Three thirteen is a variation of the card game Rummy. It is an eleven-round game played with two or more players. It requires two decks of cards with the jokers removed. Like other Rummy games, once the hands are dealt, the remainder of the cards are placed face down on the table. The top card from the deck is flipped face up and put beside the deck to start the discard pile.
