Taking turns, players try to create valid combinations by drawing from the stockpile or the discard pile. Gin Rummy's scoring system is what makes it special; when a player knocks or "gins"—that is, melds all of their cards without 568 slots apkany unmatched ones—points are awarded based on the number of unmatched cards that remain in their opponent's hand. Players are forced to carefully consider when to knock & how to effectively manage their hands, which adds another layer of strategy to the scoring mechanism. In India & among Indian communities around the world, Indian Rummy is a popular variation of the game. This variation can accommodate two to six players and usually uses two decks of cards.
