Welcome to the help site
This is the GreenCloth Games help site. A TV or monitor is the game table, the display. Every player’s phone is a controller. Together they form a party: one shared game session, one table, several hands.
The player manuals are here: the Controller manual for what you do on your phone, the Display manual for what the shared screen shows. If you are making a game of your own, the Builder manual covers the editor, from the first set to a released version.
