Build a branching scenario
A scenario puts the learner in a situation: someone speaks, the learner chooses what to say or do, and their choice leads to the next scene. Some endings are the outcome you want; reaching one of those can complete the lesson.

Write a scenario
Section titled “Write a scenario”Add the block
In a lesson, type / and pick Scenario. It starts with two scenes: an opening scene with one choice, and an ending.
Write each scene
For each scene, fill in Who speaks (for example, Dana, the customer), What happens or is said, and a picture if you want one. Name (only you see it) helps you find the scene when you link choices.
Add the choices
Select Add a choice, write What the learner says or does, and choose where it leads: an existing scene, or A new scene. Feedback after this choice shows before the next scene, if you write some.
Mark the endings
A scene with no choices is an ending. Tick Reaching this ending completes the scenario on the endings you want learners to reach.
Decide whether it's required
Tick Learners must reach an ending that completes it to finish the lesson if the lesson should wait for it.

Starts with sets the first scene. Choices can lead back to an earlier scene, so learners can try again inside the scenario.
Before you publish
Section titled “Before you publish”While you write, the block lists what Publish will ask you to fix:
- a choice that doesn’t lead to a scene, or has no text;
- a scene no choice leads to;
- no ending (a scene with no choices);
- a required scenario with no ending that completes it.
What learners see
Section titled “What learners see”Learners read each scene and pick a choice. After a choice with feedback they see what they chose and the feedback, then Continue. At an ending, the scenario says whether it’s the ending that completes it; at any ending they can Start again.
When a required scenario reaches a completing ending, the lesson is complete. Sessionboard checks the learner’s choices against the published scenario, so a lesson is only completed by a real path to that ending.
