How to Play Gin Rummy

Knock before they do.

👥 2 players · Medium difficulty

Learn two-player Gin Rummy: melds, deadwood, knocking and undercuts. Count a ten-card example and practise deciding when to knock.

Count deadwood before you knock

3♣3♦3♥4♠5♠6♠7♠A♣2♦4♥

The three threes form a set; 4♠–7♠ form a run. Only A♣, 2♦ and 4♥ remain unmatched: 7 deadwood points. You may knock after discarding, but your opponent can still undercut you.

Worked example
Situation	Result
A♣ + 2♦ + 4♥	7
Opponent has 12 after laying off	You score 5
Opponent has 5 after laying off	Opponent scores 27

The undercut example includes Vanikar’s 25-point bonus. Gin requires zero deadwood and prevents your opponent from laying off.

Reach 100 points first by reducing deadwood to 10 or fewer to knock, or to 0 for Gin.

🃏 Gin Rummy Setup & Rules

Use a standard 52-card deck. Aces are low. Deal 10 cards each.
Flip one card face-up (discard pile start); rest is the stock.
The non-dealer takes the first turn like any other: draw from the stock or take the face-up card, then discard.

▶ How to Play Gin Rummy

On your turn, draw from stock or top of discard. Then discard one card.
A meld is a set (3–4 same rank) or run (3+ consecutive same suit).
Knock by discarding face-down when your unmatched cards total ≤ 10.
After a knock, both hands are revealed; the app lays off any of the opponent's cards that fit your melds and scores the hand at once.
Gin: knock with 0 deadwood — opponent cannot lay off.

📖 Detailed Guide

Setting up the game

Gin Rummy is heads-up: you against one opponent, racing to 100 points across multiple hands.
Each player gets 10 cards. One card is flipped face-up to start the discard pile; the rest sit face-down as the stock with a live counter ("Draw: 31").
The non-dealer takes the first turn like any other: draw from the stock or take the face-up card, then discard. You may not discard the card you just took from the discard pile.

Arranging your hand

Use the sort bar at the bottom to instantly arrange your hand: by suit (C D H S) or by rank (A→2), then confirm with the check mark.
Group toward melds: a SET is 3–4 cards of the same rank; a RUN is 3+ consecutive cards of the same suit (Aces are low).
Everything not in a meld is "deadwood," counted at face value (face cards 10, Ace 1). Your whole game is about shrinking that number.

Draw, then discard

Each turn has exactly two actions: draw one card (from the stock or the top of the discard pile), then discard one card face-up.
Taking from the discard pile telegraphs what you're collecting — sometimes drawing blind from stock is worth the privacy.
Watch what your opponent picks up and never feed the cards they want.

Knocking, Gin, and scoring

When your deadwood totals 10 or less you may knock: tap Knock to discard face-down and reveal your melds.
The app then lays off automatically any of your opponent's cards that fit YOUR melds, shrinking their deadwood, and the difference in deadwood goes to the knocker.
If the opponent's final deadwood is equal or lower, they "undercut" you: they score the difference plus a 25-point bonus.
GIN — tap Gin! when your deadwood is zero — earns a 25-point bonus and blocks all layoffs.
Hands repeat until someone reaches 100 points; the higher total then wins. The loser of a hand takes the first turn of the next one. If the stock runs out, the hand is a draw and nobody scores.

📊 Gin Rummy Scoring

Knocker wins the difference in deadwood. Undercut: the opponent wins the difference plus 25. Gin: 25 plus the opponent's full deadwood. First to 100 wins.

❓ Gin Rummy — Frequently Asked Questions

How many players do you need for Gin Rummy?

Gin Rummy is played with 2 players. On Vanikar, empty seats can be filled with AI opponents so you can always start a game.

When can you knock in Gin Rummy?

After drawing, when the cards in your hand that are not in a set or run add up to 10 or fewer. Discard, lay down your melds, and your opponent lays off what fits on them before deadwood is counted.

What is an undercut in Gin Rummy?

When the player who was knocked on finishes with equal or lower deadwood after laying off. They score the difference plus 25 instead of the knocker. Knocking with 9 or 10 deadwood against a careful opponent invites it.

Can you take the first upcard in Gin Rummy?

The non-dealer may take the first upcard or pass; if they pass the dealer may take it; if both pass, the non-dealer draws from the stock. Nobody may draw from the stock before the upcard has been offered.

What happens if the stock runs out in Gin Rummy?

When only two cards remain in the stock and the player to draw does not knock, the hand is void: no score, and the same dealer deals again.
