Traitor Detector
Choose a Traitor behind its back. It will find them — and it will never ask who.
Rule one
Faithfuls cannot lie.
Not about anything.
Traitors cannot tell the truth.
Not about anything.
Rule two
The Detector plays fair.
It will never ask anyone if they are the Traitor.
It will never ask who the Traitor is.
It asks only about the castle, and only what it cannot check.
How should it know you?
Sigils are quicker. Names are personal.
Take your seats
Before anyone is chosen
Two Traitors need a table of five or more.

From now on, the table calls you by it.

Pass the phone along after each name.
The Detector looks away
Phone face down. Count to three, all point at once. Most fingers wins.
Everyone must know. Only the phone doesn't.
From this moment
One of you can no longer tell the Detector a true word. The rest of you can no longer lie — not even to protect them.
Pass the phone when asked. Yes or no. No discussion.
Question 1 of 4
Listening
Interference
A Faithful said something false, or a Traitor said something true.
Traitors lie about other people too. Faithfuls tell the truth about friends too.
