FAQ

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.
