Gather together. It's best to be on a call beforehand. Let the most responsible player create a game, and the rest can join using the room code.
You will be asked three questions about yourself. Answer honestly or at least plausibly, without discussing them with other players. One of you is the spy.
Your questions are different from the others'. They share a similar structure (e.g., answering 'How many' or 'Name the date'). Answer carefully and try to blend in as a regular player.
Now all players can see each other’s answers. Identify the spy. You can ask clarifying questions to players who seem suspicious. As the spy, do your best to avoid suspicion.
