Give the lead to someone who likes the spotlight. The leader opens the night and keeps it moving.

Quiet guests get a role with a strong secret: they will be asked, so they never have to push.

Do not cast couples as couples. Playing a stranger is more fun, and nobody knows whose secret is whose.

More guests than roles? Extra roles slot in seamlessly. Nobody can tell who joined last.

Not sure? Deal the roles at random. Every role is built for a good night.
