As a side, I gave up on that game. It was no longer fun. The entire game revolves around you getting more and more friends and picking the right traits at the beginning. So sure, if you don’t mind having 1000 fake friends in your Facebook account, it’s a great game. But for people who actually use facebook, there is no real way to win. And thus I gave up, gifted out my stuff, and tried to pry it from my account, eventually having to block it to shut it up.
If you want to add more friends though, go to their forums, you’ll find a huge paragraph of emails to add and become friends with. But it will take lots of time to clean up your facebook account and everyone will see you having millions of friends. If you’re OK with it, then it’s easy to win that silly game.
