Lecture Bingo - How to Play Click the "Get New Card" button until you get a bingo card you're happy with. Print it out and bring it to any lecture series (works best with some friends who do the same). Whenever something on a square happens, mark it off. First to form a straight line (horizontal, vertical or diagonal) or all four corners, and shout "BINGO!", wins! Inspired by Seminar Bingo from PHD Comics.
