Gin Rummy is one of the most popular forms of rummy. Gin Rummy is generally played by two players each receiving ten cards. Gin Rummy, which evolved from 18th-century Whiskey Poker , was created with the intention of being faster than standard rummy. The objective in Gin Rummy is to score more points than your opponent. The basic Gin Rummy strategy is to improve one's hand by forming melds and eliminating deadwood. In standard Gin Rummy, a player may not knock unless he has 10 or fewer points of deadwood. He must knock, a Gin Rummy term, if he has 0 points of deadwood. Knocking with 0 points of deadwood is known as going Gin or having a Gin, while knocking with deadwood points is known as going down in Gin Rummy.
