This question already has an answer here:
I going to sell my iPhone. I want to know if all my progress in Clash of Clans will be saved within Game Center so that I can recover everything when I buy a new iPhone and login again in Game Center.
- Assume I am correctly logged in the Game Center with my Apple ID
- Achievements are visible in the Game Center app
I'm level 18 and have 790 trophies and I don't want to lose that progress.
