Official Gin Rummy Rules - Complete Guide to Playing

Learn the complete, official rules of Gin Rummy. Everything you need to know about setup, gameplay, knocking, going gin, scoring, and more.

Overview

Gin Rummy is a two-player card game played with a standard 52-card deck. Created in 1909, it remains one of the most beloved card games worldwide thanks to its perfect balance of simplicity and strategic depth.

The objective is straightforward: arrange the cards in your hand into valid combinations called melds while minimizing the point value of your unmatched cards, known as deadwood. The first player to reach a target score (typically 100 points) across multiple rounds wins the game.

What You Need

  • Players: 2 (standard game)
  • Deck: One standard 52-card deck (no jokers)
  • Scoring materials: Pen and paper or a score-tracking app

Card Values

Understanding card values is essential for managing your deadwood:

Card Point Value
Ace 1 point
2 through 9 Face value (2–9 points)
10, Jack, Queen, King 10 points each

The Deal

  1. Determine the first dealer by having each player draw a card. The player with the lower card deals first. In subsequent rounds, the winner of the previous hand deals.
  2. Deal 10 cards to each player, one card at a time, alternating between players.
  3. Place the remaining cards face down in the center of the table to form the stock pile (also called the draw pile).
  4. Turn over the top card of the stock pile and place it face up next to the stock pile to create the discard pile.

Types of Melds

There are two types of valid melds in Gin Rummy:

Sets (Groups)

A set consists of three or four cards of the same rank but different suits.

  • Valid: 7♠ 7♥ 7♦
  • Valid: J♣ J♠ J♥ J♦
  • Invalid: 7♠ 7♥ 7♥ (duplicate suits)

Runs (Sequences)

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

  • Valid: 4♥ 5♥ 6♥
  • Valid: 9♠ 10♠ J♠ Q♠
  • Invalid: Q♠ K♠ A♠ (Ace cannot be used as high)
  • Invalid: 4♥ 5♠ 6♥ (mixed suits)

Important: A single card cannot belong to two different melds simultaneously. You must choose one meld to assign each card to.

Gameplay

Starting the Hand

The non-dealer goes first. They begin by deciding whether to pick up the face-up card (the initial upcard) from the discard pile. If the non-dealer declines it, the dealer has the option to take it. If both players pass on the upcard, the non-dealer draws from the stock pile, and play proceeds normally from that point.

Taking a Turn

Each turn consists of two actions:

  1. Draw: Take either the top card from the stock pile (face down) or the top card from the discard pile (face up).
  2. Discard: Place one card from your hand face up on the discard pile.

After discarding, your hand should once again contain 10 cards. Your turn is then over and your opponent plays.

Goal During Play

On each turn, work toward:

  • Forming melds (sets and runs) to reduce deadwood
  • Lowering your deadwood count by discarding high-value unmatched cards
  • Tracking which cards your opponent picks up and discards to anticipate their melds

Ending a Hand

A hand can end in three ways:

1. Knocking

When your deadwood totals 10 points or fewer, you may choose to knock. To knock:

  1. Draw a card as usual.
  2. Place your discard face down on the discard pile (to signal a knock).
  3. Lay your hand face up, separating your melds from your deadwood.

Your opponent then lays out their melds and has the opportunity to lay off — adding cards from their deadwood onto your melds. For example, if you display a set of three 8s, your opponent may lay off their fourth 8.

Scoring a knock:

  • The knocker scores the difference between the opponent’s deadwood and their own.
  • If the opponent’s deadwood is equal to or less than the knocker’s, the opponent earns an undercut bonus (typically 25 points) plus the deadwood difference.

2. Going Gin

If you manage to form melds with all 10 cards and have zero deadwood, you can declare Gin. Going Gin is the strongest possible outcome:

  • Your opponent cannot lay off any cards against your melds.
  • You score the full value of your opponent’s deadwood plus a 25-point Gin bonus.

3. Draw (Stalemate)

If the stock pile is reduced to just two cards and neither player has knocked, the hand is a draw. No points are awarded, and the same dealer deals the next hand.

Scoring Summary

Outcome Points Awarded
Knock Opponent’s deadwood minus your deadwood
Gin Opponent’s deadwood + 25-point bonus
Undercut Opponent gets: your deadwood minus their deadwood + 25-point bonus
Draw 0 points (re-deal)

Winning the Game

The game is typically played to 100 points. Once a player reaches or exceeds 100 points, the game ends and final bonuses are calculated:

  • Game Bonus: The winner receives a 100-point bonus for winning the game.
  • Box Bonus (Line Bonus): Each player receives 25 points for every hand they won during the game.
  • Shutout Bonus: If the loser never won a single hand, the winner receives a double game bonus (200 points instead of 100).

Key Rules to Remember

  1. Aces are always low — they can only form runs like A-2-3, never Q-K-A.
  2. A card can only belong to one meld — no double-counting.
  3. You must discard after drawing — your hand should always return to 10 cards.
  4. You don’t have to knock — even if your deadwood is 10 or below, you can choose to continue playing.
  5. The stock pile can run out — if two cards remain and no one has knocked, it’s a draw.
  6. Laying off is only allowed after a regular knock — not after Gin.
