How to play 3-13

3-13 — also called Three Thirteen — is an eleven-round rummy for two or more players. Each round deals one more card than the last, a different rank is wild every round, and the lowest total score wins. A full game takes about forty-five minutes and one argument about whether a run can use two of the same card. (It can’t. See below.)

What you need

The deal

Round one deals three cards to each player; every round after deals one more, up to thirteen cards in round eleven. The deal rotates left each round. After the deal, the next card goes face-up to start the discard pile and the rest becomes the stock.

Wild cards

The rank that matches the round’s deal is wild: 3s in the three-card round, 4s in the four-card round, and so on up to Kings in the last. A wild card stands in for any card in a set or a run. This is the rule everyone forgets mid-round — it’s why the app prints the wild rank at the top of every scoring screen.

Melds

You’re trying to arrange your whole hand into melds. Two kinds count:

Aces are low: A-2-3 is a run, Q-K-A is not. A card can belong to only one meld at a time.

Two decks, one card twice? A set may contain identical twins — ♣9 ♣9 ♦9 is legal. A run may not: the second copy of a card doesn’t extend a sequence, so 4♥ 5♥ 5♥ 6♥ is not a run. Split the twins across two melds instead.

Your turn

Draw one card — the top of the stock, or the top of the discard pile. Then discard one, face up. That’s the whole turn; the skill is in what you keep.

Going out

When you can form your entire hand into melds except one card, you may go out: lay down your melds and discard the last card. Every other player then gets exactly one more turn to tidy up before the round is scored. You can’t add cards to another player’s melds.

Scoring

Only unmatched cards score, and they score against you: aces are 1, twos through tens are face value, and Jacks, Queens, and Kings are 10 each. The player who went out usually marks a zero. Totals accumulate across all eleven rounds — lowest total after the Kings round wins. Full point tables live on the scoring sheet.
