How to play thirteen-card rummy in plain language
From the deal to the show, the desk walks the reader through the full sequence — the joker, the drop, the declare, and what an invalid declaration actually costs at the table.
The deal and the joker cut
Thirteen-card rummy starts with a 52-card deck plus one printed joker. Two to six players receive thirteen cards face-down. The next card from the closed deck is placed face-up to start the open pile; the remaining cards stay face-down as the closed pile.
A wild joker is then drawn from the closed deck. The card whose rank matches the printed joker becomes the wild joker for the round. The printed joker is also a wild joker. Either substitutes for the card printed on it — but it cannot replace a card required by a pure sequence.
The first player to act is the player to the dealer's left. They must pick a card from either the closed pile or the open pile, then discard one card face-up to the open pile. Play continues clockwise.
Building a valid hand
A valid declaration needs at least one pure sequence — three or more consecutive cards of the same suit, no jokers used. The hand must also contain either a second pure sequence, or a set of three or four cards of the same rank. The remaining cards can be absorbed into either category.
An impure sequence is a pure sequence with one printed joker substituting for a missing card. It counts toward the declaration but does not replace the requirement for at least one pure sequence.
A set is three or four cards of the same rank across different suits. Jokers can stand in for one missing card in a set. A set cannot be all jokers, and a set of four with a joker counts as a valid four-card group.
The draw and the discard
Each turn has two parts: a draw and a discard. On the draw, the player must take the top card from the closed pile, or the top card from the open pile. Picking up from the closed pile is the only path to the wild joker. On the discard, the player must place one card face-up on the open pile.
Drawing from the closed pile and immediately discarding the same card is a legal sequence only if you have not seen that card's face yet. Some platforms consider this a technical full-count trigger; check the platform's rule page.
The full-count penalty applies when a player reaches for a third card from the closed pile without picking the top discard. The full-count score is 80 points. This is the largest single penalty in the format.
When to drop, when to play
Leave the hand before picking a card. The cheapest penalty and the right move when the dealt hand has no path to a pure sequence.
Leave the hand after picking at least one card but before drawing the 14th card. Mid-strategy exit when the open pile does not help.
Triggered by reaching for a third card from the closed pile without picking the top discard. Equivalent in cost to an invalid declaration.
Declared hand does not hold up at the show — missing pure sequence, missing second sequence, set with conflicting joker rules. Same cost as a full count.
The show and the declare
To declare, the player discards their 14th card face-down onto a meld, then arranges the remaining 13 cards into valid groups for the show. The other players verify the groups at the show. A valid declaration wins the round; the loser pays the points accumulated against them.
If the discarded 14th card would have completed a meld that the player already formed, they may pick it back and form the meld as part of the show. The platform's rule page will tell you whether picking-back is allowed on a discard that did not originally form part of the show.
If the verification fails — for any reason, including a missed card or a wrong joker substitution — the declaration is invalid and scored at 80 points. The desk recommends reading the platform's invalid-declaration rules carefully before your first cash game.
What a reference hand looks like
| Player | Hand type | Penalty type | Score |
|---|---|---|---|
| Anita | Two pure sequences, two sets | Valid declare | 0 (winner) |
| Vinay | One pure sequence, no second sequence | Invalid declaration | 80 |
| Reema | First-life drop (no viable pure sequence) | First-life drop | 20 |
| Jay | Picked 3 from closed pile without top discard | Full count | 80 |

What trips up the show
| Pattern | Why it fails | Score |
|---|---|---|
| No pure sequence at the show | A pure sequence is required, jokers cannot bridge it. | 80 |
| Only one pure sequence, no second sequence or set | The hand needs a second pure sequence or a set. | 80 |
| Joker used in place of a pure-sequence card | Jokers do not count toward a pure sequence. | 80 |
| Wrong card printed-joker substitution | Printed joker substitutes for the card printed on it, not any missing card. | 80 |
| Set with two jokers of the same rank | Most platforms cap joker substitution at one per group. | 80 |
| 13 cards but miscounted total | The 14th card was discarded without grouping the rest. | 80 |
How-to-play questions readers send in
How many jokers are in a thirteen-card deck?
One printed joker plus one wild joker drawn from the closed deck. The card whose rank matches the printed joker becomes the wild joker for the round.
Can a joker stand in for a pure-sequence card?
No. A joker cannot substitute for any card in a pure sequence. It can stand in for one missing card in an impure sequence or in a set.
What is the cheapest way out of a bad hand?
A first-life drop costs 20 points. If you have not picked any card, drop immediately. The desk recommends making this decision before considering a middle drop.
What happens if I pick from the closed pile by mistake?
You keep the card; the draw stands. Picking from the closed pile is a legal draw. The full-count trigger happens when you reach for a third card from the closed pile without first picking the top discard.
Can I declare on my first turn?
Only if you were dealt a hand that already contains one pure sequence plus a second pure sequence or a set. The deck has thirteen cards, so this is rare but legal.
What if both players declare on the same draw?
The platform's rule page decides. Most platforms award the round to the player whose 14th card was discarded first; the desk recommends checking the platform's tie-break wording.
