An excellent billiards game can accurately calculate the hitting position, strength, the ball's traveling and rebounding route according to the mechanics principle, so as to play a magical ball with ease. Therefore, people call billiards "the performance of mechanical magicians".

There are three kinds of billiards: snooker, colored billiards and four-ball billiards, among which snooker is the basis of all kinds of billiards. Billiards competition is not only a fitness exercise, but also a more interesting competition activity. A game sometimes lasts a long time. In the competition, we should not only let ourselves score more points, but also try our best to set obstacles for the other side, so that the other side can make mistakes and lose points, thus defeating the opponent. Billiards players need to have good physical strength and a clear mind, because the use of tactics in billiards is closely related to mechanical principles.
