In "Did you know...?", players aim to get to know each other better by asking and answering questions from themed cards. At the beginning of the game, players collectively decide which categories of themed cards will be used. Each player is then dealt a hand of cards and must complete specific tasks to earn the right to draw and ask questions from these themed cards. Tasks are determined by task cards drawn at the start of each round. Players take turns drawing cards and attempting to fulfill the tasks. The first player to complete a task draws a themed card and asks a question, which everyone answers. The game continues until a player collects the required number of themed cards to win, with the number of cards needed depending on the number of players.
