This is a trivia game, tic tac toe style! Choose a mark (X or O). Then choose your category: Arts & Literature, Food, Geography, History, Movies, Nature, Pop Culture, Science & Math, Sports, or Potpourri. Answer the trivia question. If you get the answer right, you get the box, if not your opponent gets the box. Get three in a row and you win! If the other side gets three in a row, you lose!
