Ruby 红宝石21点和循环

我正在使用方法构建一个命令行ruby blackjack游戏。我已经到了玩家可以击球或持球的地步（在发了两张牌之后）。现在，我似乎无法从逻辑上思考如何将我的球员限制在四支安打以内。制造

这告诉我我的问题是循环-也就是说，我以错误的方式接近程序的循环部分

以下是我目前的代码：

def blackjack
  promt
end

def promt
  puts "Welcome! Would you like to play a game of blackjack? Enter Yes or No"
  play = gets.chomp.downcase
  if play == "yes"
    game_plan
  elsif play =="no"
    puts "That's too bad. Come back when you feel like playing"
  else
    puts "Sorry but I don't understand your respones. Please type and enter yes to play Or no to to quit"
    blackjack
  end
end

def game_plan
  wants_to_play = true
  hand = []
  total = first_move(hand)
  wants_to_play = hit_me(hand)
  if wants_to_play == true
    hit_me(hand)
  end
end

def first_move(hand)
  deal(hand)
  deal(hand)
  total(hand) 
end

def deal(hand)
  card = rand(12)
  puts "You have been dealt a card with a value of #{card}"
  hand << card
end

def total(hand)
  total = 0
  hand.each do |count|
    total += count
  end
  puts "The sum of the cards you have been dealt is #{total}"
  total
end

def hit_me(hand)
  puts "Would you like to hit or stick?"
  yay_or_nah = gets.chomp.downcase
  if yay_or_nah == "stick" && total(hand) < 21
    puts "Sorry! The sum of the cards you have been dealt is less than 21. You lost this round!"
  else
    deal(hand)
    total(hand)
    playing = true
  end  
end

你在找这样的东西吗

MAX_HITS = 2
hits = 0
loop do
  break if hits > MAX_HITS
  puts "Would you like to hit or stick?"
  …
  else
    hits += 1
    …
  end
end
