This Steampunk Perpetual Marble Machine feels like the Ultimate Desk Accessory for LEGO Enthusiasts

Building it is just half the experience… Once it’s assembled, JMBricklayer’s Steampunk Marble Run works as a perpetual machine of sorts, creating a dynamic mechanical toy that’s always running on your desk. A rollercoaster for marbles, this over-5300-piece marvel offers a closed-loop design featuring interweaving paths, flamethrowers, dinosaurs, and nuclear reactors… all made from bricks of course. The entire structure measures a whopping 24.8 inches tall, and runs on two motors powered by a battery module. A perfect desktop toy for LEGO and other brick enthusiasts, puzzle geeks, pinball nerds, gamers, steampunk-lovers, and just fun YouTubers who like to have an interesting toy in the background of their vlogs, the Steampunk Marble Run’s $158 price tag makes it a no-brainer for people looking for a challenge.

This isn’t your dad’s LEGO set. It’s rated extremely difficult, with over 5,391 pieces that come together over days of painstaking work. The result, however, is beyond glorious. The entire set looks like something out of a mad scientist’s playroom. The GBC(Great Ball Contraption) features multiple paths and a randomizer that sends marbles on unique journeys. The balls roll down these dizzying routes, overshadowing any Hot Wheels track you could have ever built in your life, and make their way to the bottom of the contraption. A lift then carries them back up to the top, where the entire process repeats itself… with different results every time.

The entire Steampunk Marble Run set is the visual representation of a sensory overload. It’s so incredibly detailed you end up discovering new things every time you observe it from a different angle. The 2-foot-tall structure has industrial equipment, prehistoric monsters, chemical tanks and nuclear reactors, flamethrowers, two different kinds of lifts, and just random rails/paths connecting them all together into a symphony of sheer chaos.

The way the Great Ball Contraption is visually complicated, but theoretically simple. A battery module powers the entire set, delivering juice to the two lifts that carry the marbles up, and the stairways that also help move the marbles around. However, once the marbles hit the tracks, gravity and randomness kick in. Multiple tracks allow your marble to take a unique path of its own, and objects and obstacles on the journey help the marbles change their paths midway. For example, the T-Rex model at the center plays a role in moving marbles around. Its spine has a two-way switch that allows marbles to go either left or right, and the flamethrower emerging from its mouth also nudges balls into different routes, pushing them down a funnel that diverts them thanks to the same two-way switch.

Although JMBricklayer’s set doesn’t use official bricks from ‘that one famous plastic brick company’, it’s designed to be compatible with them… so if the 5,391-brick megastructure doesn’t feel detailed enough, you can actually add more to it and customize it in different ways. With that many pieces and an ‘extreme’ difficulty rating, the entire set should take days or weeks to put together depending on how proficient you are. There’s a detailed guide that comes with your kit, which should definitely make things easier… but don’t expect it to be as simple as putting together an IKEA sofa set.

Other details add to the Steampunk Marble Run’s gloriously otherworldly design. The color palette is overwhelmingly grunge-inspired, evoking an almost Mad Max style. Meanwhile, you’ve got a combination of industrial machinery, pipes, girders, chains, flamethrowers, Gatling guns, chemical tanks, nuclear reactors, and two dinosaurs dominating the design. The kit comes with a battery pack that lets you input 6 AA batteries to run the entire experience. The battery pack powers two motors that control various aspects of the marble run, and the entire set includes 10 marbles as a part of the experience… although you can absolutely add a few more of your own.

The Battery Module

The entire kit is an experience to be had. It measures 22×21 inches in length and width, with a 24.8-inch vertical that has allows the kit to look positively monstrous. The complete gizmo also weighs a staggering 15.4 lbs (or a whopping 7 kilos), so it’s best if you placed it away from overtly curious/enthusiastic pets and children. The set starts at $189.99, although JMBricklayer is offering early backers an 18% discount, bringing the full kit to $158 excluding shipping. Grab yours now and the Steampunk Marble Run ships starting August 2024.
