coz if u want to have some chance to finish a carrier someday, it's better to play in best of 1 set than in best of 3 sets most the matchs. With 1-set, u'll need at least 100 hours to achieve ur 16 years long career.
But if u prefer to play in best of 3 sets, then click on the icon of number of sets before the match, and u'll be all set..!
