What happens when the ball hits the net but goes over during a serve?

When the ball hits the net but successfully crosses over during a serve, the play is considered valid, and the serve counts. This situation is a common occurrence in volleyball and is known as a "let serve." According to the rules, as long as the ball passes over the net and lands in the correct service area, it is treated just like a standard serve, and play continues. This rule applies regardless of whether the ball touches the net or not, reflecting the flexibility and fast-paced nature of the game.

In contrast, other options, such as repeating the serve or declaring the ball out, do not apply in this context since the ball has successfully entered the playing area, thus maintaining the flow of the game.
