How many cards do you get in Rummy?

Ten each with two players, seven each with three or four. The rest of the deck becomes the stock, with one card turned face up to start the discard pile.

Can I lay off cards on another player’s melds?

Yes. Once a meld is on the table it no longer belongs to anyone, so any player may extend it. You can lay off even in a turn where you put down no melds of your own.

Shedding your entire hand in a single turn, having never melded or laid off earlier in the game. It doubles your score for the round, which makes it tempting and genuinely risky.

What score do you play to?

It depends on the number of players: 100 points for two, 150 for three and 200 for four. Only the winner of each round scores, taking the value of all the cards their opponents are still holding.

What happens if the deck runs out?

The discard pile is shuffled to form a new stock. If the stock is exhausted a second time, the hand ends in a stalemate and nobody scores anything.

Do aces count high or low?

Low. An ace can start a run as A-2-3 but cannot finish one as Q-K-A, and runs never wrap around. As deadwood an ace is worth just 1 point.

Rummy

Rummy is the plain ancestor of a very large family. There is no crib, no trump, no bidding and no partner — just the constant small question of whether to keep a card or let it go.

Draw a card, put down any melds you can, lay off on melds already down, then discard to end your turn.

How to play Rummy

With two players each gets ten cards; with three or four, seven each. The remaining deck goes face down as the stock with one card turned up to start the discard pile. Play passes to the left.

Your turn, in order

Draw one card, from either the stock or the top of the discard pile.
Meld if you can. A set is three or four cards of the same rank; a run is three or more consecutive cards in one suit, aces low, no wrapping. You may put down as many melds as you like in a single turn.
Lay off any cards that extend melds already on the table — anyone's melds. Once a meld is down it belongs to nobody, so if there is a run of 5-6-7 of hearts in front of your opponent and you hold the eight of hearts, you can attach it. You may lay off freely, even in a turn where you melded nothing yourself.
Discard one card to finish. If you drew from the discard pile, you cannot throw that same card back this turn.

Ending the round

The round ends when a player gets rid of every card. Usually that means discarding your last card face down, but you are not obliged to end on a discard: if you can meld and lay off your entire hand in one turn, you win there and then.

If the stock runs out before anyone finishes, the discard pile is shuffled and becomes a new stock. If it runs out a second time, the hand is a stalemate and nobody scores.

Scoring

Scoring is winner-takes-all. The winner adds up the cards left in every opponent's hand and takes that total: face cards 10, aces 1, everything else face value. The target depends on the player count — 100 points for two players, 150 for three, 200 for four.

Going rummy doubles your score for the round: it means shedding your entire hand in a single turn having never melded or laid off earlier in the game. It is a real gamble, since you carry a full hand of points for a long time.

Strategy

Rummy is the most forgiving game in its family, which means the mistakes are subtle rather than punishing.

Meld early — the points are in your hand, not on the table

Because scoring counts only what you are still holding when someone else goes out, cards on the table are safe and cards in your hand are a liability. New players hoard melds hoping to go rummy and then get caught holding thirty points. Unless you are deliberately going for the double, put things down as soon as they are legal.

Watch what the discard pile is telling everyone

Taking a card from the discard pile is public information: everyone now knows roughly what you are collecting. Take from the stock when you can afford to, and when you must take a discard, expect the table to stop feeding that rank and suit.

Do not extend an opponent’s meld for the sake of it

Laying off is how you shed cards, but every card you attach to a meld is also a card you have removed from your own future options. If the eight of hearts might complete a run of your own in two draws, holding it one more turn is often correct.

Keep cards with two possible homes

A seven that could join a set of sevens or a run in its suit is worth two ordinary cards. When choosing a discard, throw the card with the fewest ways of becoming useful, not simply the highest one.

Only go rummy when the hand is nearly complete already

Doubling your score is attractive and the requirement is strict: nothing melded, nothing laid off, then everything at once. Attempt it only when you can see the whole hand coming together, because being caught mid-attempt hands the round to someone else with your entire hand counting against you.

Variants

500 Rum — everyone scores their own melds positively and their remaining hand negatively, played to 500. It rewards steady melding rather than a single win.
Gin Rummy — the strict two-player version with knocking and deadwood scoring instead of melding onto the table.
Contract Rummy — a fixed sequence of required melds each hand, getting harder as the game goes on.
Indian Rummy — thirteen cards, two decks, jokers as wild, and a requirement for a pure run before you can go out.
Rummy 500 house rules — many tables allow drawing more than one card from the discard pile provided you use the lowest one taken.

Where Rummy came from

Rummy's ancestry is genuinely disputed. The two leading candidates are the Chinese game Khanhoo — a draw-and-discard melding game documented in the nineteenth century and closely related to the tile game that became Mahjong — and the Mexican Conquian, described in Spanish-language sources and reaching the American Southwest in the same period. David Parlett examines both lines in his history of card games and treats Conquian as the more direct ancestor of the Western rummy family.

Whatever the source, the family exploded in the United States in the twentieth century. The draw-and-discard structure turned out to be enormously adaptable, and it produced Gin Rummy in 1909, the 500 Rum family in the 1920s, and then Canasta, which arrived from Uruguay and became such a phenomenon in the early 1950s that it briefly outsold every other card game in America. Basic Rummy survived all of it as the version people teach children, which is roughly the role it still plays.
