Lego Ninjago shouldn’t have lasted this long. Honestly. Back in 2011, when the first wave of lego ninjago masters of spinjitzu sets hit the shelves, the plan was simple: run it for three years, sell some plastic spinners, air a cartoon tie-in, and then pivot to the next big thing. Legend has it—and by legend, I mean actual accounts from the Lego design team in Billund—that Chima was supposed to be the successor. But the fans didn’t want Chima. They wanted the ninjas. They wanted Kai, Jay, Cole, and Zane. They wanted the specific, weirdly satisfying click of a plastic dragon wing and the chaotic energy of a spinjitzu battle.
Fast forward over a decade. We’ve seen movie tie-ins, soft reboots, "Core" lines for younger builders, and complex "Dragons Rising" arcs. The theme has survived because it isn’t just about ninjas. It’s about a constant, restless evolution of design.
The Mechanical Magic of Spinjitzu
When people talk about lego ninjago masters of spinjitzu sets, they usually focus on the minifigures. I get it. The prints are incredible. But the real genius is in the kinetic play. Remember the original 2011 spinners? They were basic. You put a minifigure on a weighted base, gave it a flick, and watched it clatter into your sibling's set. It was tactile. It was messy.
By the time we got to the Airjitzu flyers and the later Spinjitzu Burst sets, the engineering had shifted. Lego designers started treating these sets like mini physics experiments. You weren't just building a static model; you were building a launcher.
The variety is wild. One year you're building a dragon with folding wings, and the next, you're looking at a "Titan Mech" that has better articulation than most high-end action figures. Take the 71765 Ninja Ultra Combo Mech. It’s basically a Voltron-style build where four separate vehicles—a jet, a tank, a driller, and a smaller mech—snap together. If you grew up with 90s toys, this is the dream. It’s heavy. It’s chunky. It’s got that specific "swooshability" factor that designers like Niek van Slagmaat (a lead designer on the theme) often talk about on social media.
Why the Dragons Keep Changing
You’ve probably noticed there are a lot of dragons. Like, a lot.
Every wave of lego ninjago masters of spinjitzu sets seems to include at least one oversized lizard. But if you look closely, the building techniques have changed drastically. The early dragons, like the 2260 Ice Dragon Attack, used specialized, molded heads. They looked okay, but they felt like "juniorized" parts. They lacked the "Lego-ness" of a brick-built solution.
Modern Ninjago has abandoned those big molds. Now, we get these intricate, SNOT-heavy (Studs Not On Top) designs. The 71774 Lloyd’s Golden Ultra Dragon from the Crystalized line is a beast. Four heads. Massive gold wings. It uses ball joints and Technic connectors to create a creature that feels alive. It’s also a nightmare for shelf space. But that’s the trade-off.

The shift toward brick-built heads was a turning point. It allowed for more expression. It meant that if you didn't like the look, you could mod it. That’s the core of the Ninjago community—constant modification. You’ll find thousands of "MOCs" (My Own Creations) online where builders take a standard Ninjago dragon and turn it into something out of a dark fantasy novel.
The Legacy vs. Core Debate
There’s this weird split in the fandom right now. You’ve got "Legacy" sets, which are basically remakes of older, classic sets using modern parts. Then you’ve got "Core," which is designed to be the entry point for kids who don't care about the complex TV show lore.
Kinda confusing, right?
The Legacy sets are for the nostalgia crowd. They take something like the 70618 Destiny's Bounty and refine it. Speaking of the Bounty, that ship is arguably the greatest Lego set ever made across any theme. It’s a junk boat with dragon heads and a full interior. It perfectly captures why Ninjago works: it’s a mashup. It’s high-fantasy meets cyberpunk meets traditional Japanese architecture.
The Collector's Trap: Minifigures and Scarcity
Let’s talk about the secondary market. If you’re getting into lego ninjago masters of spinjitzu sets for the investment, you're playing a dangerous game. Some figures, like the "NRG" versions from the early seasons or the "Killow" big-fig, go for absurd amounts of money on BrickLink.
Lego knows this. They’ve started including "Golden" anniversary figures in certain sets to drive sales. It works. You’ll find yourself buying a $40 jungle trap set just because it has the one specific version of Kai you’re missing. It’s a bit of a grind. But the level of detail on these figures—the dual-molded helmets, the shoulder armor, the tiny printing on the toes—is consistently higher than what you see in the Star Wars line for the same price point.
The sets are often packed with "play features." This is Lego-speak for "stuff that moves." Flick-fire missiles, hidden compartments, spring-loaded shooters. While adult collectors might find them annoying, they are the reason these sets sell. They aren't statues. They're meant to be crashed.

