+A game consists of 10 frames. A frame is composed of one or two balls thrown, with 10 pins standing at the start of the frame. There are three cases for the tabulation of a frame:
 
-* An open frame is where a score of less than 10 is recorded for the frame. In this case the score for the frame is the number of pins knocked down.
+* An open frame is where a score of less than 10 is recorded for the frame. In this case the score for the frame is the number of pins knocked down after the second throw.
 
-* A spare is where all ten pins are knocked down after the second throw. The total value of a spare is 10 plus the number of pins knocked down in their next throw.
+* A spare is where all ten pins are knocked down after the second throw. The total value of a spare is 10 plus the number of pins knocked down in the next throw.
 
-* A strike is where all ten pins are knocked down after the first throw. The total value of a strike is 10 plus the number of pins knocked down in their next two throws. If a strike is immediately followed by a second strike, then we can not total the value of first strike until they throw the ball one more time.
+* A strike is where all ten pins are knocked down after the first throw. The total value of a strike is 10 plus the number of pins knocked down in the next two throws. If a strike is immediately followed by another strike, then the first strike's value cannot be totalled until the next throw.

 This means the current running total is 48.
 
-The tenth frame in the game is a special case. If someone throws a strike or a spare then they get a fill ball. Fill balls exist to calculate the total of the 10th frame. Scoring a strike or spare on the fill ball does not give the player more fill balls. The total value of the 10th frame is the total number of pins knocked down.
+The tenth frame in the game is a special case. If the player throws a strike or a spare, then they get one extra throw called a fill ball. Fill balls exist to calculate the total of the 10th frame. Scoring a strike or spare on the fill ball does not give the player more fill balls. The total value of the 10th frame is the total number of pins knocked down.
 
 For a tenth frame of X1/ (strike and a spare), the total value is 20.
 
 For a tenth frame of XXX (three strikes), the total value is 30.
