On the Campaign Main Page, Bob is shown to be a GM in the campaign by the blue "GM" shown on his icon

Game Masters , or GM for short, are the ones who can control basically all aspect of a Campaign while in-game. The Creator of a game is essentially a GM, but have exclusive access to a number of settings for the Campaign only they can access.

Players have much more limited options on what they can do, than the GM or Creator.



If the Creator of the game is a
info or
info user, the other GM(s) of the game get access to all those tools & features in-game, such as:

A GM can change which API are installed in a game.

Promote player to GM

Promote someone to GM

A GM can promote a Player to GM on the Game Settings-page. Hover your mouse over their icon, and select "Promote to GM". You should see that the player gets a blue "GM" on top of their icon.

A game can have any number of GMs, and multiple people can be logged in as a GM at the same time.

Rejoin as Player

The Creator or a GM can voluntarily disable their GM-status in a game by in-game going to y My Settings-tab, and pressing the Rejoin as Player-button at the top.

By default, you always enter a game as a GM if you are on it's main page, and either have to do the above each time, or you can right-click the Rejoin as Player-button and bookmark it.

Using the bookmark you can you can enter the game directly as a player, avoiding accidentally spoiling yourself something before you have gone to the button.


Some GM-only features can be indirectly be granted to players through using different APIs, such as:

  • emas -- Provides player !emas and !as commands.(emote as)
  • Roll20 Audio Master -- API commands to manage the u Jukebox
  • MapChange -- has option to allow players to control what page they see
  • (don't remember name) -- allows the player to create new character sheets for themselves

There are also API that can limit players more that normal:

  • DryErase – An API that can stop players from drawing on the map, deleting any drawing instantly.
  • TokenLock – Allows GMs to selectively lock the movement of Player Tokens.


Bob is shown as the game creator in the top right corner of the campaign's main page

The Creator of a game has a few things exclusively available to them, which other people promoted to GMs can't do.

This is mostly related to General & Default settings that are accessed in the menus outside the game: Game Management
