38 lessons, one idea at a time

The whole curriculum

Every lesson your kid can work through. The beginner arc runs in order; after that, several tracks open in parallel so they follow what excites them. We've left out the bodies — those live in the editor — but here's exactly what each one teaches.

After the lessons?

The editor ships with a shelf of starter games — snake, asteroids, platformer, flappy parrot, a few more. Kids open one, read it, change anything, see what happens. That's where they stop following lessons and start making.
