A director asked: Which game format should my 6-team division play?
It depends on how many games you have promised each team. A common one: two brackets of 3, three crossover games each, then the two bracket winners play a final. For 4 teams, a round robin of 3 games each with the top 2 playing a final. The setup screen offers formats for each shape ranked by what your organization used before, and previews the games each one plays. Confirm formats only after your brackets are final; a format chosen earlier is often wrong by then.
