Divide group into two teams, both play in one (or two) thirds of court.
One team is hunting the members of the other team. The hunting team have
the ball and must tag the prey with the ball. The ball must be held by
a hunter when the prey is tagged (i.e. hunters cannot throw the ball at
the prey, although they can pass between themselves). Normal netball rules
apply, i.e. no stepping, bouncing etc. When prey get tagged they are out.
