One set is fun. Two sets feel like a whole new world.
That’s the big shift when you move from small builds to mega builds with Biggo Blocks. A single box of jumbo building blocks is perfect for learning the basics. But once kids start dreaming up forts, towers, and walk-in worlds, they eventually hit a wall.
Here’s how to recognize that single set ceiling, what happens when you add a second set, and how to choose the right upgrade so your builder can fully enter Big Build Mode.
Where Single Jumbo Building Block Sets Builds Tap Out

A single set of jumbo building blocks goes a long way:
-
Kids learn how pieces connect
-
They practice stacking, symmetry, and basic patterns
-
They can build small towers, simple walls, and mini houses
That’s an important phase. But sooner or later, you’ll see signs that your builder is running out of room and jumbo blocks.
1. The tower can’t go any higher
You’ll notice the same pattern: the tower reaches a certain height, then stops. Not because your child ran out of ideas, but because they ran out of blocks. The “limit” isn’t their imagination; it’s the piece count.
2. Builds keep getting recycled
They build a little house… then take it apart to make a car… then take that apart to make a robot. Constant rebuilding is great practice, but it also means they never get to live with a big finished build.
3. Siblings are waiting for pieces
When more than one child is building, a single set of extra large building blocks can become a bottleneck. One kid has the long pieces, another needs more of a certain color, and someone always ends up waiting instead of creating.
That’s the single-set ceiling. The moment when ideas are still flowing but the block supply just can’t keep up.
What 2 Jumbo Building Block Sets Unlock (Big Build Mode)
Adding a second set doesn’t just give you “more of the same.” It changes the scale of what’s possible. You move from small tabletop builds to mega builds that fill the room.
Here’s what 2+ sets of jumbo blocks unlock:

1. Bigger, Taller, More Stable Structures
With more blocks, kids can:
-
Turn a knee-high tower into a floor-to-ceiling skyscraper
-
Build a walk-in fort or block house instead of a tiny lean-to
-
Create wider bases and thicker walls for better stability
Instead of stopping when the pieces run out, they can keep reinforcing, testing, and improving. That’s real structural thinking; weight distribution, balance, and support emerging through play.
2. Longer, Deeper Play Sessions
More pieces = more possibilities before anything has to be taken apart.
Kids can:
-
Keep the “big build” up for days while adding new sections
-
Run stories and games inside their creations
-
Build accessories like vehicles, robots, pets, and furniture around a main structure
Those extra layers turn jumbo building blocks into a full environment, not just a quick activity. Focus, persistence, and problem-solving all get more reps.
3. True Collaborative Building

With two sets of extra large building blocks, collaboration finally feels natural:
-
One child can work on the tower while another builds the entrance
-
Siblings can each design a “wing” of the same fort
-
Friends can build robots, ramps, and obstacle courses that all connect
Instead of competing for pieces, kids can specialize. One planner, one builder, one tester. That’s early teamwork and project thinking wrapped inside play.
How to Pick Your Second Set
Ready to move into Big Build Mode but not sure which set to add? Here’s how to choose a second set that multiplies what you already have.
Option 1: Same Color = Clean, Architectural Builds
If you love a minimal, cohesive look, choosing a second set in the same color is the way to go.
Best for:
-
Parents who like tidy, uniform builds
-
Kids who enjoy “realistic” builds like houses, castles, and city walls
-
Classrooms or playrooms where you want a calm visual backdrop
Two matching sets of jumbo blocks create tall, bold structures that feel like real architecture. Great for design-minded kids.
Option 2: New Color = Creative, Pixel-Style Designs
Adding a new color set turns your build into a canvas.
With a second color, kids can:
-
Create stripes, gradients, and patterns on towers and walls
-
Design pixel-style art like hearts, letters, or characters right into their builds
-
Assign “roles” to colors: roads, water, lava, plants, etc.
This is where jumbo building blocks turn into visual storytelling. Color becomes part of the blueprint, not just decoration.
Option 3: Mix in 92-Piece Big-Block Sets for Mega Scale
Already have a standard set? Pair it with one of the 92-piece big-block sets to change the entire scale of your builds.
Why mix sizes?
-
Bigger pieces fill space fast, giving you mega-tall towers and giant walls
-
Smaller pieces add detail, windows, and custom shapes
-
Mixed sets let kids think in both “big structure” and “fine detail” at the same time
It’s like giving them both the framing lumber and the finishing tools for their imagination.
Putting It All Together: Enter Big Build Mode

When you move from one set to two, you’re not just buying more blocks. You’re giving your kids:

Room to follow through on bigger ideas

A chance to practice planning, iteration, and structural thinking
All with the same safe, durable jumbo blocks they already love—just in Big Build Mode.
