In World Class Liar, players try to be first to score in each of four languages. Rounds are played by discarding cards to the table face down and calling the number of cards and the language. Opponents can call 'liar' in the language of the cards being played, or play can continue to the next player who must also try discard in the same language.
To score a language a player must discard his last cards face up to the table.
There are partnership rules included as well.
