In volleyball, a team must win by at least 2 points when the game is played to a specific point total. The most common scoring systems are:
- Traditional Scoring (used in some levels): A team must win 15 points and lead by at least 2 points.
- Rally Scoring: The team must win 25 points and lead by at least 2 points. This is the standard in most modern competitive play, including professional and collegiate levels.
- Final Set: In a deciding set (such as the fifth set in a match), teams typically play to 15 points and must still win by 2.
So regardless of the scoring system, a team must always win by a minimum of 2 points.
