# Room Simulators

Simulators per room can be enabled in the dashboard for the project. The Simulator used is matched according to the [Simulator slug](https://docs.coherence.io/manual/simulation-server/simulator-slugs) in the RuntimeSettings scriptable object file. This is set automatically when you upload a Simulator.

For each new Room, a Simulator will be created with the command line parameters described in the [Simulators](https://docs.coherence.io/manual/simulation-server/..#command-line-parameters-in-the-cloud) section. The Simulator is shutdown automatically when the Room is closed.
