How was the scoring pattern in tennis set?

Answer 1

It's kinda hard to explain, but...

There's 15-0, 30-0, 40-0, and then game. So you have to win four points in order to win a game. If it becomes 40-40, it's a "deuce." If you're playing regular scoring, you have to win two more points (in a row) to get the game. If you're playing no-ad scoring, it's a "sudden death point."

Whoever gets six games first wins. However, if you get to 5-5, you play "win by two games." If a player gets to 7-5, they win the set. If they win 6-5, and then lose the next game to become 6-6, they play a 7-point tiebreaker. (Whoever gets to 7 points first. If it becomes 6-6, you play until somebody wins by two.)

Same goes for the second set. (Juniors play best of three sets, so if you win the first two sets, you win the match. If you win the first set, but lose the second set, or vice versa, you play a third set OR a third set tiebreaker, which is a 10-point super tiebreaker. Most tournaments on the USTA Open & below level play 10-point tiebreakers as the third. More advanced tournaments like championships, excellences, etc. have a full third set.

Hope that's not too confusing...

15, 30, 40, game. If both players reach 40 its called deuce and the next point won is one players advantage. Once someone wins two points in a row at deuce, they win the game.
