Adding random friends
Is it possible for you to add random people's towns to your friends list?
Once connected through Game Center, Google Play, or Facebook you can visit your friends’ cities.
If you aren't connected socially or don't yet have any connected friends, you will still see your neighboring mayor, Daniel.
