Liar's Dice

Liar's dice is a class of dice games for two or more players. The games are easy to learn, require little equipment, and can be played as gambling or drinking games. Playing them well requires the ability to deceive and detect an opponent's deception. The genre has its roots in South America, with games there being known as Dudo, Cachito, or Perudo; other names include "deception dice" and "diception."

In "common hand" liar's dice games, each player has a set of dice, all players roll once, and the bids relate to the dice each player can see (their hand) plus all the concealed dice (the other players' hands). In "individual 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. The drinking game version is sometimes called Mexicali or Mexican in the United States; the latter term may be a corruption of Mäxchen ("Little Max"), the name by which a similar game, Mia, is known in Germany, while Liar's dice is known in Germany as Bluff.

It was brought to Spain by the Francisco Pizarro during the 16th century.