The Evolution of the "Big" Sets
Ninago isn't just for kids anymore. The Ninjago City modular series changed everything.
- 70620 Ninjago City: This set is a masterpiece. 4,800 pieces of pure detail. It looks like something out of Blade Runner. It has a sushi bar with a conveyor belt, a comic book store, and a working elevator.
- 70657 Ninjago City Docks: A horizontal expansion that added a grocery store and a map room. It's quieter than the main city but adds so much flavor.
- 71741 Ninjago City Gardens: A massive tower that celebrates the 10th anniversary. It’s tall, colorful, and contains references to almost every season of the show.
These sets proved that lego ninjago masters of spinjitzu sets could compete with the "Adults Welcome" Creator Expert line. They are dense. They use clever "part usage"—like using a black crowbar for a railing or a clear garage door piece for a fish tank. If you want to see what Lego designers can do when the budget is "yes," these are the sets to look at.
Why Ninjago Beat the Competition
Lego has tried other "action" themes. Nexo Knights. Hidden Side. Dreamzzz.
Most of them fizzle out after two or three years. Ninjago stays. Why? It's the characters. The TV show (which has been running since 2011) gives kids a reason to care about the red ninja vs. the blue ninja. When a kid buys a lego ninjago masters of spinjitzu set, they aren't just buying a car; they're buying "Kai’s Katana 4x4." There’s a narrative hook.
Also, the villains are genuinely weird. We’ve had skeleton armies, snake people (Serpentine), ghost warriors, sky pirates, digital viruses, and "Vengestone" zombies. This constant refreshing of the "bad guy" aesthetic keeps the sets from feeling repetitive. You aren't just building another grey castle. You’re building a skull sorcerer’s dungeon or a neon-soaked racing arena.
How to Choose Your First Set
If you’re just starting, don't go for the tiny $10 sets. They’re fine for a quick fix, but they don't show you the "soul" of the theme.
Look for the mid-range mechs. Anything in the $40-$60 range usually has the best balance of build complexity and playability. The "Titan" mechs are usually the gold standard. They have the height, the stability, and the "wow" factor.

If you're a display builder, save your money for the Ninjago City modulars. They are expensive. They are hard to find once they retire. But they are the peak of what can be done with plastic bricks.
Keep an eye on the "retirement" dates. Lego sets usually have a shelf life of 18 to 24 months. Once a wave of lego ninjago masters of spinjitzu sets is gone, the prices on the used market spike almost immediately. If you see a dragon you like, buy it now. Don't wait for the clearance sale that might never happen.
Essential Maintenance for Ninjago Collectors
Dust is the enemy.
Ninjago sets are "spiky." They have lots of katanas, dragon fins, and golden tassels. These things are magnets for dust. A soft makeup brush is your best friend here. Don't use canned air; it’s too powerful and can pop off small 1x1 tiles that you’ll never find again.
For the stickers—and Ninjago uses a lot of them—make sure your hands are clean. Use a pair of tweezers to align them. Nothing ruins a high-end lego ninjago masters of spinjitzu set like a crooked "Dragon Flame" decal on a cockpit canopy.
Actionable Next Steps
- Check the Retirement List: Search for "Lego retirement dates 2026." Ninjago waves rotate fast. If sets like the Source Dragon of Motion are on the list, grab them before they hit 3x retail price.
- Audit Your Minifigures: If you have old sets from 2011-2015, look up the "NRG" or "Elemental" versions of the ninjas. You might be sitting on $50-$100 in a single figure.
- Try a "MOC" Build: Don't just follow the instructions. Ninjago is built for kit-bashing. Take two smaller $10 mechs and try to combine them into one larger "Ultra Mech."
- Watch the "Dragons Rising" Series: If you’ve lost track of the lore, the new series is actually a great jumping-off point and explains why the current sets look the way they do (the Merge).
- Invest in Storage: If you're buying for a kid, get a dedicated bin for the specialized "power" pieces—the translucent flames, lightning bolts, and energy rings. These are the first things to get lost, and they're the hardest to replace.
Ninjago isn't just a theme. It's a weird, neon-colored ecosystem that has outlasted almost everything else in the toy store. Whether you’re in it for the "Spinjitzu" lore or just want a cool-looking robot for your desk, there’s a reason people are still talking about these sets fourteen years later. It’s because, at the end of the day, ninjas are cool. But ninjas in giant, brick-built mechs? That’s unbeatable.
