Which are the most spoken languages in the world? The most commonly traded currencies? The countries with most Olympic medals? 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.
