The game of Gin Rummy, for example, is usually played between two players & focuses on making melds as fast as possible while avoiding deadwood, or unmatched cards that can increase your score if your opponent 567goes out. When one player knocks or goes gin, indicating that they have melded all of their cards, the game is over. Players in Indian Rummy, on the other hand, must form at least two sequences, one of which must be a pure sequence (without a joker). Indian Rummy is frequently played with two decks of cards. Players in this variation must sort through more cards and possible melds, which adds complexity & strategy.
