Rummy offers a wide variety of variants to suit a range of tastes & ability levels. Gin Rummy, Indian Rummy, and Kalooki are a few of the most well-liked variations; each has its own set of guidelinesatta king openings and strategies. Usually played between two players, Gin Rummy places a strong emphasis on making melds as fast as possible while reducing deadwood, or the number of unmatched cards that remain in play at the end of a round. However, to add another level of complexity, Indian Rummy frequently uses two decks of cards and requires players to form at least two sequences before declaring victory.
