No, you don’t. Cards would make it easy for players to cheat. Instead, Zoom Mafia relies on private messaging to tell players their roles. Cards can be seen if a player decides to open their eyes. Even if it’s by accident, the civilian will have gained an unfair advantage. This is why cards aren’t recommended for Zoom Mafia. Not everyone has playing cards at home either. However, on Zoom, everyone has access to the private messaging system. This makes it all the more relevant and accessible.
