Rummy is a group of games related by the feature of matching cards of the same rank or sequence and same suit. The basic goal in any form of rummy is to build melds which can be either sets (three or four of a kind of the same rank) or runs (three or more sequential cards of the same suit) and either be first to go out or to amass more points than the opposition.
Origin There are two common theories about the origin of rummy, attributing its origins in either Mexico or China in the nineteenth century.[1] The first is that it originated in Mexico around the 1890s in a game described as Conquian in R.F. Foster's book Foster's Complete Hoyle, which was played with a 40 card Spanish deck and had melding mechanics. The second is that Rummy originated in Asia, and that Rummy was the result of a Mahjong variant named Kun P'ai that was Westernized as Khanhoo by W.H. Wilkinson in 1891.
Games scholar David Parlett combines these two theories, and proposes that the Mexican game of Conquian, first attested in 1852,[2] is ancestral to all rummy games, and that Conquian is the equivalent of the Chinese game Khanhoo.[3] The rummy principle of drawing and discarding with a view to melding appears in Chinese card games at least in the early 19th century, and perhaps as early as the 18th century.[4] Rummy variations like Gin and Canasta became popular in the twentieth century. Rummy games are popular in India, and it is likely that Indian rummy is an extension of gin rummy and 500 rum, which originated from the United States. Several theories about the origin of the name "rummy" exist.[5] Some attribute it to the British slang word rum, meaning odd, strange, or queer. Others say the origin lies in the game Rum Poker, or in the popular liquor of the same name.
Deal Depending on the variation, each player receives a certain number of cards from either a standard deck of 52 cards, more than one deck or a special deck of cards used for specific games. The un-dealt cards are placed in a face down stack in the middle, which is known as the stock. In most variations, a single card is turned face up next to the stock where players discard or shed cards, and this is known as the discard pile. In 10 Cards Rummy, which is often played with two, three or four players, each player gets ten cards. In rummy games with five players, each player is given six cards. In 500 Rummy, each player is given seven cards. In Indian Rummy, 13 cards are dealt to each player. Melds A meld can either be a set (also known as a book) or a run. A set consists of at least three cards of the same rank, for example 4♥ 4♦ 4♠ or K♥ K♦ K♠ K♣. A run consists of at least three consecutive cards of the same suit J♣ Q♣ K♣ or 4♥ 5♥ 6♥ 7♥. Very few variations allow runs that have mixed suits. In a few variations of rummy, other patterns may be allowed. In some variations the melds (sets and runs) must be 3 or 4 cards, while other variations allow larger melds through the use of longer runs, for example: 8♠ 9♠ 10♠ J♠ Q♠ or, if multiple decks or wild cards are used, 5♦ 5♣ 5♥ 5♠ J or Q♥ Q♦ Q♣ J. Wild cards (such as a joker) may be used to represent any card in a meld. The number of wild cards in a meld may be restricted. Play Depending on the variation of the game, players take turns adding and shedding cards from their hands. There are numerous and quite different ways of doing this though it usually involves picking a card from the stock and discarding a card to the discard pile. In some variations melds are revealed to all players by placing them face up on the table, in other variations players keep their hands hidden until the show. Some variations permit picking up the entire discard pile. A few variations permit stealing cards from their opponents melds. Show In most variations players must put all their cards into at least two melds (though they may be allowed to shed one card to the discard pile before showing). A player who has melded all cards reveals those still held and submits them for validation. All other players reveal their melds and deadweight. The action of submitting the cards is called Showing. Scoring After a successful show, the winner or all players score their hands. In most variations numbered cards have certain assigned points and the royal cards (J-Q-K) have assigned points and the A often has a different point value. Scoring often involves each player adding up points in their melded cards (sets and runs) and deducting points from cards that have not been melded. The winner may also receive a bonus for winning. Some special or difficult melds may also give extra points to a hand. A player may have a negative score if unmelded cards total more than melded ones. Usually play continues until one player passes a threshold, for example 1,000 points.
