This is similar to the progressive 3/4 already described but starts just in a rear quarter only. When a player gets to 5 the front quarter adjacent to the rear quarter comes into play for all players, i.e the full side half. When a player gets to 10 the ball can be boasted into the other front quarter but must be returned to the original side half. At 15 the full 3/4 court game can be played. at 20 the game is finished and can be swapped to the other side of the court.

The game can be made harder if, up to 15 all shots must be played into the narrow channel, including the return of boast.
