Gearbox Tinker

Gearbox Tinker lets you run a small repair workshop. Customers bring in broken machines, and you diagnose, order parts, and reassemble them. It scratches a satisfying tidy-things-up itch.

The puzzle layer is in the diagnosis — figuring out which worn part caused the fault. Later machines get genuinely tricky. The interface is a bit busy at first but makes sense after an hour.

Fully offline, saves locally, and easy to drop in and out of. A nice low-key sim.
