Spyfall

Play now ⏩

Welcome, Agent!

You're a detective, but someone in your department is an enemy spy. Everyone is invited to a social gathering. Everyone but the spy has gotten the invitation.

Your job is it to discover which player is the spy and save the integrity of you whole organisation.

Instructions

What you will need
Player count	4-12 players
Player location	in the same room or zoom call
Time	6-10 minutes: the smaller the group, the shorter the time

How to win
Spy	Try to guess the round's location by the agents' questions and answers.
Agents	Figure out who the spy is.

How to play

• The location: At the start of each round, a location of the gathering is chosen. The location is the same for all players except for the spy. The spy is randomly selected and given a blank "spy" card, so he/she won't know the round's location.
• Questioning: The game leader (organizer or the spy of the previous round) start by questioning another player about the location. Example: "Do you think I can bring my partner?"
• Answering: The questioned player must answer. Follow-up questions are not allowed. The answer should be specific enough to convince the other players that questioned player knows the location, but vague enough so the spy cannot infer the location from the answer. After the answer, the questioned player gets to ask another question.
• No retaliation: It is not allowed to pose a question to a player who just interrogated you! You must choose someone else.

The game ends...

There are 3 ways the round can end:

1. No time left: When the clock runs out, the spy remains undercover and wins the round. He/She can now reveal himself/herself.
2. Spy guess: If at any point during the round the spy is certain to have found out the round's location, the spy can reveal his/her role and guess the location. If the spy is right, he/she won the round, otherwise the round is lost!
3. Indictment: The players can indict another player in a unanimous vote. If they cannot come to an agreement (all but one players vote for a suspected spy), the questioning goes on. If they vote out a player, who is not the spy, the spy wins! An indicted spy loses.

Optional rule: An indicted spy can still win if he/she has found out the location.
