 The "quinze" begins when a player serves by bouncing the ball in the "dau" square (if in a trinquet) or on a marked stone from the "fault line" (on a street).It doesn't matter if the ball bounces on the ground as many times as needed.But, in the case the match is played in a trinquet, if the ball rebounds on the "rest" or "dau" walls it must be thrown back after the very first bounce (if it didn't bounce yet) or when it's on the air (if it already bounced).
