South Africa, New Zealand, Australia and Argentina meet home and away across six rounds of the Rugby Championship. The Springboks bank four points for a win and can add a bonus for four tries or a seven-point defeat; the side top of the standings once every team has played its six matches lifts the trophy.
There are no playoffs. South Africa, New Zealand, Australia and Argentina play each other home and away, and the team with the most log points after six rounds is champion.
A win earns four log points and a draw two, with a bonus point for a four-try match and a losing bonus for a defeat within seven points.
