*Swiss is a cup system where you won't get kicked out of a Swiss cup after your first loss, you will stay in the Swiss cup until a certain loss-threshold has been reached or the cup has finished. Every Swiss cup has a fixed amount of rounds. In every round you will be matched against opponents of your skill group, based on the current player score (for example, players who have a 1-1 score face others with the same score). A ranking will be shown at the end of the cup based on the points of every contestant's performance.
