On the Find Games page you will see a Filter called "Game Type" that asks if you are looking to join a one-shot or a campaign. But what do these terms mean?
What is a One-Shot?
A one-shot is self-contained adventure that takes players through a story arc within a single game.
You're only charged one time for a one-shot because it is a single game.
What is a Campaign?
A campaign is a series of connected adventures set in the same world.
The Game Master (GM) will create a backstory, settings, and Non-Player Characters to help the story progress.
You're charged multiple times for a campaign because you and your group will meet multiple times to play together.
