The first player to reach seven points wins the tie-break and the set.
But if the score reaches six-points-all, the winner is the first player to win two points in a row.
The player whose turn it was to serve in the set serves the first point of the tie-break.
Their opponent serves the next two points and after that the serve rotates after every two further points.
The players change ends after every six points, even if a player is between his two service points, and at the end of the tie-break.
A tie-break is played in all sets except the last one (the third set in women's tennis and the fifth set in the men's game).
In the last set, players continue until one secures a two-game lead.
