How many points is gin in Gin Rummy?

On Classic Deck Games, gin scores a 25-point bonus plus the opponent’s full deadwood count. Layoffs are not allowed after gin.

How many points is an undercut?

An undercut scores a 25-point bonus plus the difference in deadwood after the defender lays off. Equal deadwood still awards the undercut bonus to the defender.

Layoffs do not score points by themselves. They only change the defender’s remaining deadwood before the knock comparison is made.

What if scores are tied at 100?

The match ends when a player reaches 100 or more after a hand. The higher total at that moment wins; both players can be over 100 only if the scoring hand awards enough points.

Gin Rummy Scoring Explained — Deadwood, Gin & Undercut

Gin Rummy scoring is simple once you know the three ways a hand ends after a knock or gin — and what happens when the stock runs down to two cards. This guide matches Classic Deck Games: first to 100 wins, gin +25, undercut +25, and classic cancelled stock-end hands.

Deadwood points

Deadwood is every card that is not in a legal meld. Face cards (J, Q, K) count 10 each, aces count 1, and other cards count their pip value. Lower deadwood makes knocks safer and gin bonuses larger for the winner.

Before you knock, discard one card face down. Only the deadwood that remains after that discard is scored.

Ace = 1
2–10 = face value
Jack, Queen, King = 10 each

Scoring a knock win

When you knock and keep lower deadwood than the defender after layoffs, you score the difference. If you knock with 4 and the defender has 19 after laying off, you score 15 points.

Layoffs matter. The defender may attach unmatched cards onto your exposed melds before totals are compared, which can cut their deadwood — or create an undercut.

Undercut scoring

If the defender’s deadwood is equal to or lower than yours after layoffs, they undercut you. They score a 25-point undercut bonus plus the deadwood difference.

Example: you knock with 8; after layoffs they have 5. They score 25 + (8 − 5) = 28. High knocks are expensive when the opponent can unload onto your melds.

Gin scoring

Going gin means zero deadwood after your face-down discard. You score a 25-point gin bonus plus the opponent’s full deadwood. The defender cannot lay off after gin.

Gin is powerful near the end of a match because the bonus alone can close a 20–30 point gap, but waiting for gin while you already have a safe knock can cost you the hand.

When the stock is down to two

If neither player knocks or goes gin and the stock is reduced to two cards, the hand is cancelled. No points are scored for either player.

Classic and most online sites use this rule. The same dealer shuffles and deals the next hand.

Match score to 100

Hand scores add to a running match total. The first player to reach 100 points wins the match. Late in a match, a small knock can be better than fishing for gin if it ends the game immediately.

Practice scoring on the table

Classic Deck Games shows hand outcomes after each knock or gin, including layoffs and bonuses, so you can connect the reveal animation to the scoreboard. Play a few matches and watch how undercuts punish high knocks.
