round. Game play The object of the game is to score points as in regular rummy by laying down or laying off cards, initially in groups of matching cards known as melds, with a meld consisting of either: 3 or 4 cards of the same rank (e.g. or ) called a set; or in sequences of three or more cards of the same suit (e.g. ) called a run. One variation of the game requires that laying down a run can only be done starting with four or more cards of the same suit (e.g. ). Aces can be played as either a high card or a low card, meaning that they may be played after a king as a high card (e.g. ) or before a two as a low card (e.g. ). Going "around the corner" means that Ace is allowed to be both high and low in the same run (e.g. ). If going around the corner is not allowed, Q-K-A and 2-3-4 must be separate runs. Each player in turn, beginning with the player to the left of the dealer, may draw either the top card of the stock or any card from the discard pile. Once a card is picked up, either from the stock or the discard pile, it is final and no other cards may be picked up. However, there are two conditions when drawing a card from the discard pile: The player must take all the cards on top of (i.e., discarded after) the selected card. The selected card so drawn must immediately be used, either by laying it down in a meld or by laying it off on a meld already on the table if permitted. When drawing a card from the discard pile any remaining cards taken with the card drawn from the discard pile may be either melded in the same turn or simply added to the player's hand. Also, multiple cards picked up from the discard pile are left out until the selected card is played in an acceptable manner. During a player's turn, after drawing but before discarding, they may lay down any meld of matching cards, or may lay off any cards that match a meld or cards that have already been played. A player may lay down a single card or pairs of cards, but only if they match cards that have already been played.
