According to the official Gin Rummy rules, the game is designed to be played by two to four players. Unlike Kalooki, Rummy 500 and Traditional Rummy online, Gin Rummy is played with only one standard deck of cards without Jokers (52 cards). Aces can only be used for low runs (i.e. A-2-3) and not for high runs (i.e. Q-K-A).

The four suits:

The cards and their values:

1 points2 points3 points4 points5 points6 points
7 points8 points9 points10 points10 points10 points
10 points     

In a 2 player game every player is dealt ten cards. In a three to four player game each player is dealt seven cards. The remaining cards form the deck are placed face down, and one open card is used as the first card of the discard pile.

The object of the game is to form as many melds from the cards in hand. A meld can be either a set or a run.

A set consists of 3 or more cards of the same rank:


A run consists of 3 or more consecutive cards of the same suit:


Apart from forming melds, players must try to reduce their deadwood count, or in other words to minimize the values of the cards that do not belong to any meld.

The Play
A turn in Gin Rummy is divided into two parts that make up a standard turn, except for the last turn of a hand/game.

  1. Drawing from the deck or the top card of the discard pile.
  2. Throwing a card to the discard pile.

The game can end in one of three ways:

  1. Gin – players lay down all the cards in their hand in valid melds, and throws the last card into the knock area. When a player Gins other players cannot add cards to that player’s melds.
  2. Knock – a player lays down valid melds and has a deadwood count that’s equal or lower than ten. In this move as well the player throws a card to the knock area.
  3. Undercut – when a player knocks his or her opponents can lay down their melds and also add cards to the knocker’s melds (but only to that player’s original melds).

For example: a player knocked and laid down.

The knocker goes down with:

The person playing next added 6H, meaning that the player who plays third will not be able to add 5H.

Through adding cards players can reduce their deadwood count, and therefore are rewarded for keeping the cards that the Knocker needed for his own melds.

The player who’s next in line can lay down two melds and has JH and 6H

And two 4s. In this case the opponent can add his cards to the appropriate meld, thus lowering the number of penalty points from 24 to 4!

Undercut – if one of the player knocks, and an opponent has a lower deadwood count, that opponent will win while the Knocker will be penalized by the sum of deadwoods minus undercutter’s deadwoods and additional 25 penalty points. If a player undercuts the knocker with the same deadwood count, the knocker is penalized 25 points.

If only 2 last cards are left in the deck, the discard pile is reshuffled and used as the new deck.

Defeated (Penalty Points):

Ginning Sum of deadwoods + 25 penalty points.
Knocking Sum of deadwoods minus knockers deadwoods.
Undercut Sum of deadwoods minus undercutter’s deadwoods. Knocker receives 25 extra penalty points.

Prize distribution in Gin Rummy games

According to our Gin Rummy rules the winner receives 75% of the pool prize (minimum), and the rest is divided between the other players. Players’ win percentage is calculated according to their penalty points and the winner’s, as long as they have less than 50 penalty points than the winner.
