The site will indicate the player(s) whose tiebreak selection is closest to the combined total of the last game of the week, as indicated on the pick sheet. (NOTE: It is the tiebreak value closest to the actual value, NOT closest without going over)

If two members tie in points and have the same points in a tie breaker the site would consider them tied. As the commissioner you can create a custom rule to do your own tie breaker and have this posted on the dashboard/messenger.
