What Are the Basic Rummy Terms?

Quick Reference
The essential Rummy vocabulary includes: Meld (valid combination), Set (same rank), Run (sequence), Deadwood (unmatched cards), Knock, Gin, Undercut, and Layoff.

Card Combination Terms

Meld

A valid combination of cards that scores 0 deadwood points. Melds are either sets or runs.

Set (Group, Book)

Three or four cards of the same rank in different suits.

Examples

7♠-7♥-7♦ (set of three) | K♠-K♥-K♦-K♣ (set of four)

Run (Sequence)

Three or more consecutive cards of the same suit.

Examples

4-5-6♥ (run of three) | 9-10-J-Q♠ (run of four)

Deadwood

Cards in your hand that aren't part of any meld. Deadwood points determine if you can knock and affect scoring.

Gameplay Terms

Stock Pile (Draw Pile)

The face-down deck from which players draw cards.

Discard Pile

The face-up pile where players discard unwanted cards. The top card is always available to draw.

Knock

Ending the round when your deadwood is 10 points or less. You reveal your hand and opponent can lay off.

Gin

A perfect knock with 0 deadwood (all cards in melds). Earns a 25-point bonus and prevents opponent layoffs.

Layoff

After your opponent knocks (but not Gins), you can add cards from your hand to their melds to reduce your deadwood.

Undercut

When the defending player (non-knocker) has equal or less deadwood after laying off. Earns a 25-point bonus.

Scoring Terms

Box (Line)

A bonus (typically 25 points) awarded for winning a hand. Sometimes called "box bonus" or "line bonus."

Game Bonus

Extra points (typically 100) awarded to the player who first reaches the target score (usually 100+ points).

Shutout (Schneider, Blitz)

When a player wins without their opponent winning any hands. Often doubles the game bonus.
