Gin rummy, or simply gin, is a two-player card game variant of rummy. It has enjoyed widespread popularity as both a social and a gambling game, especially during the mid twentieth century, and remains today one of the most widely-played two-player card games.

A card game is any game that uses playing cards as the primary device with which the game is played, whether the cards are of a traditional design or specifically created for the game (proprietary). Countless card games exist, including families of related games. A small number of card games played with traditional decks have formally standardized rules with international tournaments being held, but most are folk games whose rules may vary by region, culture, location or from circle to circle.
