THREADMILL

One program. Every worker.

A programming game about turning a few lines of code into an industrial swarm.

Write the system

Write the code every worker runs. Watch each line act on the floor, then change it and run again.

Scale it

Start with one robot. Scale to 128. Use code to split jobs and turn a pileup into a team.

Build your Kernel

Draft upgrades called Kernel Mutations. Scan farther, build cheaper workers, or share what scouts find. See your build light up as it runs.

Build a factory

Feed raw Mass to processors. Haul finished output to base. Write the logic that keeps the whole production line moving.

Adapt

Supply shifts. Power fails. Send scouts, check the power, and keep the work flowing.

Optimize

Test your code in seeded challenges and generated facilities. Compare output, rewrite, and beat your best. More workers do not mean better code.
