What is legal and illegal inside a rummy hand
This is a reference, not a procedure. It defines each term the rules use, names what is legal and what is not, and lists the conditions under which a declaration is valid. Each section stands on its own and can be read out of order.
Term reference
The terms the rules use
Every rules question on this site uses the same vocabulary. The entries below define each term precisely, in the order they appear during a hand.
Deck
A standard 52-card deck, with ranks ace through king in each of four suits. A second deck is added for six or more players; the two decks are kept separate from each other during play.
Jokers are added to the deck in addition to the printed cards. One printed joker is always in the deck. A second wild joker is determined at the deal and varies by table.
Hand
Thirteen cards dealt to each seat. The remainder of the deck forms a closed stock, with one card turned face up to start the discard pile.
The hand is the unit of play. A points rummy hand ends at the show of the first hand. A deals rummy hand ends after the agreed number of hands. A pool rummy hand continues until a player crosses an agreed ceiling.
Draw
The first move of a turn. The player takes one card from the closed stock or the top card of the discard pile. The card becomes part of the player's hand.
Drawing from the discard pile is faster and informs the table about what the player is collecting. Drawing from the stock is slower and does not.
Discard
The second move of a turn. The player places one card from their hand face up on the discard pile. The discard is the only public signal a player makes during a turn.
Discarding a card the table needs is a deliberate move. Discarding a card the table does not need is a discard that costs nothing to the table.
Meld
A grouping of three or more cards that scores as part of a valid show. Three kinds of meld exist: pure sequence, impure sequence and set.
A hand that contains only sets and no sequences is invalid. Sequences are mandatory.
Declaration
The end of the hand. The player arranges all thirteen cards into valid melds and lays them out, face up, on the table.
A declaration is valid only if at least one pure sequence is present. Without a pure sequence, the declaration is invalid and the player is scored as a full hand.
Drop
The player's exit from the hand before declaring. A first drop is made before picking the third card. A middle drop is made after.
The first drop costs less than the middle drop. The exact costs are set by the table and vary by platform.
The pure sequence
What makes a sequence pure
Three numbered points on a single sequence laid on green felt. The pure sequence is the most important meld in the hand, and the one whose presence or absence decides whether a declaration is valid.
Three things that must all be true
- 01 · Same suit
- All three or more cards must belong to the same suit. A run that crosses suits is not a sequence under any variant.
- 02 · Consecutive rank
- The cards must run in order, with no rank skipped. Ace can be low or high by table convention, but cannot wrap from king back to ace.
- 03 · No joker standing in
- Every card in the run must be a printed card of the right suit and rank. A joker used to fill a gap converts the run from pure to impure.
What is illegal
Six things that are not legal inside a rummy hand
The rules are mostly about what is legal. The list of what is illegal is shorter and easier to read.
A sequence cannot cross suits. A run of three cards that includes two suits is not a sequence under any standard ruleset, no matter how close the ranks are. The suit requirement is absolute.
A sequence cannot skip ranks. A run that jumps from a four to a six is missing a five and is not a valid run. A joker standing in for the missing five converts the run to impure and makes it legal, but only if the joker is the only card filling the gap.
A set cannot contain two cards of the same suit. Three or four of a kind in different suits is a set; three of a kind in two suits and a joker is not, because the suit duplication breaks the rank distribution.
A pure sequence cannot contain a joker. The moment a joker fills a slot in a run, the run becomes impure. The pure sequence is defined by the absence of a joker.
A declaration without a pure sequence is invalid. No matter how many sets and impure sequences the hand contains, the declaration fails without a pure sequence, and the player is scored as a full hand.
An ungrouped card at the show is deadwood. Cards that are not part of a sequence or a set are scored against the player in the conventional way, with face cards and tens at ten points, numbered cards at face value, and aces by table rule.
The joker
What a joker can and cannot do
Two jokers are in play in a thirteen-card hand. The rules on how each can be used are precise, and the differences between the printed joker and the wild joker matter at declaration.
The printed joker is always wild. It can stand in for any card of any suit at any rank. There is one printed joker per deck; a second deck adds a second printed joker.
The wild joker is determined by the table from the first face-up card. A common rule is that the wild joker takes the same rank and any suit; some tables make it suit-only. The reader should confirm before play.
A joker can fill one gap in an impure sequence. A joker can stand in for one card in a four-card set, never in a three-card set. The joker cannot do both at once: a single joker used in a sequence cannot also be used in a set.
