Our TOP 5 Most Challenging Lego Sets
“A Monster Lego Build!”
Our Rating: 4.5
Kicking off our most challenging Lego set list is this Bucket Wheel Excavator set, and boy, it’s a real doozy.
If you’re talking about challenging Lego sets, then you’re probably looking for BOTH size and a complex construction that only the most difficult Lego builds have.
Well, look no further than this Lego Technic Bucket Wheel Excavator, because it delivers those things in spades.
Then again, the Lego Technic line is known for being some of the most complicated Lego set builds out there.
Except in this case, the company seemed to have cranked the meter up to 11.
It gives fans and collectors something that will not just give them joy, but test your brick building chops as well.
A Gargantuan Build
We’re telling you: this one isn’t playing, as it contains nearly 4000—yes, you read that right—pieces.
Only fans of the most difficult Lego builds would probably dare take this on.
Seriously, though, this is one glorious set that rivals the Lego Star Wars Death Star or the Lego Ideas Taj Mahal with its sheer size alone.
Yeah, it stands a relatively measly 16 inches tall (standard, considering its 4000 bricks).
However, it has the length and girth that would make the TIE Fighter look like a fly.
You should know this: this Lego Technic Bucket Wheel Excavator is more than two feet long.
Now THAT is a monster right there, but in all the best ways.
Additionally, the set also comes with a relatively large mine truck once you finish building everything, which is about 7 inches long and 3 inches tall.
A great deal all in all!
Not for the Weak!
There’s another thing that adds to its credentials as a true entry into this most challenging Lego set list.
The 4000 bricks here aren’t what you’d normally expect from something like Star Wars Lego sets or a Lego CreatorTower Bridge.
We’re dealing with Lego Technic here, so expect a lot of pegs and rods in this build.
That makes it one of the more refreshing and unusual sets out there even for the most tried and true Lego heads in the world.
The largest Lego set comes with at least a single power function, and this bucket wheel excavator does not disappoint.
It’s got numerous motorized functions, from the excavator itself and right down to its tracks.
That warrants it as one of the most complicated Lego set builds out there.
Not So Cheap
However, challenging Lego sets like this one come at a pretty hefty price.
So suffice it to say that this is not a great starting point for Lego newbies out there.
This is the kind of set for collectors and builders alike who’ve gone beyond the simple stacking and clamping of bricks.
This is absolutely serious, and well worth putting in this most challenging Lego set list.
“A Complex and Glorious Set”
Our Rating: 5
We here at Shrunk Collectibles are fans of the Lego Star Wars Death Star, the Han Solo carbonite scene, or their host of modular building sets.
But there’s just something about the Lego Technic line that lends itself to being shoo-ins for this most challenging Lego set list we have for you.
The thing is, the most complicated Lego set out there doesn’t always have to rely on size.
Sometimes it’s all about the pure, mind-boggling builds that only the most challenging Lego sets could bring.
Case in point: this Bugatti Chiron set from Lego’s Technic line, which is based on the real-life vehicle.
Honestly, we’d say Lego has done more of a stellar job than other brands out there in creating a toy version of this car.
Need for Speed
Do you like to relish each and every rod or peg from any given Lego Creator or Star Wars set?
Or are you the kind of brick player who likes to finish things as fast as possible?
Either case, this one will surely cater to your tastes.
Despite its large brick count—approx. 3600 pieces—you’ll still end up being in awe of what a number of interconnected Technic rods could produce.
In this case, it’s a gorgeous model of the Bugatti Chiron, and its size—though not the largest set ever—is nothing to trifle with.
At almost two feet long, this is a display model through and through.
It’s not the kind of build that you could put your Han Solo or Joker Manor character minifigures in.
And one of the most impressive qualities of this set is how relatively smooth and seamless it is.
That is something that you usually won’t expect from the company.
True to Life
This is the most difficult Lego build that we’ve seen that focuses more on the interior of things than the exterior.
By that, we mean that Lego put it upon themselves to even replicate the engine of the Bugatti Chiron in this model.
That means you could pop open the hood and see all the glorious inner workings of the thing.
As far as challenging Lego sets go, this is the most complicated Lego setwe’ve encountered that doesn’t need a power function.
It’s all about the looks and the accuracy with which the company translated the real-life vehicle into Legos.
Not Exactly Cheap
With over 3600 pieces in it, we will say this: it doesn’t come cheap.
But it’s relatively affordable compared to other of the most challenging Lego set entries we have for you.
Simply put, Rob Leane would be proud of this magnificent Lego Technic set!
“An Inspired and Complex Build”
Our Rating: 5
The largest Lego set comes with more than 3000 pieces, but that doesn’t mean that the most challenging Lego set should.
And this Lego Architecture proves just that: it’s got half the brick count but nearly double the complexity when you try to build it.
The company’s very own architecture line has a more serious tone to their offerings.
That is unlike the Lego Creator Apollo Saturn, Star Destroyer Star Wars set, or other Lego modular buildings out there in the world.
Of course, that’s not a knock on all those other lines from the company; they’re all great in each of their own ways.
But here, though, we have the most difficult Lego build you could find that’s also one of the most deceptive.
Hail Lady Liberty
At first glance, you might think that this is as simple as piling up a bunch of bricks.
Similar tothe way you would a TIE Fighter, a Lego Builder car, or a Lego Creator barn yard.
But you’d be mistaken.
This is one model that features some of Lego’s best work when it comes to creating the most challenging Lego setexperience they could give you.
Sure, you’re dealing with a relatively low brick count here as far as the most complicated Lego set pieces are concerned, but 1600 bricks aren’t a joke.
Take it up a Notch
This set is one of the most ideal models you could go for if you’re transitioning from easy, simple builds to more complex ones.
