The ladder match ranks are a friendly match tournament.
You compete on ranking lists to win credits. The tournament end when the season ends.
For each match you play your will earn points (or lose points). The point system is based on how many ladder points your opponent has. So if you play an opponent with a higher ladder match score that you, you will earn more points when you win that you will lose if you lose the match - and vice versa.
The start score a club will have when the ladder match tournament starts is based on your club's world rank. The higher you are on the club world rank list the more points you will start with in the ladder match ranks.
Players do not earn routine in ladder matches.
