Teams play each other in a home and away round robin. However, they do not all start with 0 points.

The only difference with European play-off of Super League is that this number is then divided by four (instead to five in Super League), to give the other teams the points with which they start the mini-league. If necessary, points will be rounded. As a result, the teams will start the promotional play-offs with the following number of points: Also, the teams will start the relegation play-offs with the following number of points:
