The nodeGame framework allows you to run real-time games and experiments, as well as surveys and other human-intelligence tasks. Learn how on https://nodegame.org.
This app will setup the basic nodeGame server with an ultimatum game.
After creating the droplet, ssh once into your droplet to automatically initialize the nodeGame server.
You can then upload your own game into the server’s games/ directory and restart the server. Instructions will be shown at startup and saved into your home directory.
