Players in Gin Rummy can knock when they think they have a sufficient number of deadwood cards, which adds an interesting strategic element as they balance the benefits and drawbacks of ending a round early. Indian Rummy, which is frequently played with two decks of cards and requires plonline skill slotsayers to form at least two sequences—one of which must be a pure sequence devoid of jokers—is another noteworthy variation. By using jokers as wild cards, this version adds complexity while giving players more options for how to construct melds. Canasta, which adds special scoring rules and requires players to form melds with particular card combinations, and Kalooki, which combines aspects of traditional Rummy and poker, are two more variations. Since each variation presents a unique set of obstacles & tactics, fans will find Rummy to be an endlessly captivating game.
