Rummy games first appeared in the early twentieth century, and are probably derived from the Mexican game Conquian. The object of the game is to dispose of all the cards in your hand. There are three ways to get rid of cards: melding, laying off, and discarding. Melding is taking a combination of cards from your hand, and placing it face up in front of you on the table, where it stays. There are two kinds of combination which can be melded: sequences (also known as runs) and groups (also known as sets or books). Laying off is adding a card or cards from your hand to a meld already on the table.Discarding is playing a card from your hand on top of the discard pile. You get rid of one card this way at the end of each turn. Various options are here available to select, including the number of opponents, decks and scoring.
