So, we did it, 30 players with 3 player teams. It was fun, 4 rounds of swiss!
The event was created at ABR as team event, so it’s possible multiple players claim the same spot. Not ideal, but okish
On top we used Tome for the tournament and it worked like a charm. You can add points manually like 12 - 1 or whatever the results are and it will do the next swiss round based on it. 3 player KOS, 4 players doesn’t matter.
On top of that, http://cobr.ai/ should also work for KOS.
