How to Play This Icebreaker Game

1Secretly select one person to be the detective and have them leave the room (or virtual space).
2The rest of the group agrees on a rule for answering questions. For example, 'Always answer as the person to your right would'.
3The detective returns and can ask yes/no questions to anyone in the group.
4The detective's goal is to deduce the secret rule by noticing the pattern in the answers.

Variations

Physical Clue: Add a prop or action everyone must include (e.g., 'tap your nose before answering').
Opposite Day: Group answers opposite of what they'd normally say.
Chain Rule: 'Answer as if you're the person who spoke before you.'
