Rummy hand validator: check if your declaration is valid
Check your 13-card hand with RummyDen’s table-hint logic and learn which sequences or sets are missing. Your room’s server makes the final decision.
Paste a 13-card Indian Rummy hand below and this checker tells you instantly whether it is a valid declaration — and if not, exactly what is missing. It runs the same client-side group checks used for table hints on RummyDen. The live server makes the final decision using your room's rules. Check the 13 cards left after your final discard.
Printed jokers (type JK) are always wild. If a card was cut to pick the wild rank, choose it here.
Card format: rank + suit, e.g. AS (Ace of Spades), 10H, KD. Suits: S H D C. Use JK for a printed joker. Separate cards with spaces, groups with new lines.
Enter a hand above to check it.

Example checks
Three hands from our declaration guide, with the labels this checker gives them. None uses a wild rank or a printed joker, and the first two are also on the buttons above.
Two pure sequences and two sets
✓ Valid declaration
13 cards: two pure sequences and two sets. Every card belongs to a valid group.
Four sets, no sequences
✗ Not a valid declaration
All 13 cards form sets, but there is no pure sequence and no second sequence. Zero deadwood does not make a valid declaration.
A set repeats a suit
✗ Not a valid declaration
13 cards and two sequences, but QH QH QC is not a set: natural cards in a set must have different suits, even in a two-deck game.
What counts as a valid declaration?
In 13-card Indian Rummy you win by arranging all 13 cards into valid sequences and sets, then declaring. A declaration is only valid if it meets every one of these rules:
- At least one pure sequence — three or more consecutive cards of the same suit with no joker. Without one, you cannot make a valid declaration. Submitting an invalid declaration receives the room's full-cap penalty; a losing hand that was not declared is scored separately. See our pure sequence guide.
- At least two sequences total — the second (and any others) can be impure, i.e. use a joker.
- Every card grouped — the remaining cards must form valid sets or sequences, leaving zero ungrouped "deadwood".
- Valid groups only — a sequence is same-suit consecutive; a set is 3–4 cards of the same rank in different suits. Jokers can stand in for missing cards in impure sequences and sets.
How to read the result
The checker labels each line as a pure sequence, impure sequence, set, or invalid, then gives an overall verdict. If it says "not valid", the reasons list tells you exactly what to fix — usually a missing pure sequence, only one sequence, an invalid group, or leftover deadwood. Curious how those leftover cards are counted when you lose a round? Our rummy scoring guide breaks it down.
The three mistakes this checker catches most
In 2,259 real rounds on RummyDen, about one declaration in twelve was invalid and cost the declarer 80 points. Almost nine in ten of those came down to three mistakes — all of which this checker flags before you commit:
- No pure sequence (a third of invalid declarations). Every other group can be perfect; without one run that uses no joker at all, the hand cannot be declared. Remember that on RummyDen a wild-rank card counts as a joker even in its natural place.
- Only one sequence (just under 30%). A pure sequence plus three sets groups all 13 cards, but the rules need a second sequence — pure or impure.
- One broken group (a quarter). Most often a set that repeats a suit, which is easy to do with two decks, or a run with a gap no joker fills.
