The goal of Gin Rummy is to minimize the value of unmelded cards in the hands of players while forming sets & runs. When one player "goes gin"—that is, melds every cardind slots all in their deck—or "knocks"—that is, when they have a small number of unmelded cards—the game is over. Indian Rummy is another well-liked variation that uses two decks of cards & uses jokers as wild cards. Players in Indian Rummy are required to form a minimum of two sequences, one of which needs to be pure (i.e., devoid of a joker).
