HI all i m having some trouble concluding the run_game method as well. it asks for the card and stops when busted. the trouble is it doesn't recognise the "stick", it will go on and on until busted it doesn't matter if the input is stick or hit:

def random_card
  cards = ["two", "three", "four", "five", "six", "seven",
           "eight", "nine", "ten",
           "jack", "queen", "king", "ace"]

  cards[rand(13)]
end

def move
  puts " hit or stick"
  user_move = ''
  until user_move == "hit" || user_move == "stick"
    user_move = gets.chomp
  end
  user_move
end

def score(list_of_cards)
  cards_to_number = {
    two: 2,
    three:  3,
    four:  4,
    five:  5,
    six:  6,
    seven:  7,
    eight:  8,
    nine:  9,
    ten:  10,
    jack:  10,
    queen: 10,
    king:  10,
    ace:  11
  }
  sum = 0
  list_of_cards.each { |card| sum += cards_to_number[card.to_sym] }
  sum
end

def run_game
  list_of_cards = []
  input = move
  while true do
    if input == "hit"
      list_of_cards.push(random_card)
      puts "Score so far: #{score(list_of_cards)}"
      move
    elsif input == "stick"
      puts "You scored: #{score(list_of_cards)}"
      break
    end
    if score(list_of_cards) > 20
      puts "You busted with: #{score(list_of_cards)}"
      break
    end
  end
end

Hi Antonio, the problem is you are only asking the input once so it is always gonna be the first one asked for. You should put your move inside the while loop.
Let me know if it works :)

i sorted it : i have saved the move into input within the loop and it worked :)

def run_game
  list_of_cards = []
  input = move
  while true do
    if input == "hit"
      list_of_cards.push(random_card)
      puts "Score so far: #{score(list_of_cards)}"
      input = move
    elsif input == "stick"
      puts "You scored: #{score(list_of_cards)}"
      break
    end
    if score(list_of_cards) > 20
      puts "You busted with: #{score(list_of_cards)}"
      break
    end
  end
end
