  total_score = 0
  def miniscore(n, c)
    triple = n * 100
    single = 0
    if n == 1
      triple = 1000
      single = c >= 3 ? (c-3) * 100 : c * 100
    elsif n == 5
      triple = n * 100
      single = c >= 3 ? (c-3) * 50 : c * 50
    end
    if c >= 3
      return triple + single
    else
      return single
    end
  end #end miniscore(n, c)

  for n in dice.uniq
    c = dice.count(n)
    total_score += miniscore(n, c)
  end
  total_score
