Puzzled Pint Puzzled Pint Puzzled Pint is a monthly, casual, social puzzle solving event. It is held every second Tuesday in 50+ cities around the world, with every location using the same puzzles. The global monthly attendance exceeds 3000. It follows the pattern of a conference-room style puzzle hunt, with teams receiving packets of 4-5 puzzles, usually with the answers feeding into a final Metapuzzle.
