The flowchart has two distinct versions to cover the rules discussions and updates from the designer. The new official rules are in the flowchart below, to be nice and simple for the profiteer.

This one is an alternative flowchart, which accentuates the difference between profiteer and boss. In this case, the Boss is considered part of both green and blue digging teams, while the Profiteer is only part of the single winning team. It's a subtle distinction, but it changes a few of the weirder cases in the flowchart.

This version is my personal preference, it should be considered a variant because it was not the final decision in the designer's poll thread as mentioned in the caption below.

This is the finalized flowchart for determining the winners.

It is based on the rules as written, and on the discussions in the rules forum, but with a focus on two threads: designer asks for input on rule clarification and discussion for Yargo's awesome player aid.

The profiteer's special cases are based on the idea that the "profiteer always wins" - this was the consensus built by the designer's poll in the first thread mentioned above. The support for this is that it keeps the rules as simple as possible.
