on 3D wooden puzzle. You get to go sightseeing with the help of precision engineering and some miniature versions of the Big Ben, the Tower Bridge, and the London Eye. Cross the Thames and board the double-decker bus or the Tube and get to your destination in a jiffy, while metal spheres zip through ramps and tunnels through the power of gravity and a sturdy motor. Even the Crown Jewels make a cameo appearance, all without triggering the royal alarms. Laser-cut, interlocking parts make this marble run's build satisfying and highly rewarding. It makes for smooth, high-octane play, so we're not stopping for tea until you switch the toy off. Until then, we can tour the city as many times as we like.
