What Is Gin Rummy?
Gin Rummy is a two-player card game and one of the most popular versions of Rummy ever created. Each player holds 10 cards and tries to organize them into valid melds — matched groups and sequences — while reducing their leftover unmatched cards to as few points as possible. When you feel your hand is good enough, you end the round by ‘knocking.’ Or, if you’ve organized every single card into melds with nothing left over, you call ‘Gin!’ for a big bonus. The player with the best hand at each round scores the difference.
What You Need
- One standard deck of 52 playing cards
- Exactly two players
- Paper and pen for scoring
Two Key Terms to Understand
Meld: A valid group of cards that fit together. There are two types: a Set (three or four cards of the same rank, any suits — like three Kings or four 7s) and a Run (three or more consecutive cards all in the same suit — like the 4, 5, 6, and 7 of Clubs).
Deadwood: Any cards in your hand that do NOT belong to a meld. These are your leftover, unmatched cards. Your deadwood total is the sum of their point values: Aces = 1 point, face cards = 10 points, all others = face value. The lower your deadwood, the better.
Setting Up the Game
- Shuffle all 52 cards.
- Deal 10 cards to each player, one at a time, face-down.
- Place the remaining 32 cards face-down in the center as the stock pile.
- Flip the top card of the stock pile face-up and place it next to the stock. This starts the discard pile.
- The non-dealer gets the first opportunity: they may take the face-up discard card or pass. If they pass, the dealer may take it. If the dealer also passes, the non-dealer draws from the stock and the game begins normally.
How to Play — Step by Step
Play moves back and forth between the two players. On each turn:
- Draw: Take the top card from either the face-down stock pile or the face-up discard pile. Add it to your hand (you now have 11 cards temporarily).
- Organize your hand mentally: Look for melds. Try different combinations. Which cards fit together into sets or runs? Which cards are left over as deadwood?
- Knock or continue: You have a choice. Either end the round by knocking (explained below), or simply discard one card face-up onto the discard pile to end your turn, and the game continues.
How to Knock
You may knock when your deadwood — the unmatched cards in your hand after forming your best possible melds — totals 10 points or less. To knock:
- Discard your final card face-DOWN onto the discard pile (face-down signals a knock, face-up is a normal discard).
- Spread your hand face-up on the table. Clearly separate your melds from your deadwood so your opponent can see both.
- Your opponent now reveals their hand. They organize their best possible melds.
- Your opponent gets one extra privilege: they can lay off their unmatched deadwood cards onto YOUR melds. For example, if you have a set of three 7s, your opponent can add their 7 to your set — this reduces their deadwood total.
Calculating the Result After a Knock
After lay-offs, count both players’ deadwood:
- Knocker wins: If your deadwood is lower than your opponent’s, you score the DIFFERENCE. Example: your deadwood = 4 points, opponent’s deadwood after lay-offs = 11 points. You score 7 points.
- Undercut: If your opponent’s deadwood (after laying off) is equal to or LESS than yours, your opponent wins — and they score the difference PLUS a 25-point undercut bonus. This is a punishment for knocking too early when your opponent is actually in better shape.
- Gin: If you have ZERO deadwood — all 10 cards are in melds — you call ‘Gin!’ instead of knocking. You score your opponent’s full deadwood total PLUS a 25-point Gin bonus. Your opponent may NOT lay off any cards when you go Gin.
When the Stock Runs Low
If the stock pile runs down to two cards and no one has knocked, the hand is declared a draw. No points are scored. Shuffle and deal a new hand.
Scoring and Winning
Keep a running total of points scored. The first player to reach 100 points wins the game. That player also earns a 100-point game bonus. Each individual hand won earns an additional 25-point line bonus. If your opponent scored zero points across the entire game, you earn an extra 100-point shutout bonus.
Tips for New Players
- Draw from the discard pile only when the card directly fits into a meld you’re building — otherwise you’re showing your opponent exactly what you need.
- Don’t hold onto high-value deadwood (Kings, Queens, face cards) hoping they’ll become part of a meld — they cost 10 points each if you get caught holding them.
- Knock as soon as your deadwood drops to 5 or below — waiting for Gin gives your opponent more chances to catch up.
