2-6 players - 1 pack (52)
If two play, ten each; three or four receive seven each; five or six receive six each. Deal cards face down and one at a time. Place the remainder face down to form a stock. Take the top card of stock and place it face up on the table to start the discard pile.
To go out by laying down melds of three or more cards at a time. A meld is a group of cards of the same rank, or a sequence in the same suit, for which purpose Ace is low (A-2-3 only). If not the first to go out, a secondary object is to reduce the total face values of cards left in hand. In this respect Ace counts one and court cards ten each.
Each in turn must (a) draw the top card of either the stock or the discard pile and add it to his hand; (b) meld or lay off one or more cards if able and willing to do so; then (c) discard one card face up to the discard pile. A player who has drawn the top discard must discard something different.
MELDING AND LAYING OFF
One or more melds and/or lay-offs may be made at the same time. A meld is placed face up on the table in front of the player making it. A card that extends any meld on the table may be laid off against that meld regardless of who made it. For example, an Ace may be played to a meld of A-AA, or Five and Nine of Hearts to a meld of Six, Seven and Eight of Hearts.
END OF STOCK
It may happen that no one goes out before the stock has been exhausted. If there are no cards in stock for the player in turn to draw from, he may either take the top discard in the normal way, or turn the discard pile upside down to form a new stock, in which case he must continue his turn by drawing the top card of it.
The winner is the player who goes out by playing the last card from his hand, whether by melding, laying off or discarding. The game immediately ends, and each opponent pays the winner an amount equivalent to the combined face values of all the cards left in his hand (or the winner scores an equivalent amount).
A player goes rummy by getting rid of his entire hand in one turn, by any combination of melding, laying off and discarding, but without having melded or laid off a single card in the current deal. In this event he receives or scores double against each opponent.
A game may consist of any agreed number of deals or be played up to a previously agreed target score.
