Players are effectively playing a game of touch-doubles, so the ball is fed in and the point played out within the service boxes, with the tramlines being out. Players must use touch and feel as no pace or power can be use to win the point. They can volley and the ball is allowed to bounce as in normal tennis. However, each player only has to look after their own service box quarter. Balls which land in their zone are the only ones they are responsible for retrieving. If they so wish, they can poach and intercept balls in the other players' box, but the player next to them is not going to cover their back and switch sides as in normal doubles.
