Edit the rules of this paragraph

Snooker matches are played by two or more people individually or in separate sides. It can be summarized as follows: 1.

The points for a player's foul penalty shall be added to the opponent's score record; 5. The basic tactic in snooker is to try to keep the cue ball where your opponent has no live ball to play. That is to create obstacles for your opponent. If one player is many points behind the opponent, then creating obstacles to cause the opponent to be penalized becomes a very important means of scoring. 6. The winner of a set shall be a player or a party: 1. Get the highest score. 2. The opponent concedes the set, or the opponent is penalized due to "unintentional save" or "improper conduct". 7.

The black ball is placed on the ball setting point. 2. After the start of the game, only the referee may wipe the ball at the reasonable request of the batting team, and: a) If the ball is not on the spot, the position of the ball should be marked with a locator before it is picked up; b) The locator used to mark the position of the wiped ball will be treated as the ball and the score of the ball will be obtained until the ball is wiped and returned to its original position. If any player other than the batsman touches or disturbs the locator, he will be penalized as if he were the batsman and the order of play will not be affected. If necessary, the referee may return the locator or wiped ball to its original position, even if the ball has been picked up. 10． Competition method: Before the start of the competition, the participating parties should determine the order of the competition by drawing lots or by mutual agreement. 1.
