In this game there are 3 players, a front player (say A) and two players (B and C) at the back occupying a rear quarter each. The front player must play all her shots into the rear half and the two players in the rear of the court must play all their shots into the front half.
Play is started by one of the rear players delivering a boast serve from behind their service box to the front opposite corner. A moves from the T and plays the ball in to the rear with a drive or lob, straight or cross court. Drives can be towards mid court side wall nicks if wished but must arrive first bounce in the rear half (unless one of the rear players judges it to be in and volleys before the bounce). Depending on which rear quarter the ball lands in either B or C will play the ball anywhere into the front half of the court. This can be a boast, or drop and can be driven firmly as long as it does or would land in the front half of the court first bounce. After each rally the serve alternates from side to side of the court. Players B and C occupy their quarter at all times and the froward player A stays in the front half.
Rallies are scored with whoever plays the winning shot getting a point. Generally speaking the advantage is assumed to be with the forward player who is in the attacking position. When one of the players reaches an agreed score (say 9 or 11) they have won that game and the players rotate one place clockwise or anticlockwise so every one gets a chance to play in both the rear quarters and at the front.
This game encourages the front player to play deep tight straight lengths or high dying lobs. By playing tight, limiting the rear players options and watching them at all times the front half player should prevail most of the time. The rear players are looking for anything that is falling short or not tight that they can drop to the front or whip cross court to the opposite side wall nick. Volley drops cut off just behind mid court can be very effective for example. When the player at the front plays down the centre of the court the rear players need to be quick to react and decide whose quarter its falling in and therefore who should play it. If the correct player fails to play it and return it correctly, they have lost the point.
All players should move up or back towards the T after executing their shot so they can react and get into the correct position for their next shot which, for the front player, can be from anywhere in the front half and, for the rear players, anywhere in their particular quarter.
