Three or four cards of the same rank make up a set, whereas three or more cards of the same suit in a row make up a run. When a player successfully melds every card in their satta ka kingdeck—either by laying them down or by discarding their final card after melding—the game is over. There are many variations of Rummy to suit varying tastes & ability levels, though, so there isn't just one. For example, Indian Rummy, which is well-liked in South Asia, usually uses two decks of cards and jokers to enable more intricate gameplay.
