I know how to use a `while` loop, but I'm not sure about the part where I need to make a command to double the previous score.

[The task](http://i.stack.imgur.com/rPz5g.png) is to double or quit.

And this is my current code :

```
import random
play = 'y'
Original = 1

while play.lower() == 'y':
    chance = random.randint(0,3)

    if chance == 0:
        print("Unlucky.... better luck next time")

    else:
        newnumber = Original*2
        print (newnumber)

    play = input("Play again?[y/n]: ")

```
