Gin Rummy Strategy and Tips

Here is how to think about winning at Gin Rummy, split into short lessons. Each one reads on its own, and each one comes with a real position: press Try it on the board and you play the move yourself.

Draw before discarding

Lesson 1

Your usual hand has ten cards. Drawing makes eleven, and you then choose one card to discard. The stock is hidden, but the top discard is visible, so you can check whether it helps a meld before taking it. Buried discards cannot be selected.

A card taken from the discard pile cannot be returned on the same turn. A card drawn from stock may be discarded immediately. Before taking a visible discard, think about which different card you will let go. There is no undo after drawing.

Try drawing from stock on the board. You must discard before the opponent’s turn begins. Knocking also starts by selecting a discard: count the ten cards that would remain, not all eleven cards currently in your hand. Ten or fewer deadwood points allows a knock.

Discard what the opponent cannot use

Lesson 2

Every discard lands face up in front of your opponent. When two spare cards cost the same, let go of the one they cannot use. You can work that out from the cards you can see: your own hand and the top of the discard pile.

This hand holds a set of queens and the four, five and six of hearts. The spare cards are the king of spades, the king of hearts, the jack of clubs, the three of diamonds and the five of clubs. Both the king of spades and the jack of clubs are worth ten. The only run containing that king is jack-queen-king of spades, and the queen sits in your own meld. A set of kings is impossible too: you hold one king and another lies face up on the pile.

The jack of clubs is the opposite. The other three jacks are unseen, and the runs nine-ten-jack and ten-jack-queen of clubs are both still open. When the cost is the same, throw the card that cannot help.

Read their melds from what they pick up

Lesson 3

A draw from the stock tells you nothing. A card taken from the discard pile tells you a great deal, because you saw it go across. The opponent is collecting around that card: either a set of the same rank or a run in the same suit.

Here the opponent takes the nine of diamonds, so you know it is in their hand. Your spare ten of diamonds fits both eight-nine-ten and nine-ten-jack of diamonds. Discarding it now could hand them a finished meld.

Throw the king of clubs you just drew instead. It costs ten points and belongs to nothing. What the opponent picked up stays useful for the rest of the deal, so keep track of every card they take from the pile.

Knock now, or wait for gin?

Lesson 4

You may knock once your deadwood falls to ten points or fewer. The difference between the two deadwood counts becomes your score. Zero deadwood is gin, which adds a 25-point bonus.

The spare cards here are the two and the four of diamonds: six points. Drawing the three of diamonds would make gin, but that single card is somewhere among the thirty left in the stock, and the opponent may knock first. Discard the four and your deadwood is the lone two, so you can knock at once.

As a guide, knock early once your count is small. A knock right on ten points is the risky one: if the defender’s deadwood is equal or lower they undercut you and take 25 points plus the difference. A two-point knock leaves almost no room for that.

Try it on the board

Pick a lesson and the board starts from that position. Start over as often as you like.
