Spyfall is a social deduction game where players take on the roles of secret agents and one player is the spy. The game is set in various locations, such as a casino or a beach, and players must ask each other questions to determine who the spy is while the spy tries to blend in and guess the location. Each round lasts about 8 minutes, and players take turns asking questions. The goal for the agents is to identify the spy before time runs out, while the spy aims to gather enough information to guess the location. The game encourages creativity and strategic thinking.
