Codenames is a brilliant team activity. Two spymasters try to get their teams to guess specific words on a grid. You give a one-word clue that connects multiple cards. Your team debates what you meant. Sometimes they connect things in ways you never intended. It gets loud and people will argue about definitions. There is always a risk of hitting the assassin card and losing instantly. It scales well to large groups. You can teach it in two minutes. Highly replayable and a mandatory addition for anyone who hosts game nights.
