This document summarizes some key rules for badminton: 1) A "let" occurs if the server serves before the receiver is ready, both players are faulted during service, or the shuttle gets caught on the net or in the net during play. When a let occurs, the last server serves again without the previous point counting. 2) The shuttle is not in play if it strikes the net and falls on the server's side, hits the court surface, or a fault or let has occurred. 3) Play is continuous from the first serve until the match concludes, with intervals of 60 seconds allowed when a player reaches 11 points and 120 seconds allowed between games.
