Serving team has 2 attempts per point, same as in Tennis.
Serving player needs to be behind the service line, serve in diagonal and the ball should bounce first on his floor and then hit below the waist.
Ball should end on the opponents box and should not touch the wire mesh side after the first bounce.
Point system it’s exactly the same as Tennis: 15; 30; 40; Point or Deuce.
A set is won when a team collects 6 games and there is at least 2 games difference. If the score is 6-5 set is extended for one more game, if the outcome is 6-6 then there is a 7 points tie-break.
