A game where a topic is chosen at random. Everyone knows the topic except one person who is the spy. The app prompts a random player to ask another random player a single "yes" or "no" question. Players should formulate the question in a way that it doesn't reveal too much information about the topic but enough to tell if the player who answers is the spy or not. Once each player is done asking their question, they get to vote on who they think the spy is. The spy is revealed afterwards, but he has to guess what the chosen topic was. The phone just organizes the game by picking random topics, choosing which players ask who, and keeps track of the score. You may add your own category of topics.
