Gin Rummy Melds - Sets and Runs Explained with Examples

A meld is any valid combination of cards that counts toward eliminating your deadwood. In Gin Rummy there are exactly two types: sets and runs. Understanding what makes each valid — and what makes them invalid — is the first step to improving your hand management.

Sets (Groups / Books)

A set is three or four cards of the same rank across different suits.

Valid Sets

Invalid Sets

Sets: Key Rules

• Exactly one card per suit. You can’t have two spade 7s in one set.
• Minimum three cards. Two cards of the same rank are a “pair” — useful as a building block, but not yet a meld.
• Maximum four cards. There are only four suits, so a set tops out at four cards.

Runs (Sequences)

A run is three or more consecutive cards of the same suit.

Valid Runs

Invalid Runs

Runs: Key Rules

• All same suit. Every card must share the same suit.
• Strictly consecutive. No gaps — 5-6-8 is not a run.
• Ace is always low. A-2-3 is valid; Q-K-A is not.
• No maximum length. A run can extend to all 13 cards of a suit in theory.

Deadwood: What’s Left After Melds

Once you’ve identified all your melds, every remaining card is deadwood. Deadwood is scored against you — the goal is to minimize it.

Deadwood Point Values

Example hand:

You hold: J♠ J♥ J♦ | 6♣ 7♣ 8♣ | K♦ 9♥ 3♠ 2♦

• Meld 1: J♠ J♥ J♦ (set of Jacks)
• Meld 2: 6♣ 7♣ 8♣ (run)
• Deadwood: K♦ (10) + 9♥ (9) + 3♠ (3) + 2♦ (2) = 24 points

With 24 deadwood you can’t knock yet (need ≤ 10). Your next priority: discard K♦ and 9♥ to bring deadwood below 10.

Building Toward Melds: Partial Combinations

You rarely start with complete melds. More often you hold partial combinations — cards that are one draw away from a meld. Knowing how to evaluate these is crucial.

Two-Card Builds

Connected two-card runs (like 6-7) can be completed by cards on either end — they’re more flexible than inside combinations (like 6-8, which need exactly the 7).

Three-Card Builds (One Away from a Meld)

The most valuable partial combinations are those that can be completed in multiple ways.

Can a Card Belong to Two Melds?

No. Once you lay down your hand, each card is assigned to exactly one meld or to deadwood. You cannot count a card in two melds simultaneously.

Example: You hold 7♠ 7♥ 7♦ and 5♠ 6♠ 7♠.

• The 7♠ can be in the set (7♠ 7♥ 7♦) or the run (5♠ 6♠ 7♠) — not both.
• When you knock, you must choose one assignment for each card. Assign 7♠ to whichever meld gives you the lowest remaining deadwood.

This situation — where one card could belong to multiple melds — is called a crossover card. Good players keep crossover cards in hand because they represent maximum flexibility.

Lay-Offs: Adding to the Opponent’s Melds

After a regular knock (not Gin), the non-knocking player may lay off their deadwood cards onto the knocker’s melds to reduce their own deadwood penalty.

How lay-offs work:

• If the knocker has the meld 7♠ 7♥ 7♦, the non-knocker may add the 7♣ to that set.
• If the knocker has the run 5♣ 6♣ 7♣, the non-knocker may add 4♣ or 8♣.

Lay-offs are not allowed after Gin. When a player goes Gin, their melds are sealed and the opponent must count their full unmelded hand as deadwood.
