How a Session Flows

If you haven't yet, start with What Is a Tabletop RPG?.

A session moves in a simple loop: the GM frames a scene, players say what they do, the table decides if a check—a die roll to see whether an action succeeds—is needed, and then everyone reacts to the results. Repeat until the story shifts.

What you'll learn

  • The table loop you'll see again and again.
  • When a check happens and when it doesn't.
  • How turn and order keep things fair.

Core idea

  1. Frame: The GM describes where you are and what's at stake.
  2. Act: A player takes a turn—a moment when one player acts and resolves outcomes—by describing an action.
  3. Resolve: If the outcome is uncertain and interesting, make a check. The result creates a consequence—what happens after an action, success or failure.
  4. React: The fiction changes. The spotlight moves in a fair order—the sequence in which players act.

Not every moment needs a check. If the action is safe, obvious, or already decided by earlier facts, the GM just says what happens.

Try this (2 minutes)

Pick a mundane task and add tension: "Cross a slick rooftop in the rain before guards arrive." Decide: is a check needed? If yes, note a success consequence and a failure consequence.

Common pitfalls

  • Calling for checks on routine actions—save the rolls for interesting uncertainty.
  • Forgetting to state consequences; players act better when they know what matters.
