Forming sets and runs from a hand of cards is the fundamental element of the game of rummy. Three or four cards of the same rank but different suits make up atypes of slots set, whereas three or more cards in the same suit make up a run. While minimizing the number of points remaining in your hand after another player leaves, the goal is to merge your cards into these combinations. The draw pile is made up of the remaining cards after each player is dealt a certain number of cards.
