Three or four cards of the same rank but different suits make up a set, whereas three or more cards of the same suit in a row make up a run. To lower the total value of unmelded cards in your hand, the goal is only rummyto meld these combinations before your opponents do. A predetermined number of cards are dealt to each player, and the remaining cards are arranged in a draw pile. In order to improve their hands while monitoring the moves of their opponents, players alternately draw from the draw pile or the discard pile. The specific variation of Rummy being played—such as Gin Rummy, Indian Rummy, or Kalooki—can affect the rules.
