The I Should Have Known That! Card Game is a fast-paced, engaging trivia game that flips traditional quizzes upside down. Instead of earning points for correct answers, you lose points for the ones you get wrong — making every question a fun challenge and every mistake unforgettable!
Perfect for parties, family gatherings, and game nights, this game tests your everyday knowledge with questions you *think* you should know… but probably don’t. Expect laughter, facepalms, and competitive energy as players race through quirky general-knowledge questions.
