Bowling rules

Bowling is determined by the number of bottles knocked down. A game is divided into 10 rounds, and each round has two pitching opportunities. If all the 10 bottles are knocked down in the first pitch of a round, that is, all the bottles are hit, you can't pitch any more. Only 10 round is different. If you hit all the balls in the first pitch, you still have to finish the last two shots. If it is a make-up, we must continue to throw the last ball and end the overall situation. It is worth emphasizing that if the 10 bottle is not knocked down by two shots, the third chance will be cancelled automatically.

Bowling, also known as "ground ball", is an indoor sport of hitting wooden bottles with a ball on a wooden fairway, which is popular in some countries in Europe, Oceania and Asia. In bowling competition, the number of passes and the order of pitching are determined by drawing lots.

? method of marking

Bowling has a unified scoring format. There are 2 1 box in ten rounds of a game. The box on the left of each round is the score of the first pitch, and the box on the right is the score of the second pitch. If the first goal is "all-in", in addition to the original ten points, you can also add the scores of two goals in the next round and record the scores in the "all-in" box. For example, in the first round, the first ball hits a perfect score, and in the second round, the two balls hit 9 points, so you can write 19 points in the box of "all hits", which is the score of the first round. In bowling, hitting the target is the key to scoring.

"All hits": Ten bottles are knocked down in the first pitch of a round, and the score is recorded as ten, and the score of two balls in the next round can be added.

"Play-off": In a round, the first pitch did not knock down all the pins, but when the second pitch was thrown, all the pins were knocked down, and the score was recorded as ten, which can be added to the score of the first ball in the next round.

"Foul": In a round, when the first ball is thrown, if the foot steps on or crosses the foul line, the ball scores zero; If you step on or cross the foul line when throwing the second ball, you will only get the score of the first ball.
