One person is sent out of the room and while they're gone, a story is made up about them. (ie, they got hit by a car while busking in the middle of the road) When they return, the room is set up like a press conference, and all the remaining chanichim are reporters. Their job is to ask the person questions about the story without giving the story away, for example "How were you expecting to make money in that location?". The person has to answer the questions but also accumulate enough knowledge about their actions to guess what they did.
