Every planet is scattered with resources, and your goal is to collect them all. You won't move a single robot yourself. You'll write Python to automate them, then watch them do the work. Once everything's gathered and the spaceship is loaded, you're off to the next planet.

Dozens of resources, each its own puzzle

A tree you just harvest. A crate you push to the ship. A pyramid you circle around. Figure out what each one wants, then write the code to pull it off.

Write Python

You write Python right inside the game. It's one of the most popular programming languages, used everywhere from web apps to data science. You're writing it from your very first puzzle. The built-in code editor has syntax highlighting, autocomplete and error detection, powered by the same technology as VS Code.

Beginner-friendly, with room to grow

No experience required. A built-in manual teaches you Python from the very first line and explains every command, resource and robot you come across, so beginners are never lost. The later planets still get tricky enough to satisfy seasoned programmers. Push further and you can write smarter, more general code that solves entire puzzles on its own.
