For this article the two players are identified as Player A, who is the scorekeeper and Player B who is considered the opponent. On the score sheet the first three columns are headed by the letter A and the last three columns are headed by the letter B.

This is an example of how a game of Gin Rummy might go, and how you use the score sheet to keep score:

1st hand – Player A knocks with 8 points, Player B has 20 points in unmatched cards. Therefore, Player A scores 12 points in the first column.

2nd hand – Player A goes gin and Player B has 14 points. In the second column headed A, insert the number 2 with a circle completely around it, as well write down the number 2 with a circle around it in the first column. This represents the bonus boxes a player receives for going gin. These boxes are worth 25 points each in the final scoring. In the box directly under the encircled 2 in the second column insert the number 39 which represents the 25 points for gin plus the 14 points in the loser’s hand. In the first column headed A, add 39 to the original 12 that was in the column, and insert the total of 51 directly under the encircled 2 in that column.

3rd hand – Player A knocks with 8 points, but after Player B lays off one of his unmatched cards on Player A’s hand, Player B is only left with 7 points, which means he has underknocked Player A by 1 point. Since an underknock wins one bonus box, place a 1 in a circle in the first box of the first B column. Directly under this circled 1, you insert 26. This score represents the 25 point bonus for underknocking plus the one point difference in the hand.

4th hand – The next knock card that shows is the Ace of spades which means the score is doubled. Player A gins the hand and Player B has 30 points. You insert the number 4 with a circle around it in the first box of the third A column, and in the second and first A columns directly under the previous scores. Under the encircled 4 in the third column, insert the score 110. This represents the 25 points for gin plus the 30 points in the opponent’s hand. The 55 is doubled because of the spade. The 110 points are also added to the previous scores in the second and first A columns for 149 and 161 totals respectively.

You continue on until either Player A or B has surpassed 250 points in the first column. After this happens you place a vertical line in the column of the player that lost to indicate that this game is over and there will be no further scoring in the columns. You do this with each column until scores are only put into the third column.
