can someone explain this mode to me? its one scoreboard for all but not everyone faces everyone?
In a Swiss tournament (NOT round robin) there are a fixed number of rounds (usually the same as a single-elim bracket would have). Each round you take all of the people who have the same win/loss record and pair them up. So in a long enough tournament you tend to start playing people closer to your skill level.
The plus side is that everyone plays the same, fixed number of matches. The downside is that there are usually a lot more matches in a tournament so unless you have a large setups-to-player ratio it can take a really long time.
The other downside is that usually you have a lot of people finish with the same record, so it then goes to tie-breaker points which tend to leave people feeling cheated. (Normal tie-breaking system is to add up all of the wins of the people you played against, sometimes throwing out the top and bottom one or two. So the person who played stronger players has better tie-breaks, but that's not really something you have control over and can go counter to a head-to-head result.)
