Liar's dice is a class of dice games for two or more players in which deception is a significant gameplay element. In "single hand" liar's dice games, each player is given a set of dice, all players roll once, and the bids relate to the dice each player can see plus all the concealed dice. In "common hand" games, there is one set of dice which is passed from player to player. The bids relate to the dice as they are in front of the bidder after selected dice have been re-rolled. Originating during the 15th century, the game subsequently spread to Latin American and European countries. In 1993, a variant, Call My Bluff, won the Spiel des Jahres.
