How to completely remove app?

I downloaded TapTap revenge 4 to my iPhone. I accidentally messed up and created a new account instead of transferring an old one. So I deleted it and re downloaded it but all my account and data was still there. How can i COMPLETELY remove all data of an app from my iphone?

You have to remove it from the game center

Burn your iPhone and any other devices which are connected to it via iCloud!
