For example, a player may lay down a single card (e.g. ) on either a set that has already been laid down (e.g. ), or a run or part of a run that has already been laid down (e.g. or ). A player may also lay down a pair of cards in sequence of the same suit on a run or part of a run that has already been laid down (e.g. lay down the on a run of or previously laid down). Cards that are laid down or laid off are kept spread out on the table in front of the player, visible to other players. The player ends his turn by discarding a single card from his hand to the discard pile. Players are usually only permitted to lay down cards when it is their turn, after drawing but before discarding. In a variation, players may put down melds or matching cards on other people's turns. The round is not over until one of the players puts down their last card, so with this variation a player can put down a meld when ever they want, until that last card is down. If jokers are used in the game, they are treated as wild cards and can represent any card the player chooses even if that card is already used in another meld. The round is over when one player has no cards in his or her hand, either by melding or laying off all cards, or when there are no cards left in the stock pile. Players typically receive no bonus for finishing first. Discarding When picking up from the discard pile you cannot pick up just to play a single card on a meld or other cards that have already been laid down, sometimes referred to as "picking up to hit". You may only pick up from the discard pile if you were to put down a meld consisting of 3 or more cards including the card that was picked up. In one variation, a player may pick up from the discard pile to play a single card or pair of cards on a meld or other cards that have already been laid down by any of the players. In another variation, a player may pick up only the top card from the discard pile and keep it in their hand without immediately playing it. Scoring
