Scoring in Gin Rummy

In the United States, the most usual scoring system used in gin rummy is the 20/25 system, though the 10/20 system is more conservative.

10/20 system

If the knocking player goes gin, he gets 20 points, including the deadwood score of the player defending.

On the other hand, if the knocker does not gin, and the defending player has a lesser or similar deadwood count, the knocker is undercut, and gets ten points including the difference of his lower deadwood count.

If the knocker does not gin and is not undercut, he gets a point based on the margin of his lesser deadwood score compared to the defending player.

20/25 system

This is similar to the 10/20 system only the extra point for a gin is 25 points rather than 20, for the undercut bonus, the value is 20 instead of 10.

Single match

In a single match, the round of play proceeds until a player obtains more than one hundred points. That player is the winner of the game.

Multi-match

Monitoring both the match and game scores are very common in multi-match games. Match scores are brought back to zero at the beginning of every match, but the game scores pile up from every match, and determines the winner. The game comes to an end when a player has reached 100 match points.

At the conclusion of the match, players' match scores are added to their game scores as well. � 25 game points are awarded for every round won, � 100 points is awarded to the match winner � 100 bonus points to the winner of the match if no round was won by the loser.

Hollywood Scoring System

It basically enables three games to be played simultaneously. The scoring sheet is split into three groups of two columns. The headings of the columns indicate the initials of the players. When the first hand is won by any player, the score is noted in the initial column. A win in the second hand will be duly noted in the first two columns, and the total for the third hand is reflected on the three columns. When the scores in a certain column tally to the set amount (commonly 125), a cross is placed on the column, and additional scores will be disregarded.

The three games could be played immediately using several piles of cards, or could be played one at a time. Other games may have more than three games, adopting the same rules.
