A persistent, remote game engine is hosted at shade.tacc.utexas.edu on port 8432. Using the diplomacy client, you can connect and launch games remotely (i.e. from your local machine, program JupyterHub, or compute nodes on TACC systems, etc.). The game engine source code is pulled directly from the SHADE Github.
Quickstart material can be found here.
