Like Classic Rummy, the goal of the game is for players to form sets and runs using a standard 52-card deck. But what makes Gin Rummy different are the special scorinslots all listg features and gameplay components it offers. After ten cards are dealt to each player, the remaining cards are gathered into a stockpile from which players draw. "Knocking" is one of the most fascinating elements of Gin Rummy. A player may decide to knock if they think their deadwood (unmatched) cards add up to 10 points or less.
