MineMogul Wobbly machines, deep mines

Every ore chunk, ingot and box is a physics object. Belts carry loose piles of rock, and when a line backs up, the overflow tumbles onto the floor instead of politely waiting. You drop a load of ore onto a belt, watch it ride the curve, and one bad corner sends half of it bouncing down the shaft. That mess is the point: you set up filters, unclog jams, and chase down the one machine with a broken belt that has quietly filled a whole room. Other factory games run on spreadsheets and perfect ratios. This one runs on gravity, and it rewards you for designing around it.

Your factory lives inside the hollowed shell of an old cave system, and the space is not generous. Conveyors have to wind through narrow mineshafts, machines need feeding from above, and every new purchase means deciding what gets torn down to make room. Rebuilding is half the fun: instead of locking in one layout, you keep reworking the whole operation as new machines unlock and old designs stop fitting. Off in the dark there are hidden passages and rooms with treasure, plus abandoned mining operations to pick apart for parts. It is unhurried and self-paced, with goals to chase but no timer breathing down your neck.
