And the biggest rule for scoring is to call out the serving team’s scores first. Each game will consist of 4 points: Love, 15, 30, 40, and Game. No score―love, 1st point―15, 2nd point―30, 3rd point―40, and 5th point―game. This sounds pretty simple; as the teams score points, they get closer to winning the game in a set.
