Indian Rummy, for example, adds an exciting twist to traditional gameplay by allowing jokers to be used as wild cards and usually involving two decks of cards. Gin Rummy is another well-likteenpatiied variation that is played between two players and places an emphasis on forming runs and sets while reducing deadwood, or unmatched cards. Another variation of Rummy that adds more rules about melds & scoring is called Kalooki, which makes it more intricate than the original. While maintaining the fundamental rules that make Rummy fun, each variation adds a distinct flavor.
