Finished guess.rb

I managed to work through most of the program, but I had trouble with my "guess counter". It seemed like the program wasn't keeping track of the number of guesses the user input. Therefore, my program will not stop after 3 guesses, it will keep going until you answer correctly. I also know that I repeated myself in some places and need to find better methods of refactoring to keep my code DRY! 
Here's your problem - this should be guess_count += 1. That's why it wasn't incrementing, and why you couldn't get out of the loop.
