Gin Rummy Rules

Gin Rummy is a two-player game built around a single number: the deadwood limit. Everything either player does — every draw, every discard, every decision to keep playing instead of ending the hand — is aimed at getting the value of their unmatched cards under that number before the opponent does, and the entire strategic depth of the game comes from reading what your opponent is collecting from the cards they choose to keep or discard.

The deal and the stockpile

Each player is dealt ten cards from a standard 52-card deck. The remaining cards form a face-down stock pile, with the top card turned over beside it to start the discard pile. The non-dealer has the first option to take that face-up starter card; if they decline, the dealer may take it instead, and if both decline, the non-dealer draws from the stock to begin normal play.

Melds, runs, sets and deadwood

A meld is either a run — three or more consecutive cards of the same suit — or a set — three or four cards of the same rank. Any card not part of a completed meld is "deadwood," and each deadwood card counts against you at its face value: number cards at their pip value, face cards at 10, and aces at 1. The entire game is played toward minimizing your own deadwood total while, ideally, tracking what your opponent seems to be collecting so you can deny them useful discards.

Drawing, discarding, and when you're allowed to knock

On your turn, you draw one card — either the top of the stock pile or the top of the discard pile — and then discard one card face-up onto the discard pile, keeping your hand at ten cards throughout normal play. Once your deadwood total (after arranging your best possible melds) is 10 or less, you may "knock" instead of discarding: you lay your melds face-up, discard your final card, and set aside your remaining deadwood for your opponent to see.

Going gin, and why it's worth more than knocking

If your deadwood reaches exactly zero — every card in your hand melded, nothing left over — you can declare "gin" instead of an ordinary knock. Going gin scores a flat 25-point bonus on top of your opponent's full deadwood total, and critically, it locks the hand: your opponent gets no chance to reduce their own deadwood in response the way they can against an ordinary knock. Gin is the strongest way to end a hand, which is why a player sitting on a very low but nonzero deadwood total often has to weigh knocking immediately against waiting one more turn for the draw that completes gin instead.

Laying off, and the undercut that punishes a bad knock

When a player knocks with nonzero deadwood, their opponent gets to respond before scoring: any deadwood card the opponent is holding that extends one of the knocker's already-laid melds (a fourth card of the same suit-run, or matching rank) can be "laid off" onto that meld, reducing the opponent's own deadwood count for scoring purposes. This is where a knock can backfire badly. If the opponent's deadwood, after laying off everything possible, ends up equal to or lower than the knocker's, that's an "undercut" — the opponent scores the difference between the two deadwood totals, plus a bonus (commonly 25, though tables vary), instead of the knocker scoring anything at all. A player who knocks right at the 10-card limit without a real margin over what their opponent might be holding is the single most common way to hand an opponent a large, unearned swing.

Scoring a hand and playing to 100

Whoever scores on a given hand — the knocker, the gin-going player, or the undercutting opponent — adds that hand's points to a running total. Most tables play to 100 points, with the first player to reach or exceed that total winning the game outright; a common additional bonus is a flat 25-point "line" bonus per hand won, on top of the deadwood-based score, and a larger game-winning bonus (100 is typical) for the player who first reaches the target. Because the target is cumulative across many short hands rather than decided by one big hand, a Gin Rummy game tends to swing back and forth as both players alternate between small knock-outs and the occasional large gin or undercut.

Hollywood scoring: three games on one scoresheet

A common variant, nicknamed "Hollywood" scoring after its popularity among Golden Age film-set card games, runs three separate scoring columns on a single scoresheet at once rather than playing hands one game at a time. A hand's points get entered into whichever columns are still "open" — a column stays open until it's been credited at least once, then closes once it hits its own 100-point target, so early hands often score into all three columns simultaneously while later hands might only affect the one or two columns still running. It rewards more consistent play across an entire session rather than letting one early blowout hand decide a game outright.

Basic strategy: reading the discards, not just your own hand

Because both players see every card that passes through the discard pile, Gin Rummy rewards tracking what your opponent has passed on almost as much as it rewards building your own melds. Discarding a card in the middle of the rank or suit range (a 6 or 7, say) is generally riskier than discarding a card near the end of a run (an ace or a king), because middle cards connect to more possible melds an opponent might be building. Early in a hand, players commonly hold onto pairs and near-runs even if they're not yet a full meld, since a single well-timed draw can complete them cheaply; late in a hand, the calculation shifts toward safety, since every turn you don't knock is a turn your opponent might knock or go gin first. Watching which suits and ranks your opponent has picked up from the discard pile, rather than drawn blind from the stock, is the single clearest tell in the game — a player who suddenly takes a discarded 8 of hearts is very likely building something around 8s or the heart run near it.

Origins: a 1909 whist-club joke that outlived the joke

Gin Rummy is usually credited to Elwood T. Baker, a whist teacher working at a New York country club around 1909, who is said to have developed it (with his son, Charles Graham Baker) as a faster variant of an earlier game called Conquian. The name itself is widely told as a pun — gin being "one better" than rum, playing on rummy's name — though, like a lot of card-game etymology from that period, the exact naming story is passed down anecdotally rather than documented at the time. What's much better recorded is the game's second life: Gin Rummy became enormously popular among Hollywood actors and crew on film sets in the 1930s and 40s, where its short hand length made it ideal for filling gaps between takes, and that association is where "Hollywood scoring" gets its name.

The arguments this game actually produces

Laying cards off onto your own melds after knocking, extending a meld you already declared to reduce deadwood further before the opponent responds, is a move new players keep reaching for — it isn't legal: a knocker's hand is fixed the moment they lay down, and only the opponent gets to lay off. The second common dispute is whether the very first face-up starter card can be picked up by either player before any turn officially begins, or only in the specific non-dealer-then-dealer order described above — it's the latter; once both have passed on it, the starter card is treated as an ordinary discard pile card and no special first-pick right remains. More disputed calls are covered on the full dispute breakdown page. Hand totals, including full Hollywood-column worked examples, live on the scoring deep-dive page. The printable scoresheet already has the three-column layout set up.

Questions that come up mid-hand

Can you knock on the very first turn if your dealt hand is already under the deadwood limit? Yes, in principle — a hand dealt with 10 or less deadwood already arranged is knockable immediately, though this is genuinely rare given how ten random cards typically fall, and some casual tables restrict knocking until the second turn purely by house convention rather than an official rule.

Does the deck's joker get used in standard Gin Rummy? No — standard Gin Rummy is played with the 52 standard cards only, no jokers and no wild cards; the joker's absence is one of the clean differences between this game and rummy-family games like Canasta or Hand and Foot that build wild cards into the core mechanic.

If neither player can knock and the stock pile runs out, what happens? The hand ends in a push with no score for either player once only two cards remain in the stock (by convention, the stock is never drawn down to nothing, since the last two cards stay reserved) — both hands are set aside, and the next hand is dealt fresh with the deal passing normally.

Is there a maximum deadwood limit lower than 10 that some tables use? Yes — some casual groups agree to a stricter knock threshold before the first hand, commonly 7 or even 5, which makes gin relatively more valuable since ordinary knocks become available earlier and more often. Either threshold is legitimate as long as both players agree on it before dealing.
