Pressure Works

Pneumatic machine building

Pressure Works is a PC machine-building sandbox built around a pneumatic simulation. You place structural parts on a snapping grid, connect them with hoses, and open valves to send pressure through the network. Cylinders, motors and other mechanisms move only when the pressure and connections make them work, so troubleshooting a stalled machine means checking its plumbing.

Steam and air use the same simulation, with pressure lines serving as both power and control signals. Buttons, directional valves, latches, and AND, OR and NOT valves can form logic circuits for tasks such as timing and sequencing. Regulators, flow restrictors, air tanks and gauges give you ways to control or diagnose the system. Colored light nodes are also available for building a functional computer.