The two shows
A valid show beside an invalid one
Two groups of cards on the same table, one legal and one illegal. The differences are small in count and large in consequence, because the invalid show is scored as a full hand.
Why one is valid and the other is not
- 01 · The valid show
- Two sequences, at least one of them pure, with the remaining cards arranged into sets. No ungrouped cards are left over. The declaration stands.
- 02 · The invalid show
- Only sets and no sequences, or only impure sequences with no pure sequence, or ungrouped cards left on the table. The declaration fails and the player is scored as a full hand.
- 03 · The cost of getting it wrong
- An invalid show is not a small loss. It is scored at the conventional full-hand value, which is the same penalty as if the player had never grouped a card. The exact maximum is set by the table.
How scoring works
The conventional scoring approach
Scoring in a thirteen-card hand is conventional rather than uniform. The numbers below are the conventions in widespread use, not the rules of any specific table. A reader should always check the table's published scoring before play.
Face cards (king, queen, jack) and tens are scored at ten points each. Numbered cards are scored at face value. Aces are scored at one point or ten points by table convention; the reader should confirm which. Printed jokers and wild jokers are worth zero points unless they are left as ungrouped deadwood at the show, in which case they are scored at the table's face value for the joker.
An invalid declaration is scored as a full hand against the player. The conventional maximum hand penalty is eighty points, which is the total of all thirteen cards scored at the highest face value. Some tables set a different ceiling. The desk has not verified the exact ceiling at any specific table.
A first drop, made before the third card is drawn, is scored at a small fixed penalty, conventionally twenty points. A middle drop, made after the third card, is scored at a larger fixed penalty, conventionally forty points. The exact numbers vary by table.
A winner is the player with no deadwood at the show. The winner collects points from the losers according to the value of their deadwood, plus any drop penalties they incurred. In some variants the winner also collects a fixed game fee; the desk does not state a figure for any specific operator.
The declaration
What a full declaration looks like
A complete thirteen-card hand arranged into declared groups. Every card belongs to exactly one group, and at least one of the sequence groups is pure.
Three requirements for a valid declaration
- 01 · At least one pure sequence
- Mandatory. The hand cannot be declared without a pure sequence. An impure sequence does not satisfy this requirement on its own.
- 02 · A second sequence, pure or impure
- Required in most variants. The second sequence can be impure, with a joker filling one gap, provided a pure sequence already exists.
- 03 · Everything else in groups
- The remaining cards must be arranged into sets or sequences. Ungrouped cards are deadwood and are scored against the player in the conventional way.
Rules questions
Rules questions readers ask most
Short answers that link to the longer treatment. Where the honest answer is that the desk does not know, that is the answer given.
How many sequences must a hand contain?
At least two sequences, of which at least one must be a pure sequence. The second sequence can be impure. A hand with only one sequence and several sets is invalid.
Sets do not substitute for the second sequence.
Can a joker stand in for any card?
In a sequence, a joker can stand in for one missing card of the same suit, in the correct rank slot. In a four-card set, a joker can stand in for one of the four ranks.
A joker cannot be used as two cards at once, and it cannot stand in for a card in a pure sequence; doing so converts the sequence to impure.
Is an ace a one or an eleven?
By table convention. The most common convention is one point for scoring and either low or high in a run. Some tables allow ace low only, others allow ace high only, others allow both.
A reader should confirm the table's rule before play, because the ace's position changes which runs are valid.
What happens if a player declares with an invalid hand?
The declaration is invalid. The player is scored as a full hand against them. The conventional maximum hand penalty is eighty points.
The exact ceiling is set by the table. A reader who is uncertain about a show should drop rather than declare.
Can the same card appear in two melds?
No. Every card belongs to exactly one meld. A card that sits in two groups is not legally grouped; the declaration fails on that hand.
The reader should lay the cards out on the table before declaring, to make sure each card is in exactly one group.

Before declaring
Four checks before a declaration is made
An invalid declaration costs a full hand. The four checks below take a few seconds and remove the most common reasons for failing a show.
- Is at least one of your sequences a pure sequence, with no joker standing in for any card?
- Is your second sequence valid as pure or impure, with a joker filling only one missing rank?
- Is every card in the hand part of exactly one meld, with no card duplicated between groups?
- If any answer is no, have you dropped, rather than declared, before the cost of a full-hand loss?
