hope this makes sense.
Points go as follows
0
15
30
40
win
Player has to win by one more point than the other.
Only situation this is different is if score reaches 40 -40. This is called deuce. They then play two more points.
Advantage
win
However, if you get to advantage then los next point it goes back to deuce until someone wins 2 straight points.
Wimbledon has 5 sets in a men's match and 3 sets in a womens. You must win a set by 2 games having won either 6/7 games ie 6-4 or 7-5.
If it reaches 6 games all, it then goes to a tie break game where the first to get to 7 points with a 2 point gap wins. However tiebreaks go on until there is a 2 point gap, no deuce like in normal game so it could go up to 13 - 11 for example.
To win a match you must win 3 sets in a mens match and 2 in a women's
Only other thing i can think of is that in the final set there is no tie break you just keep going until someone has a 2 game lead.
Phew, too much brain power used there. Need a lie down
Hope it makes sense.