It doesn’t have the logistical nightmare that sets of 2000 or more give you.
All the while retaining the complexities and intricacies that you’d look for in a serious Lego set.
At over 17 inches tall, this is a perfect centerpiece for all you Lego Architecture fans out there, not to mention it does the iconic American statue justice.
But what we love most about this model is how it gives you a prime example of what Lego’s design sensibilities are.
From its base to Lady Liberty herself, which is rife with Lego’s design sensibilities, this model shows range.
And by that, we mean that Lego is very versatile and flexible when it comes to coming up with their designs.
It shows you that not all Lego models need to look like 8-bit caricatures of the real thing.
More of a Display Model
Given that this is a Lego Architecture model, don’t expect any power function or modular buildings here.
This is a full-scale model meant almost exclusively for display than, well, play.
Still, nothing’s stopping you from doing that.
Maybe a few adjustments here or there and you could put some golden arches right behind Lady Liberty for a more grandiose effect.
“A Classic Lego Vehicle”
Our Rating: 5
Next up on our most challenging Lego set list is none other than the Lego Star Wars Millennium Falcon.
After all, this one is a no-brainer to belong in this most challenging Lego set list.
This is a set—in all of its iterations and releases—that’s become nearly synonymous with the company.
And we’re not even talking about their deluxe falcon offering.
This is the standard version, which—in our humble opinion here at Shrunk Collectibles— strikes the perfect balance between fun and complexity.
Not Too Many Pieces
Speaking of balance, this is a set that won’t bombard you with a nearly inhuman brick count, as it contains a relatively humble 1329 pieces.
When put together, though, you could bet your bottom dollar that you’re ready to blast some Star Destroyer or TIE Fighter into orbit a la Han Solo!
The Force is Strong
As far as Star Wars Lego sets go, this one is pretty much on par with the Lego Star Wars Death Star.
They’re equal in terms of their status as an icon in the company’s line.
Additionally, much like other star ships and scene models from the franchise and their Lego versions, this Lego Star Wars Millennium Falcon is to scale with their minifigs.
So, if you want to put Han Solo or Chewie in the cockpit, there’s no problem there.
Or even if you want to do a crossover and have some Marvel or DC characters piloting the iconic Corellian freighter, then you can do so.
Plenty of Minifigures
And speaking of minifigures, this set’s pretty generous with it.
It contains:Han Solo, Chewie, Rey (Skywalker or Palpatine, whichever floats your boat), Tasu Leech, a Kanjiklub gangster, and everyone’s favorite ball droid, BB-8.
Punch It, Chewie
This one has features similar tomodular buildings, meaning you could open up the whole thing and turn it into a wonderful playset.
Additionally, this ship comes with a couple of missile launchers as well.
And that’s pretty standard for the falcon in all its iterations within the Lego universe.
There’s one thing that makes this such a stand-out entry in ourmost challenging Lego set list.
It is the fact that it’s a perfect Lego version of something that we only otherwise see onscreen.
Not only do we have a soft spot for Han Solo and the gang, but also this is just an iconic model all in all.
As for its price tag, it is relatively affordable especially when compared to the deluxe falcon that Lego released before.
Overall, you have yourselves one of the best challenging sets out there.
“A Nice, Convertible Lego Set”
Our Rating: 5
If there’s one Lego model that proves that challenging Lego sets don’t always need to have more than 1000 bricks in it, it’s this one.
The iconic Chevy Corvette comes to you in Lego’s patented Technic form, and in approximately about 600 bricks to boot.
Now, now: 600 bricks might not seem like much if you’re a Lego addict, but hear us out.
This is one build that shows that Technic line’s trademark qualities in spades.
It includes heavy use of pegs and rods, relatively seamless final product, and a pretty accurate rendering of the real thing in Lego form.
6 Hours of Building
Simply put, this should be a set that you could finish within 4 hours in any other instance.
But given how the Technic line loves to challenge its builders, it’ll take you about 6 hours here.
And that’s a good thing: the most complicated Lego set, after all, shouldn’t be just a walk in the park.
Muscles and Engines
It’s such a delight to see that even in Lego form the Chevy Corvette doesn’t lose any of its gritty appeal.
From its four tailpipes to its adjustable engine features, both gearheads and Lego heads alike will definitely have something to appreciate in this model.
Plus, that burnt orange color scheme that they used is loud in a good way and perfectly encapsulates the Corvette’s whole schtick.
On the downside, given how complex this build is, it’s pretty much a bummer to find out that you’re not getting a physical instruction manual in this set.
Instead, Lego chose to go all paperless and give you the instruction manual online.
That means you’ll need an internet connection in order to find out how to construct this muscle car.
Build and Convert
However, our favorite feature here is the fact that you’re actually getting two models here for the price of one.
Yes, the Chevy Corvette is already a badass model that you could enjoy on its own.
But the fact that you could also use the exact same bricks here to construct Lego’s version of the Hot Rod is just amazing.
Really, the company went a step above here, as they don’t usually provide multiple builds for their sets regularly these days.
It’s almost like it’s the 90s or the early 2000s, so they even get some nostalgia points there!
As for the price, yup, this won’t break the bank either; it’s one of the generally affordable sets available out there.
The Most Challenging Lego Set List—Our Verdict
Whether you want models with massive brick counts, exclusively complex builds, or something in between, the company doesn’t have a shortage of what they could offer you.
Whether it’s the Lego CreatorTower Bridge or the Apollo Saturn, the great thing about these bricks is how you could make your builds as complex as you want.
And that’s what makes Legos so iconic: even the most challenging Lego set out there doesn’t necessarily have to be so rigid.
You could always let your imagination fly and make your own model!
So go ahead pick the most challenging Lego set and immerse yourself in some laborious yet fun brick building.
