How does the tie-break work in beach tennis?

The tie-break is played to 7 points (win by 2) when the set reaches 6-6. The serve rotates after the first point and then every 2 points per ITF Rule 8b. Players change ends after every 6 points in the tie-break.

Full Explanation

Per ITF Beach Tennis Rules Rule 8b, when the set score reaches 6-6 a tie-break game is played. The tie-break is scored as individual points (1, 2, 3...) rather than 15/30/40. The first side to reach 7 points with a 2-point lead wins the tie-break and the set (7-6). Service in the tie-break: the player or pair whose turn it is to serve in the normal order serves the first point from the right (deuce) side. After the first point, service rotates every 2 points in the sequence: 2 points served by the next player in order, 2 by the next, and so on. Players change ends after every 6 points in the tie-break. At the end of the tie-break, the player or pair that received first in the tie-break serves first in the next set.
