Collatz Labs

We’re building Beehive.py — learn real Python by playing.

A factory game you play by writing actual code — not blocks, not pseudocode. Command a swarm of bees, automate a factory, and build the Great Hive.

why we’re called Collatz

Take any number. Follow two rules. Where do you end up?

The Collatz conjecture is one of the simplest open questions in mathematics. Take a number. If it’s even, halve it. If it’s odd, triple it and add one. Repeat.

even  n / 2 odd  3n + 1

Do you always reach 1? Since 1937, nobody has been able to prove it. Two rules — one unsolved problem.

That’s the whole idea behind us. Give something simple a set of honest rules, and watch what grows. It’s how good math works. It’s how good code works. It’s how we build.

One game first — done right.

Collatz Labs is built to outlast any single project — simple rules, room to grow. But right now every hour goes into making the first one great: Beehive.py.

in development

The lab’s first game.

Beehive.py turns learning to code into a factory game. You write real Python to command a swarm of bees, automate a growing factory, and build the Great Hive — and every line you write is a skill you keep.

// Steam — coming soon

Beehive.py

Learn real Python by playing.

Write actual code — not blocks, not pseudocode. From your first while loop to real concurrency across four interpreters.

the two of us

A mathematician and a banker, after hours.

Collatz Labs is Johannes and Tristan — one deep in mathematics, one in finance — building after work between Roßdorf and Bottrop. No publisher, no budget, no deadline. We make the things we’d want to use, and we don’t ship them until they’re good.
