Have teams face off against other random teams. Scoreholio will prevent teams from playing the same team twice all while keeping a running leaderboard. Take the results and create a seeded bracket.
With Scoreholio's Round Robin format, you set how many rounds you want players to play before going into a finished/not playing section. We have an entire blog section dedicated to how to set rounds here: Blog
To break it down quickly, remember these rules:
You can check out the same blog from above for more info. To break it down, just know it is best to have at least 3 people or teams NOT playing at a given time. Scoreholio will ALWAYS fill a court that is open if it can. To prevent players from just playing back to back to back on the same court, have players or teams in the comping up section.
