Reviewing the latest Neon City Cyberpunk set, Lumibricks L9095 Game Stack!

 

Creativity meets Technology!

The Lumibricks Cyberpunk Game Stack (model L9095) emerges as a beacon of innovation. Released in September 2025 as part of Lumibricks' Neon City series, this Lego compatible set reimagines the modular building block genre with a cyberpunk twist, blending towering urban stacks with an integrated LED lighting system that transforms a static model into a pulsating neon spectacle. 

Lumibricks, formerly known as FUNWHOLE, has carved a niche since its inception by pioneering light-up brick sets that go beyond traditional construction toys like Lego. The Game Stack builds on this legacy, targeting fans of dystopian sci-fi worlds—think *Blade Runner* meets arcade nostalgia—while appealing to adult collectors who crave display-worthy models with functional flair.

Let's review the unboxing, build process, design elements, and playability to see if this might be a set you'd be interested in getting.

UnBoxing

Upon opening, you're greeted by several brick bags numbered 1 through 14,  five instruction booklets—four modular guides plus a main one,  and a boxed LED lighting kit.  The haul totals 2,580 high-quality ABS plastic pieces, including 37 pre-printed bricks with UV and pad-printing techniques that deliver crisp details—no flimsy stickers here, a common gripe in budget sets. 

The real stars, however, are the 23 LED components: flexible neon tubes, color-changing strips, flashing acrylic panels, and rotating floor lights, all powered via USB or AA batteries (a removable pack adds versatility). Included lighting accessories include tweezers, and a brick separator.   Batteries not included.

Four detailed minifigures are included with one that is fully translucent.

The Build

The Game Stack consists of a raised baseplate, a tall elevator shaft and a large skeletal frame structure upon which several colourful modules or pods are connected.

The Baseplate

The raised baseplate houses various lighting elements such as neon tubes and flashing LED lights. Delicate wires are hidden in the baseplate to deliver power to the rest of the structure.  It's strongly recommended that you test each of the lighting elements either before construction or step by step as you go to make sure you don't encounter any defective components.   On the rare occasion that this might happen, Lumibricks will send you a replacement part if you contact their service department.

There are wireless connector pads on the sides of the baseplate that allow this set to be connect and draw power from other Neon City sets, such as the Neon Apartments and the Izakaya.

The Elevator

The next part of the construction revolves around the elevator shaft.  The shaft is made up of technic bricks and the elevator actually goes up and down by turning a crank.  While it's a nice play feature, the elevator doesn't actually connect to any of the floors hosting the modules.  It would have been nice to have connecting platforms from the elevator shaft to the pods.

The Robot Bar

The robot bar is fully stocked with lots of multicoloured bottles and we find the first of many printed parts that can be found in the Game Stack.  It's nicely lit from both above and below.  Because it's supposed to be a robot bar, I haven't checked to see if I can actually squeeze a minifigure behind the counter.

Behind the bar, there's an empty space with empty bottles and the first of many syringes found in the set.  Makes me wonder if the Game Stack is a actually secret haven for drug users?

The "Frame"

Here we are constructing the various elements of the frame such as the girders and platforms.  The elevator shaft gets finished off with windows.  I have my battery pack connected at all times to make sure that all the lighting is working properly during the construction process.

Here's another sampling of the printed parts that we can find in the Game Stack.  I especially like the ones that are printed are transparent parts.

In case you're wondering how all of the pods or modules get their power, there are wireless connectors mounted on each of the platforms.  There is a corresponding wireless connector on the back or front of each module and when they touch, the power from the structure will illuminate the lighting inside the module.   During my testing, some of the connections were better than the others.

The Modules

I call this the blue module.  Looks like there might be robot arms moving around so it might be off limits  for minifigures to go inside.  It splits open so you can access the interior, but you have to remove it from the platform before you can access it.  All of the modules are supposed to be interchangeable, meaning that you can freely place them on each of the different platforms.

Next up is the green module.  It's oriented at a 45 degree angle to the rest of the structure.  It houses some kind of neurotransmitter chair and the inside can be accessed from a rear panel.

The green module light connection wasn't that solid for me.  Also I found that the 45 degree angle made the module wobble, so I later ended up just fixing it to face in the same direction as the blue module.

Ok, so I'll call this one the pink module.  It's supposed to be a coin dispenser game you can take out and play.  You twist the dial at the back and coins are supposed to drop out of a slot.  Bonus if you get a printed tile.  Kids might like it. But psst, hidden on the back wall of the yellow module is another syringe, don't tell anyone.

Finally we come to the last module, it's yellow and a double decker.  The lower part houses a boxing game which you can operate from the rear and make the red and blue boxers move back and forth.  The top half houses three arcade machines which can be displayed with minifigures if you like.

It's here at the back of the yellow module, we find a third syringe.   Hmm, maybe I need to go back through the manuals and see if I missed any other ones.   But some nice printed parts are placed where typically you wouldn't notice them.

The Accessories

Besides all of the printed pieces, there's a nice assortment of accessories to the set:

A large printed but unit banner.

A golden game controller (with optional coloured joysticks included).

A drone.

A bus stop.

And finally, a sad little one eyed, one armed robot who can move around on a track.

Pros and Cons of the Game Stack

Lumibricks' hallmark—integrated lighting—reaches new heights in the Game Stack, with 23 LEDs crafting a dynamic glow and some of which activate on module insertion. Highlights include flashing acrylic panels, multi colour shifting lights on the roof, glowing neon tubes and rotating lights on the dance floor.  Compared to my other Lumibricks Cyberpunk sets, I found this one to be the most colourful.  The overall set presentation is killer and looks super amazing regardless of which side you are viewing it from.

The Game Stack structure is an engineering marvel and I found it to be quite sturdy.  Bricks as always were top quality.  Playability wise, you get interchangeable modules, a working elevator, working games to play with and a ton of accessories.

Coming into the set for the first time, I thought each of the modules were game rooms where I could populate them with minifigures but turns out only half of them were minifigure accessible.  The coin slot game was kinda meh for me.  The elevator shaft could have been better designed to connect with the modules.   And I found the number of syringes placed throughout the set a little disconcerting.

Regarding lighting, some of the wireless connections weren't that solid and to get the maximum lighting effect, you have to use fresh batteries.  When I used some older batteries, the light on the dance stopped rotating and dimmed out.  I thought it was a problem with the elements until I switched to new fresh batteries, then all was fine.

 

The light panel at the top of the building kept falling over during my construction, so I ended up adding an extra support beam on the other side to keep it in place.

Would I still recommend the Lumibricks Game Stack set?   Absolutely!  I'm a big Cyberpunk nerd so this set is right up my alley.  I like modular builds too.  I feel like this set would display nicely with some of the larger Lego Ninjago sets because they have the same colour schemes.  And if you like gaming, this set is for you too.

As with my other Lumibricks sets, I will probably make some changes to it in future, specifically inside the modules, and who knows, I might even stack it higher!
