Rummy is a group of matching card games notable for similar gameplay based on matching cards of the same rank or sequence and same suit. The basic goal in any form of rummy is to build melds which consists of sets, three or four of a kind of the same rank; or runs, three or more cards in sequence, of the same suit. You can also have mixed runs in all types of rummy so long as all 7 cards are in order. The original form of rummy is called Sai rummy, Straight Rummy, Standard Rummy, Traditional Rummy, or Basic rummy.
