I have a new phone (old one died), have logged in to my King account successfully, but nothing of my prior games has been restored even though after logging in it said they would be. I have never logged in to Facebook in the games. I would assume this wouldn't be necessary for King to record my games. If the games can't be restored (was at 600+ on CC) then I would not start replaying them and doubt I would ever play a King game again.
