Some toys are just toys. Others open doors. The Gears! Gears! Gears! Build & Bloom set belongs in that second camp. With 116 colorful pieces—gears, flowers, and butterflies—it turns little hands loose on big ideas. Kids aged 4 and up don’t just play with this set; they build, design, and tinker. In the process, they discover how things work—and more importantly, how to figure things out for themselves. This makes it one of the best STEM toys for 4 year olds and up.
This isn’t just another box of parts. It’s a lesson in curiosity, patience, and problem-solving, cleverly disguised as fun. As a STEM toy, it engages children to explore basic mechanics and engineering concepts.

How It Works
The concept is simple. Start with a base plate, fit the gears together, and twist them into motion. It’s a hands-on introduction to basic mechanics, teaching kids how parts work together to create movement. They experiment, learn by doing, and discover how small changes affect the whole design.
There’s something special about the way this set sparks both focus and joy. Kids aren’t just connecting pieces—they’re figuring out how things connect. They try, fail, swap parts, and try again. Every new build brings a small victory, a little thrill of discovery. This is where curiosity grows—piece by piece, gear by gear. It’s one of the best STEM toys for nurturing these important skills.

Who Will Love It?
This set is perfect for kids who love to build and explore, especially those aged four and up. It’s an ideal gift for parents and grandparents who want to see their little ones think creatively and learn through play. It’s not just for kids either—families who enjoy spending time together will find plenty of joy in working side by side on a shared project.
There’s magic in the moments when a child proudly shows off a spinning gear system they built from scratch, or when an adult steps in to help with just the right piece at just the right time. These small shared moments build more than toys—they build bonds. This is why it’s one of the best STEM toys for 4 year olds and up.
A Word from Parents
One parent wrote about how their four-year-old dove into the set without hesitation, building setups with ease. “It’s fun to watch him focus,” they said. “He’s not just building things—he’s figuring out how things work.”
Another parent mentioned expanding their set with the Super Set for more variety, saying, “This is one of those toys that keeps giving. I can see my son playing with it for years, much like LEGOs.”
But not every review sings its praises. One parent returned the set after discovering the stickers didn’t fit properly. “Neat idea, poor execution,” they wrote. “The base pieces are too light, and one part broke after the first day.”
What It Does Well
- Hands-on learning, the old-fashioned way. There’s no screen involved—just gears to fit, bases to connect, and pieces to adjust until everything works the way it should. Problem-solving happens naturally, one twist at a time.
- Endless creativity. The interchangeable parts allow every project to be unique. No instructions required—just imagination and trial-and-error.
- Durable enough for rough play. Kids will drop it, step on it, and pull it apart. The pieces can take it, which means the fun keeps going, day after day.
Where It Comes Up Short
- Some fragile parts. Reviewers mention that a blue spring broke soon after opening. That kind of flaw can disappoint.
- Sticker trouble. Certain stickers don’t align with cut-outs, making them tricky to use—and frustrating for kids.
- Limited pieces for big ideas. The 116 parts might not stretch far enough for more ambitious builders. Expansion sets may be necessary down the road.

Final Take
The Gears! Gears! Gears! Build & Bloom set isn’t flawless, but it’s the kind of toy that offers more than just entertainment. It introduces children to the joy of figuring things out—the thrill of small discoveries that add up to something bigger.
Sure, there are a few bumps—fragile parts, sticker glitches—but for every small frustration, there’s a much larger reward: a child learning that persistence pays off. They’re not just building flowers and gears. They’re building confidence.
This set may not be perfect, but the lessons it offers are. And in the end, that’s what makes it worth it. Because the real joy in STEM toys like these isn’t just what they create—it’s what they inspire.
