Tiny rhythm games for the minute you spend waiting on a build, a test run or an AI agent. Tap along and the music settles into your tempo. You can't lose, it never gets harder, and when you look away it plays itself.

Waiting on a machine is an awkward kind of break. It's too short to start something else, but long enough to reach for your phone and lose ten minutes. These games are made for that gap: something for your hands while your head stays on the problem, and an easy way back when the wait is over.

It finds your tempo.
