The rule at work here is that users can be awarded badges for a streak of 10, 20, and 30. If the user has a streak over 30, such as 40 or 50, then the logic must be that it only awards a 10-streak badge for 40 and a 20-streak badge for 50, and so on.

  def check_win_streak(streak)
    badge = 10
    while badge < badge::MAX_STREAK_BADGE_SIZE do # MAX_STREAK_BADGE_SIZE = 30

       if streak < badge then
         break
       end

       if (streak % badge == 0) then
         award_streak_badge(badge)
       end

       badge += 10
    end

end
