Very nice code, I see in your type 'Quit' to give up you could of made it more effective and simpler. Let's say they type qUiT the program does not know what to do. I would like for you to take a look of my guessing game when I first started out where I did the same concept. https://repl.it/@KEVINGRANADOS1/GuessNumber take a look on line 43 and try to experiment with it, it is much simpler and efficient.
