Why it exists

Thirty new blueprints across all three difficulty levels — fresh challenges for Reactor Rescue night, or thirty new reasons to open the kit on a rainy Sunday.

This item's price is TBC — the design system's rule is that unknown figures are marked, never invented. Leave an email and it fills in the moment it's real.

about labbox

From classrooms to your table

Labbox was started by sisters Arta and Fiona Shehu, computer-science engineers who taught thousands of students at jCoders Academy — and kept seeing the same thing: a circuit only clicks when it is real. Not simulated, not on a screen. Something has to light up.

The blocks came first: 30+ magnetic electronic components that snap together with polarity marks and protected parts, so a wrong build can't hurt anyone or anything. The kits and games grew out of them, co-developed and manufactured with Hape, one of the world's largest educational-toy makers. Labbox is based in Frankfurt and ships across nine European countries.

Frequently asked questions

Do the blocks work with the other products?
Yes — every Labbox block shares the same magnetic connectors, polarity marks and protected components. Game blocks work in kits and vice versa.
Is it hard to get started?
The first circuit takes about two minutes with the manual. Pro logic projects genuinely take thought — that's the point. Every project has a video if you get stuck.
Can I buy individual blocks or replacements?
That's the plan — see Blocks & accessories. Unpriced items take a notify-me until pricing is final.
Is it safe? What about batteries?
Components are protected, so a wrong circuit can't damage anything or anyone. The battery block encloses its cells; no exposed contacts.
Which language is the manual in?
Choose EN, DE, ES, FR or IT above — one product, five manuals, not five products.

One block system. Every box plugs into the last.
