To verify a game-winning point, officials typically rely on technology and standard protocols to ensure accurate decisions. In sports like tennis, for example, the Hawk-Eye system is employed to confirm whether a ball is in or out. In other cases, such as basketball or football, referees may consult instant replay to evaluate potential game-ending plays. Verification aims to reduce human error and maintain the integrity of the game, ensuring that the outcome reflects the accurate flow of play and substantiates claims of victory.
