Thinking. Getting 14538. Something's wrong there. I think.

OpenStudy (mathmagician):

your answer is good. Since there is only one winner of tournament, 14538 players must be eliminated.And this requires 14538 games to be played :)

Yes. It's correct? Haha. Good question. :) Confused me for a bit there.
