How do I update apps that I didnt purchase?

[hackanapp]

OK, I admit it. A friend gave me a few games that he had bought. I installed them but I cant update them and I get a message that I cant because I didnt purchase them. Is there a way around that besides buying them?

Log in to his google account is my best guess

There is a way! You purchase the apps and you get updates!!
