Dive into soft body physics

Rigs of Rods is a sandbox-style vehicle simulator

What makes Rigs of Rods different to most simulators is its unique soft-body physics model: vehicles, machines, objects, etc. are simulated in real-time as flexible soft-body objects, giving the simulation an extremely accurate behavior which entirely depends on the physical construction of the vehicles or objects you create.

Sandbox full of toys

Play with a vast selection of vehicles and terrains


Node and beam simulation with realistic handling and damage - check!


Accurate wheel and rail simulation with derailments on overspeed - also check!


Buoyancy model based on elemental pressure gradients - you got it!


Advanced flight model based on blade element theory - this too!

Entirely Free and Open Source
