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 granted to players through the use of different APIs:

  • CharSheet -- A simple and easily customizable script allowing players to create their own character sheets, using the command !charsheet
  • -- Enables players to reveal/hide Dynamic Lighting sections such as doors. The GM can change doors from between locked/unlocked to adjust which doors the players can open. Speeds up DL management for GM as well.
    • can be used for revealing hidden door
    • v1.211 Introduces option to create "windows", sections that stop movement but not sight. GitHubLogo.png
  • emas -- Provides player !emas and !as commands. This is equvivalent to the /emas, which is GM-only
  • MapChange -- has option to allow players to move between map pages, and GM can choose which pages are available/visible to them
  • -- handy way to add/remove players as "Observer", who can see & control all player characters.
  • — create public, read-only versions of character sheets
  • Roll20 Audio Master (aka. Roll20AM) -- API commands to manage the u Jukebox, GM can grant selective access to individual players/tracks
  • Teleport -- provides a way for GMs or players to teleport tokens within,or between, map pages
  • TokenMod -- For managing token properties with chat commands. Usually players have limited control of their token settings, apart from editing the three bubbles.
    • Includes setting that enables players to target tokens they don't control

There are also API that can be used to restrict players more that normal:

  • – An API that can stop players from drawing on the map, deleting any drawing instantly.
  • TokenLock – Allows GMs to lock/unlock the movement of all Player Tokens. - Useful for when you want to pause the situation and prevent players from accidentally moving forward.
  • MapLock - similar to TokenMod, but can be used for locking down any individual graphic/token on the map, so even the GM can't accidentally move things.
    • Useful if you want players to have control over a token otherwise(see stats, edit/see name & notes), but stop it form being moved.


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
