Learn how things work

Real engineering, for kids. Play it, then explain it at dinner.

Machines & Motion

Levers, gears, springs — the tricks that make work easy.

Levers · soonPulleys · soonRamps · soonWheels · soonGears · soonScrews · soonWedges · soonSprings · soonFriction · soonCatapults · soon

Big Builds

Bridges, towers and dams that refuse to fall down.

Bridges · soonTowers · soonArches · soonDams · soonEarthquake-proof buildings · soonElevators · soonCranes · soon

Sparks & Circuits

Electricity, magnets, and machines that feel.

Why does the light turn on?

Electricity only flows in a full loop. Close the loop, light the bulbs.

Up & Away

Wings, rockets and parachutes — beating gravity.

Robot School

Talk to machines: steps, loops and secret codes.

What is this?

Learn is AddaZone's engineering corner for kids aged 7 and up. Every topic answers one question a curious kid actually asks — why does the light turn on? why don't bridges fall down? — with a short illustrated lesson read out loud, a puzzle game where playing IS the concept (wires really must close a loop; beams really must carry the load), and a friendly quiz that earns a bronze, silver or gold badge. Stars and badges add up to an engineer level. Everything is free, pre-written, and safe: no ads, no chat, no account needed, and progress is saved even for guests.

Fifty topics are planned across seven tracks — machines, structures, electricity, water and air, flight and space, robots and code, and everyday wonders — landing one at a time, the same way the games on this site did.
