Techlings

How do phones and AI actually work?

Techlings is 30 mini games that let you feel how tech works, just by playing.

Switch traffic lights so no cars crash. Overlap distance rings to dig up treasure. Send a jewel with only padlocks so the nosy cat can't peek.

Each game turns a real idea from phones, the internet and robots into its rules. No memorizing: you move things with your own hands until it clicks.

AI, encryption, GPS... You've heard the words. Now feel what's inside.

No jargon, no lectures. Clear a stage and a "How it works" note shows where that idea is used for real, so it sticks the next time you hear it.

Your first game is free.
