Why Stackling

Learning to code, in the gaps of your day.

Stackling is for people who want to learn to code and have a spare five minutes.

You will not type a thing.

You read real code, predict what it does, then tap and drag it into place.

Lessons are short, so a bus ride is enough.

Mistakes come back until they stick.

That is the whole idea.

How a lesson is built

A key idea
Each lesson starts with one idea, in plain words, like const is a name that never changes.
Exercises you tap
Then you answer by tapping and dragging: build a line, fix a bug, predict the output.
Feedback that explains why
Get one wrong and you learn why, then it comes back later so why becomes I know.

1,066 lessons in 27 tracks across eight paths.

Made by Sunlit Game Studio, and built with the React Native and Expo it teaches.
