What Is Gin Rummy?
Gin Rummy is a classic two-player card game in which each player organizes ten cards into melds and tries to reduce the value of unmatched cards, called deadwood. It rewards memory, timing, probability, and careful discards. At Gin Rummy Hall you can play Gin Rummy online free against a computer opponent without downloading an app or creating an account.
Players, Deck, and Deal
- Players: two.
- Deck: one standard 52-card deck without jokers.
- Cards dealt: ten cards to each player.
- Stock: the remaining cards are placed face down.
- Discard pile: one card is placed face up next to the stock.
The non-dealer normally receives the first opportunity to take the face-up card. If that player passes, the dealer may take it. If both pass, the non-dealer draws from the stock and normal play begins.
Sets, Runs, and Melds
A meld is a legal group of at least three cards. There are two types:
Sets
Three or four cards of the same rank, such as three queens.
Runs
Three or more consecutive cards in the same suit, such as 4♠–5♠–6♠. In the standard rules used by Gin Rummy Hall, an ace is low: A–2–3 is valid, but Q–K–A is not.
A card cannot belong to two melds at the same time. When several layouts are possible, the best layout is the one that leaves the fewest deadwood points.
How a Turn Works
- Draw one card from either the face-down stock or the top of the discard pile.
- Review your eleven-card hand and decide which cards help your sets and runs.
- Discard one card face up, returning your hand to ten cards.
You may not pick up the top discard and immediately throw that same card back during the same turn. In the online game, unavailable actions are disabled automatically.
What Is Deadwood?
Deadwood means cards that are not part of any set or run. Aces count 1 point, number cards count their face value, and jacks, queens, and kings count 10 points each. High unmatched cards are expensive, which is why players often release isolated face cards early.
When Can You Knock?
After drawing and choosing a discard, you may knock when the remaining ten-card hand has 10 deadwood points or fewer. Knocking ends the round and both hands are compared. The opponent may be allowed to lay unmatched cards onto the knocker’s melds before final deadwood is counted.
What Does Going Gin Mean?
You go gin when all ten cards form melds and your deadwood is zero. Going gin earns the opponent’s deadwood value plus a 25-point bonus in Gin Rummy Hall. The opponent cannot lay off cards when you go gin.
Laying Off Cards
After a normal knock, the defending player may add deadwood cards to the knocker’s melds. For example, a 7♣ can be added to a 4♣–5♣–6♣ run, and a fourth 9 can be added to a three-card set of nines. Layoffs reduce the defender’s final deadwood. They do not apply after gin.
What Is an Undercut?
An undercut occurs when the defender’s final deadwood is equal to or lower than the knocker’s deadwood after legal layoffs. The defender wins the round and receives the deadwood difference plus a 25-point undercut bonus.
How the Match Ends
Rounds continue until a player reaches the target score. Gin Rummy Hall uses a target of 100 points. A round can also end without a score when the stock is exhausted under the game’s rules.
A Simple Example Round
You hold a melded run and set, with 8♣ and A♦ left as deadwood. Your deadwood total is 9, so you may discard another card and knock. If your opponent has 18 deadwood points after layoffs, you score 18 − 9 = 9 points. If the opponent can reduce to 9 or less, the opponent undercuts you.
Common Beginner Mistakes
- Holding several unrelated kings, queens, and jacks for too long.
- Taking every discard that looks useful and revealing too much information.
- Discarding a card close in rank to cards the opponent has collected.
- Forgetting that a flexible card may connect to more than one possible run.
- Waiting for gin when a safe knock would likely win the round.
