City Flip Question;
I have had cities flip over to me before, but I've never really paid attention to how it worked, it was always just a city that was on my strongest cultural border and it wound up coming over to me.
This time around I've paid special attention to this one city (it has an Iron resource) and I've got a spy in the city. I've got it surrounded by culture, and 80% of the population is my Civ, but it is still under Zulu control. In the past I've just gone to war and taken the city, but this time I'm trying to figure out how to just get the city to flip to me since i've never done it actively. I sent a spy in a few turns ago, and incited the one turn revolt. I have the next spy en route. If I incite revolt again will it make the city flip? Thought I remembered reading somewhere that if a city revolts twice it will flip, or do I need to do something else beside the revolt? I really don't need to push culture since I've got it surrounded anyway but wasn't sure how to get it to flip. Hope this makes sense. Thanks.
PS - This was a city Shaka founded himself. He slipped through a hole in my early culture border and founded it on top of the iron so I've never actually owned the city, it's just mostly filled with my people, and surrounded by my culture.
