Rummy terms glossary: every word you'll hear at the table

A plain-English dictionary of the melds, moves, and scoring words that come up in every game of 13-card Indian Rummy.

← All guides

Every card game grows its own vocabulary, and 13-card Indian Rummy has a rich one. The moment you sit at a table you will hear players talk about pure sequences, deadwood, dropping, and declaring, and the words fly fast. This glossary explains every term you are likely to meet, in plain English and in the order they tend to matter during a hand. Keep it open in a second tab the first few times you play, and the chatter will start to make sense quickly.

If you have never played a hand, it helps to skim how to play first, then come back here to firm up the language. For the exact scoring and edge cases, the full rules page is the source of truth.

The building blocks: melds, sequences and sets

Meld

A meld is any valid group of cards you have arranged, either a sequence or a set. Your whole aim in rummy is to organise all 13 cards into valid melds. The word is a catch-all: when someone says they have four melds, they mean four completed groups.

Sequence (run)

A sequence, also called a run, is three or more consecutive cards of the same suit, such as 5-6-7 of hearts. The terms are interchangeable. Sequences come in two flavours, pure and impure, and the difference is the single most important rule in the game.

Pure sequence

A pure sequence is a run of same-suit consecutive cards with no joker helping out, for example 9-10-J of spades. You must have at least one pure sequence to make a valid declaration. Without it, your hand cannot win no matter how tidy everything else looks.

Impure sequence

An impure sequence is a run that uses a joker to stand in for a missing card, such as 4-5-joker of clubs, where the joker plays the role of the 6. It counts as a completed sequence, but it can never satisfy the pure-sequence requirement.

Set

A set is three or four cards of the same rank in different suits, for example three Kings from different suits. All cards in a set must be distinct suits, so you cannot use two Kings of hearts. A joker can complete a set of three, but a four-card set with a joker is usually invalid because the fourth suit is already used up.

Jokers: the flexible cards

Printed joker

The printed joker is the actual joker card that comes in the deck, the one with the jester picture. It can substitute for any card to complete a set or an impure sequence, and it always carries zero points if left in hand at the end.

Wild joker

At the start of each deal, one random card is turned up and its rank becomes the wild joker for that hand. If the 7 of diamonds is flipped, then all four sevens become wild jokers and can substitute for any card, just like the printed joker. Wild jokers change every deal, so always check which rank is wild before you plan your hand.

The table layout: decks and piles

Closed deck

The closed deck is the face-down pile in the centre. You draw from it blind, so you never know what you will get, but your opponents also cannot see what you picked. Most careful players prefer the closed deck to keep their hand a secret.

Open deck (discard pile)

The open deck, or discard pile, is the face-up pile of cards that players have thrown away. You may pick the top card here instead of drawing blind, but everyone sees exactly which card you took, which leaks information about what you are building.

Taking your turn: draw, discard and drop

Discard

To discard is to throw one card onto the open deck at the end of your turn. Every turn is draw one, discard one, so your hand always returns to 13 cards. Choosing what to discard, and reading what opponents discard, is where much of the skill lives.

Drop

To drop is to quit the current hand voluntarily rather than play it out, accepting a fixed penalty instead of risking a bigger loss. A first drop, taken before you have drawn a single card, costs fewer points than a middle drop, taken after you have already started playing. Knowing when to fold a hopeless hand is a core part of good rummy strategy.

Ending the hand: declare, show and scoring

Declare

To declare is to announce that all 13 of your cards are arranged into valid melds. You place your final card face down on a finish slot and lay your hand out for checking. A correct declaration ends the hand and scores you zero, the best possible result.

Wrong show (invalid declaration)

A wrong show is a declaration that turns out to be invalid, most often because a pure sequence is missing or a set repeats a suit. The penalty is steep: the player who made the wrong show is charged the full count, while the round continues for everyone else. Always double-check your melds before you declare.

Deadwood

Deadwood is the collection of cards in your hand that are not part of any valid meld when the round ends. These loose cards are what get counted against you, so reducing deadwood is the whole point of arranging your hand well.

Full count

The full count is the maximum penalty a player can receive in a single deal, capped at 80 points in most house rules. Whether you made a wrong show, ran out the clock without a valid hand, or were caught with a huge pile of deadwood, you will never be charged more than the full count for one deal.

How points add up: card values

Deadwood is scored by the face value of the cards left unmelded. Here is the standard scale.

Formats: pool and deals

Pool

Pool is a game format built around an elimination score, commonly 101 or 201. Points from each hand add to your running total across many hands, and a player is knocked out when their total crosses the pool limit. The last player standing wins the pool. It is the long, tense format where dropping early can save a tournament.

Deals

Deals is a fixed-length format: the group agrees to play a set number of deals, say two or three, and whoever has the fewest total points at the end wins. Because the finish line is known, deals games reward steady, low-risk play rather than dramatic comebacks.

A quick reference cheat sheet

• Pure sequence — same-suit run, no joker; mandatory to win.
• Impure sequence — run completed with a joker.
• Set — same rank, different suits.
• Deadwood — unmelded cards that score against you.
• Drop — quit a hand for a fixed penalty; first drop is cheaper than middle.
• Declare — finish with all 13 cards melded for zero points.
• Wrong show — an invalid declaration, penalised at full count.
