Gin Rummy Rules for Beginners — Complete Guide

Gin Rummy is a two-player card game where players draw and discard cards to form sets (3-4 of a kind) and runs (3+ consecutive cards in a suit). Here is a complete guide to the rules, from setup to scoring, so you can start playing right away.

What Is Gin Rummy?

Gin Rummy is a two-player card game from the Rummy family. The objective is simple: form combinations of cards called melds while minimizing the point value of unmatched cards, known as deadwood. A standard 52-card deck is used with no jokers.

The game is played over multiple rounds. Each round ends when one player knocks or goes gin, and points are tallied. The first player to reach an agreed-upon target — typically 100 points — wins the match.

What You Need to Play

• Players: 2
• Deck: Standard 52-card deck (no jokers)
• Pen & paper or a scoring app to track points

Card Values

These values matter for two reasons: they determine your deadwood count when you knock, and they are used to calculate scores at the end of each hand.

How to Deal

1. Choose a dealer — many players cut the deck and the lower card deals first.
2. The dealer gives each player 10 cards, one at a time, alternating between players.
3. Place the remaining deck face-down in the center to form the stock pile.
4. Flip the top card of the stock face-up beside it to create the discard pile.
5. The non-dealer decides whether to take the face-up card or pass. If they pass, the dealer may take it or pass. If both pass, the non-dealer draws from the stock pile and normal play begins.

Understanding Melds

Melds are the card combinations you are trying to build. There are two types:

Sets (Groups)

Three or four cards of the same rank but different suits. For example: 7♠ 7♥ 7♦.

Runs (Sequences)

Three or more consecutive cards of the same suit. For example: 4♣ 5♣ 6♣. Aces are always low, so A-2-3 is valid but Q-K-A is not.

Any card in your hand that is not part of a meld is deadwood.

Turn Sequence: Draw and Discard

Each turn follows two steps:

1. Draw — Take either the top card of the discard pile or the top card of the stock pile.
2. Discard — Place one card from your hand face-up on the discard pile.

Your hand always ends with 10 cards after discarding. The goal each turn is to improve your melds and reduce deadwood.

How to Knock

When the total point value of your deadwood cards is 10 or less, you may choose to knock instead of discarding normally. To knock:

1. Place your final discard face-down on the discard pile.
2. Spread your hand on the table, separating melds from deadwood.
3. Your opponent then reveals their hand, lays off any cards that extend your melds (unless you went gin), and separates their own melds and deadwood.

The difference in deadwood points determines who scores. If you knocked and your deadwood is lower, you earn the difference. If your opponent’s deadwood is equal to or lower than yours, they score an undercut bonus (typically 25 points) plus the deadwood difference.

Going Gin

If you can meld all 10 cards with zero deadwood, you go gin. This is the best possible outcome for a hand:

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

Because of the large bonus, going gin is always worth pursuing — but waiting too long can let your opponent knock first.

Laying Off Cards

When the knocker’s hand is revealed, the non-knocking player can lay off individual deadwood cards onto the knocker’s melds. For example, if the knocker shows 5♠ 6♠ 7♠, the opponent may add their 4♠ or 8♠ to that run.

Laid-off cards no longer count as deadwood. This is one reason knocking with high deadwood can backfire — your opponent may lay off enough to undercut you.

Exception: Lay-offs are not permitted when the knocker goes gin.

Scoring Summary

At the end of the match (usually 100 points), additional bonuses may apply:

• Game bonus: 100 points for winning the match.
• Box bonus (line bonus): 25 points for each hand won.

See the Scoring Guide for a full breakdown.

Example Hand Walkthrough

Imagine you are dealt: A♠ 3♠ 4♠ 5♠ 7♥ 8♥ 9♣ J♦ Q♦ K♦.

• Melds so far: 3♠-4♠-5♠ (run) and J♦-Q♦-K♦ (run).
• Deadwood: A♠ (1), 7♥ (7), 8♥ (8), 9♣ (9) = 25 points — too high to knock.

Your priorities each turn:

1. Try to extend existing melds (draw the 2♠ or 6♠, or the 10♦).
2. Pair up deadwood cards (drawing another 7, 8, or 9 could start a new set).
3. Get rid of high-value deadwood first — discard the 9♣ or 8♥ early.

After several turns, suppose you’ve drawn 6♠ and another 7. Your hand becomes 3♠-4♠-5♠-6♠, J♦-Q♦-K♦, 7♥-7♣-7♦ with A♠ as your only deadwood (1 point). You knock and are almost certainly winning the hand.

Quick-Reference Rule Checklist

1. Deal 10 cards each; flip one card to start the discard pile.
2. Non-dealer acts first on the face-up card.
3. Each turn: draw one card, then discard one card.
4. Form melds (sets or runs) and reduce deadwood.
5. Knock when deadwood ≤ 10 points; go gin with zero deadwood.
6. Opponent lays off cards (unless gin), then compare deadwood.
7. Score the difference plus any applicable bonuses.
8. First to the target score wins.

Tips for Your First Few Games

• Discard high deadwood early. Kings, Queens, and Jacks cost you 10 points each if they stay unmatched.
• Watch what your opponent picks up. If they take a card from the discard pile, they almost certainly need it for a meld.
• Don’t hold three unrelated face cards hoping for sets — the odds are against you.
• Knock when you can. Waiting for gin when you could knock with 2 or 3 deadwood often backfires.
