Hit it all: When the first pitch of each grid knocks down all ten vertical bottles, it is called hit it all. Use the (X) symbol to record it in the small box on the left above the box on the scoreboard. The score of the whole middle school is 10 plus the number of bottles knocked down by the athletes in the next two pitches. The highest score of a game is 300 points, and athletes must throw twelve all-hits.

Make-up: When the second pitch knocks down all the remaining bottles of the first ball in the grid, it is called make-up, which is indicated by (/). Record it in the small box in the upper right corner of the box. The score of the make-up exam is 10 plus the number of bottles knocked down by the athlete in the next ball.

Mistakes: Except for the cracked bottles formed after the first pitch, when an athlete fails to knock down all ten bottles after two pitches in a certain box, it is a mistake.
