The inner edge of the snooker table is 350 cm long, 175 cm wide and 85 cm high. There are 22 balls for snooker, including red ball 15, colored ball 6 and white ball 1 (main ball). Arranged as shown on the right, numbers represent colored balls and their scores. The score of the red balls is 1, arranged in a triangle and placed between 6 and 7. The colors and scores of colored balls are as follows: 2-point ball: yellow 3-point ball: green 4-point ball: coffee 5-point ball: blue 6-point ball: pink 7-point ball: the semi-circular area on the black table is the tee area, and the diameter of colored balls is 2-4-3. Before the kick-off, both sides can decide who will kick off first by tossing a coin. The kickoff party can put the white ball anywhere in the kickoff area. After each stroke, the white ball must be played from where it stops. Players must hit a red ball first, and then they can choose a favorable colored ball to play the game. After the ball is scored, it needs to be taken out and put back to its anchor point. Then play the red ball, and then play the colored ball after the red ball scores. So repeatedly. After all the red balls are put into the bag, the colored balls must be played in the order from low ball to high ball, followed by yellow ball, green ball, brown ball, blue ball, pink ball and black ball. At this time, there is no need to take out the colored balls until all the colored balls are in the bag and there are white balls left on the table, and the game is over. The process from kick-off to all the balls being hit into the bag is called a game. In the process of playing ball, if one side fails to collect all the shots, or hits an illegal ball, then the right to hit the ball is given to the other side. You can play one game, three games, five games and seven games to decide. The final of the world professional championship is to play 35 games. If the two sides are tied in the end, the traditional way to decide the outcome is to put the black ball in the black position and the white ball in the service court. The two sides decide who plays first by tossing a coin, and the one who scores the black ball first is the winner. The outcome of each game is determined by the number of points scored by both sides, and the winner is the one with the highest score. There are two ways to score: one is to score by scoring goals, and the other is to score by punishing the other side for their mistakes. Each red ball scored 1 point, a yellow ball scored 2 points, a green ball scored 3 points, a brown ball scored 4 points, a blue ball scored 5 points, a pink ball scored 6 points and a black ball scored 7 points. So both sides will try their best to get more black balls into their pockets. Snooker rules stipulate that failure to observe the following rules is a foul and will be punished. When playing the red ball, if the white ball doesn't hit any red ball-empty shot, it will be punished by 4 points; If you accidentally hit the colored ball, you will be deducted according to the score of the colored ball, but at least 4 points will be deducted. That is, if you play black ball, you will be punished by 7 points, and if you play yellow ball, you will be punished by 4 points; When playing colored balls, if you don't hit the colored ball you want to play, you will be deducted according to the score of the colored ball. If you accidentally hit a colored ball with a high score, you will be deducted according to the high score, with a minimum deduction of 4 points. Therefore, after entering the red ball and before playing the colored ball, if the colored ball to be played is not obvious, you must declare which ball you played, otherwise you will be automatically fined 7 points; If you accidentally hit the white ball into the bag, you will be fined at least 4 points, or you will be punished according to the highest score that the white ball meets before entering the bag. After the white ball is put into the bag, the next player can put the white ball in any position on the service court to hit the ball; Penalty points are not deducted from the penalty party's points, but added to the opponent's points. The following acts are also illegal: (1) Knocking the ball off the table; (2) When hitting the ball, both feet leave the ground at the same time; (3) The white ball jumps over the middle ball and hits the target ball; (4) The ball on the table is touched by any object other than the hitting end of the club or any part of the body; (5) When hitting the ball, the club hits the white ball continuously for more than two times; (6) The cue, the white ball and the target ball contact at the same time. When the distance between the white ball and the target ball is less than 2.5 cm, it is very difficult to not violate the rules, so when the white ball is close to the target ball, only the batter is allowed to hit the white ball far, but not the target ball. In this special case, as long as the white ball is hit out of the target ball, it is regarded as hitting the target ball. Excellent players often take advantage of this opportunity to play safe ball or snooker.

Free ball:

When one side makes a mistake and snooker appears on the table, but the other side can't hit the red ball directly, you can choose a colored ball to play as a red ball. This colored ball is called a "free ball". If this colored ball is put into the bag, it will be put into the bag as a red ball and get 1 point, and then the colored ball will play as usual. But if the red ball on the table has been played and the opponent can't play the colored ball directly, then the opponent can play any colored ball, which is a free ball. The score of the free ball in the bag is calculated according to the lowest score left on the table, and the other balls are played in the normal order after scoring.

Play again:

If one side plays the wrong ball and puts the other side at a disadvantage, the other side has the right to ask the wrong side to continue the game. This rule, like the free kick rule, is designed to prevent either side from making deliberate mistakes and profiting from them. However, before making a decision to let the wrong side play again, we must ensure that every ball on the table has no chance, and we must correctly consider the level factor of the wrong side's playing.

Save the ball unconsciously:

If the referee thinks that one side should hit the ball after playing the wrong ball, he can punish the unconscious for saving the ball. In this case, the opponent can have the following options: (1) restore the ball to its original state before the wrong ball, and ask the wrong side to play again; (2) Ask the wrongdoer to continue the game at the current position; (3) Call yourself at the current position; (4) If snooker appears on the table, play the free ball yourself. Placement of colored balls: When the colored ball falls into the bag and is put back on the table, if the original position of the colored ball is occupied by other balls, the colored ball will be placed in the vacant position of the colored ball with the highest score at that time. If all the colored ball points are occupied, then the colored ball should be placed on a straight line perpendicular to the bottom of its anchor point-it should be closest to its anchor point and cannot touch other balls.

Deadlock:

When the referee thinks that the table is deadlocked, the referee will announce to both sides that if the situation does not change obviously after several rounds, the game is invalid and must be restarted.
