          Args:
            number_fresh:  integer, number of new fresh games needed
  
          Increments the cell `table_state=metadata:wait_for_game_number`
          by the given number of games.  This will cause
          `self.wait_for_fresh_games()` to block until the game
          counter has reached this number.
