Big two (also known as deuces and various other names), is a card game of Chinese origin.
 It is similar to the games of president, crazy eights, cheat, winner, and other shedding games.
 The game is very popular in East Asia and South East Asia, especially throughout China, Indonesia, Macau, Hong Kong, Malaysia and Singapore.
 It is played both casually and as a gambling game.
 It is usually played with two to four players, the entire deck being dealt out in either case (or sometimes with only 13 cards per player, if there are less than four players).
 The objective of the game is to be the first to play of all of his cards.
 It is sometimes confused with "tien len" (a.k.a. thirteen); the two games differ primarily in that big two involves poker hands, while "tien len" does not.
Pusoy dos (or Filipino poker, also known as chikicha or sikitcha), a variation of big two, is a popular type of "shedding" card game with origins in the Philippines.
 The object of the game is to be the first to discard one's hand by playing them to the table.
 If one cannot be first to play all cards, then the aim is to have as few cards as possible.
 Cards can be played separately or in certain combinations using poker hand rankings.
 Games of Pusoy Dos can be played by three or four people.
