For larger groups, assign each team a category and give them 60 seconds to answer as many questions as possible. The team with the most correct answers at the end wins. A sign up sheet is a great way to track teams, assign scorekeepers, and sort out who's bringing snacks.
True or false questions are the perfect equalizer. They require no special knowledge, no teams of experts, and no complicated rules, just curiosity, a little confidence, and the willingness to be spectacularly wrong in front of people you like.
Use this list for your next game night, as a classroom warm-up, or to break the ice at a team meeting. Divide into teams and race through a category, appoint one person as host and keep score, or go fully casual and just see who knows the most random things. However you play, these questions cover enough ground that everyone will get a few right, and everyone will get a few wrong.
