What is the six-again rule?

The Rugby League World Cup will get underway this weekend, and for the most part, there is little to worry about in the way of rule changes.

However, there are a couple of specific rule changes that you will need to be aware of if you haven't kept tabs on the sport since the 2017 RLWC.

The main one is the six-again rule, which has featured in the NRL and the Super League for the last two years. Here is what it means and how it is used.

What is the six-again rule?

The six-again rule was first introduced in 2020 in an attempt to speed up the game. Its introduction meant that teams would receive a set restart, or 'six again', for infringements around the ruck.

A six-again can be awarded for any ruck infringement when the attacking team is less than 40 metres from the opposition's try line.

Any ruck infringement within 40 metres will result in a penalty as per the traditional rules.

There is no limit to the number of times the six-again rule can be enforced. However, referees are more likely to award a penalty for consistent infringements in the ruck.

How is six-again indicated?

A referee will indicate the awarding of a set restart - six-again - by waving their right arm above their head.

In addition to this, a hooter will be sounded inside the ground to ensure that the players on the pitch are aware of the awarding of a new set.
