Game Center saves my Clash of Clans account? 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.
If you have agreed to connect your Game Center account with Clash of Clans then yes, your progress is saved when swapping devices.
