In tennis you have a tie break how do you win the game?

Basically, to win you have to win 7 points and have a clear lead of at least two points. So for example, if you are leading 6-5 and you win the next point, you win the tie breaker 7-5. However, if you lose the next point, the score is 6-6 and then to win, you need to win the next two points, to make it 8-6, a lead of two clear points. And so on. scores have been known to go up to 24-22 etc. Also if you want to know, the serving is like this - the person who started serving in the set serves first. S/He serves once, then the opponent serves twice, then they alternate two serves each. If you win a point on your opponents service, this is called a mini break, and after every 6 points, you have to switch sides of the court
