A run is a series of three or more cards in the same suit, whereas a set is made up of three or four cards of the same rank but different suits. The rummy bonus 100game can be played with two or more players, & depending on the version being played—for example, Gin Rummy, Indian Rummy, or Kalooki—the rules may differ slightly. A certain number of cards—usually seven or ten, depending on the variation—are dealt to each player at the start of the Rummy game.
