Gin Rummy
Gin Rummy is a game about knowing when to stop. Your hand is always nearly good enough, and the whole art is judging the moment when finishing beats improving.
Draw from the stock or the discard pile, then discard. Knock when your deadwood is ten or fewer.

How to play Gin Rummy
Two players, ten cards each. The rest of the deck sits face down as the stock, with one card turned face up beside it to start the discard pile.
Melds and deadwood
You are trying to arrange your hand into melds. A set is three or four cards of the same rank. A run is three or more consecutive cards in one suit — aces are always low, and runs never wrap, so Q-K-A-2 is not a run. Any card not in a meld is deadwood, and deadwood is what you are scored on: face cards count 10, aces count 1, everything else its face value.
A card can only belong to one meld. If you hold 7-8-8-8-9 of assorted suits you must decide whether the eight is part of the run or part of the set; it cannot be both.
The turn
Draw one card — either the top of the stock or the top of the discard pile — then discard one. If you took the discard, you may not throw that same card back this turn. That is the entire turn structure; the game is what you choose.
On the very first turn there is a small extra rule: the starting player may either take the face-up card or pass. If they pass, the opponent gets the same choice, and if they also pass, play begins normally from the stock.
Knocking
You end the round by knocking — discarding face down — and you may only do it when your deadwood totals ten or fewer, not counting the card you knocked with. Both hands are then revealed. The opponent may lay off any of their deadwood onto your melds: if you knocked with a run of A-2-3 of hearts and they hold the four of hearts, it attaches to your meld and stops being deadwood. The knocker can never lay off.
Gin is knocking with zero deadwood — all ten cards melded — and it earns a 25-point bonus. Big gin is having all eleven cards melded after your draw, worth 31, and it ends the round without a discard. Against gin, the opponent may not lay off at all.
Scoring
The knocker scores the difference between the two deadwood totals. If they have 3 and you have 21, they score 18. Add 25 for gin or 31 for big gin. But if the opponent's deadwood is equal or lower, they have undercut you: they score 25 plus the difference and you score nothing. Gin cannot be undercut. Reaching 100 ends the game, with a 100-point game bonus and 25 per hand won added to the totals.
Strategy
Gin Rummy gives you one decision per turn and about twenty turns per hand, and the good players are simply making that decision better.
Shed high cards early, keep low ones
Deadwood is scored by value, so a king you never meld costs ten and a two costs one. In the opening turns, throw face cards that are not obviously part of something. A hand of low cards that never comes together still loses cheaply; a hand of face cards that never comes together loses a round.
Keep cards that work two ways
The seven of hearts alongside the seven of clubs and the six of hearts is doing double duty — it could complete a set of sevens or a run in hearts. Cards with two futures are worth holding well past the point where a single-purpose card would be discarded, because each draw has twice the chance of helping.
Read the discard pile and stop feeding it
Every card your opponent takes from the discard pile tells you something concrete about their hand, and every card they ignore tells you something too. If they picked up a nine of spades, do not throw the eight or ten of spades. Beginners discard purely by what is least useful to them and hand their opponent exactly the card they were waiting for.
Knock early when you are ahead, hold for gin when you are safe
A knock with 8 points of deadwood against an opponent who has drawn heavily is usually worth taking — it may only score you ten or twelve points, but it denies them the round. Push for gin when you can see your hand is nearly there and the stock is still deep. Pushing for gin late in the stock is how you get undercut.
Respect the undercut
The undercut is the mechanic that punishes greed, and new players consistently forget it exists. Knocking with 10 points is legal but dangerous: any opponent sitting on 10 or less takes 25 points plus the difference off you. If your deadwood is at the top of the legal range, ask whether one more turn could get it lower before you commit.
Variants
- Oklahoma Gin — the value of the first turned card sets the maximum deadwood you may knock with. If it is a four, you need four or fewer; an ace means you must go gin.
- Hollywood Gin — three games scored simultaneously on a single scoresheet, which changes how much each individual hand matters.
- Straight Gin — no knocking at all: you must go gin to end the round.
- Round-the-corner Gin — aces may be high or low and runs wrap through king-ace-two.
- Play to 500 — a longer match target, common in club play, which rewards consistency over a single lucky hand.
Where Gin Rummy came from
Gin Rummy is a documented American invention: it was devised in 1909 by Elwood T. Baker, a whist teacher in Brooklyn, reportedly with his son C. Graham Baker, as a faster two-player alternative to the older game of Whiskey Poker. The naming follows that joke — gin instead of whiskey.
It stayed a minor game for two decades and then became a genuine craze in 1930s Hollywood, where it was the card game of choice on film sets because a hand could be finished between takes. That association carried it into mainstream American life, and by the 1940s it rivalled Contract Bridge for popularity. David Parlett records the Baker attribution in his history of card games, and John McLeod's archive documents the many scoring variations that grew up around the basic game. Its lasting appeal is structural: it is one of very few genuinely excellent card games that works with exactly two players and no partnership.
Questions people ask about Gin Rummy
- What is deadwood in Gin Rummy?
- Any card in your hand that is not part of a set or run. Face cards count 10 points, aces count 1, and the rest count their face value. Deadwood is what you are scored on, so keeping it low matters more than the number of melds you have.
- When am I allowed to knock?
- When your deadwood totals ten points or fewer, not counting the card you knock with. You end the round by discarding that card face down.
- What is an undercut?
- If you knock but your opponent’s deadwood is equal to or lower than yours, they undercut you: they score 25 points plus the difference and you score nothing. It is why knocking on exactly ten points is risky.
- What is the difference between gin and big gin?
- Gin is knocking with all ten cards melded and no deadwood, worth a 25-point bonus. Big gin is having all eleven cards melded immediately after drawing, worth 31, and it ends the round without you discarding at all.
- Can my opponent add cards to my melds?
- Yes — that is laying off. After you knock, they may attach their deadwood to your melds to reduce their own count. The exception is when you go gin, in which case no laying off is permitted.
- What happens if the stock runs out?
- If only two cards remain in the stock and nobody has knocked, the hand is a tie and neither player scores. It is a genuine outcome rather than a rare edge case, and it is worth playing towards when you are clearly behind in the hand.
