What happens if during a serve the ball clips the top of the net In table tennis I want a nice detailed paragraph if you don’t mind.

During a rally, if the ball touches the top of the net and then otherwise lands as a legitimate hit. BUT not when serving. If a served ball hits the net on the way over and otherwise legally bounces in play, it’s a “let” serve and is done over. There is no limit on how many times this can happen.  If the ball touches the net and still bounces on your opponent's side of the table, the service must be replayed.

The umpires have several roles, including inspections, ensuring safety, giving decisions, and communicating. It is up to the umpire to ensure that free or penalty passes are taken where the infringement occurred. The umpire controls the game and the players. Without the umpire, the game could not take place. The game begins when the umpire tosses a coin to decide which team starts, and they stop the game by blowing their whistle. They stop the game when any team calls a timeout, if not then, they stop it when the game has finished.

Hope this helped!

Have a day!
