How many points must a team lead by to win a set?

In volleyball, a set is won by the first team to reach 25 points, provided they have at least a two-point lead over their opponent. This rule is crucial because, without a two-point margin, the game could extend indefinitely, especially in closely contested matches. For example, if the score reaches 24-24, a team must score two consecutive points to win the set, making it 26-24. This ensures that the game maintains a clear winner, promoting fair competition and strategic play. If a team were allowed to win by just one point, the potential for ties at crucial moments would create uncertainty and affect the integrity of the match. Therefore, the requirement for a two-point lead is essential for concluding a set in volleyball.
