If the serve touches any part of the service box (including the white lines that enclose it), then the serve is in. This includes barely nicking any part of the line.
A service break occurs when a player wins the game when their opponent is serving.

The person serving is the one who starts the point with a serve (hitting the ball out of their hand). The service change is when the other player starts the point (serves). Multiple service changes happen in a single game allowing each player opportunities to serve.

In tennis, when the player serving is losing by a score of 15-40, this is considered "double break point" as his opponent has two opportunities to win the game or "break" his service.
Foot Fault
A service ace in tennis is very important as it is a point won directly from the serve without the opponent being able to return the ball. It can give the serving player a significant advantage in the game by putting pressure on the opponent and potentially leading to a quick win in the set.
In tennis, the service line is a boundary that players must follow when serving. The rules and regulations for the service line include standing behind it when serving, not stepping on or over it during the serve, and ensuring that the ball lands within the opponent's service box. Failure to comply with these rules can result in a fault or loss of point.
Return first, unless you are a professional men's tennis player
In doubles tennis, the serving rules require the server to stand behind the baseline and alternate serving between the two players on the serving team. The server must serve diagonally across the court to the opponent's service box. The server must also wait for the receiver to be ready before serving and must serve within the service box. If the serve hits the net and lands in the correct service box, it is considered a let and the server gets another chance to serve.
In tennis, the rules and regulations for playing a service game include serving from behind the baseline, hitting the ball into the opponent's service box, and following the correct serving order. Players must also adhere to the rules regarding foot faults, double faults, and the number of attempts allowed for a successful serve.
In tennis, "30 love" means that the serving player has a score of 30 points while the opponent has a score of zero points.
