Which countries have the largest desert areas in the world? Which animals most commonly appear as last names? Which are the most common chemical elements in the universe? In QUIZehn, each round a new Top 10 category is revealed and, one by one, you have to guess something that appears on the list. If you don't know any answers, you can pass - or keep a straight face and say something believable. Or challenge other players' answers. If you challenge a correct answer, or someone catches you bluffing, you lose a life. When someone is correctly challenged, the challenger gains the card. If everyone but one player passes, that player gains the card. First player to four points (or last player standing) wins the game.
