Frequently asked questions
Is this actually educational, or is it just a light-up toy?
It's genuinely educational. Circuit Maze teaches real electrical circuit logic: positive and negative terminals, current flow, and how components connect in a working circuit. When that fan spins because they built the circuit correctly, they understand electricity in a way no worksheet can teach.
My child is 3. Isn't that too young for circuits?
The early levels are designed specifically for ages 3–5 — simple two-block connections with big, obvious payoffs (the astronaut lights up, the fan spins). There's no reading required, and the on-screen visuals guide young kids through each step. By age 6 or 7, they'll be working through multi-component puzzles independently. The 50-level progression means it genuinely grows with them for years.
Do I need to buy batteries?
Nope. The board has a single power source - a rechargeable 14500 lithium-ion battery (3.7 V, 500 mAh, included), which can alternatively be replaced with 3 × AA (not included), charged via a 5 V USB charger.
My grandchild already has a lot of STEM toys. What makes this one different?
Most STEM kits give you a bag of parts and a booklet. Circuit Maze has 50 puzzles built into the board — no paper cards, no booklet to lose, no setup required.
Is the projector bright enough to actually see?
Yes, it works best in a dimmed room or at night, projecting stars and planets across the ceiling or a wall. It's become a favorite bedtime activity for a lot of families.

As seen on
Every Wire Is a Guess. Every Win Builds a Thinker.
Kids snap the pieces together, flip the switch, and find out right away if they nailed it. The fan spins, the light pops on, stars fill the ceiling. There’s nothing to explain. They just dive in and keep at it until it works.
Thinking They Can Actually See
Every puzzle comes down to one question: which way does the power go? When the light flips on, they know they figured it out.
Science They Build Themselves
They see electricity make something they built actually move. Science isn’t a school word anymore. It’s the thing on the kitchen table.
Grit First, Then “I Did It!”
When it doesn’t work, they move a piece and try again. When it finally lights up, that big grin is 100% earned.
No Apps. No WiFi. No Fuss.
Charge it, turn it on, hand it over. That’s it. Real hands-on fun that keeps them busy for hours, and nowhere near a tablet.

Bought this for my grandson’s 5th birthday and honestly I wasn’t sure he’d get it. Well, he figured out the first few puzzles before I even finished my coffee lol. Every time the fan kicks on he yells “Grandma LOOK!” He asks for it the minute he walks in my door now. Best gift I’ve given in years.

I’m a retired electrician so I was a little skeptical, but this thing is legit. My granddaughter and I sit at the kitchen table and work through the levels together. When one doesn’t work she just moves a piece and tries again, no meltdown. Proud grandpa moment when she explained to her dad how the circuit works.

Finally something that beats the iPad in our house. My 6 year old will sit with this for an hour straight, which is basically a miracle. No app, no wifi, just charge it and go. The projector at bedtime is a huge hit too. Already ordered a second one so her brother stops “borrowing” hers.

Our Story
It started with a drawer full of toys nobody played with.
We picked STEM Circuit Puzzle Board because it’s the kind of toy kids keep coming back to, long after the wrapping paper hits the trash.
Like everything in our store, it passed our one big test: we’d happily give it to our own little ones.
