I want to take sniper 3d in my other mobile because I don't want to restart again. How do I do that?

First you must save your progress to GameCenter- you’ll have to link-it in your OPTIONS at the main screen of the game. THEN sign-out of the App Store, apple iphone, iCloud, sign out of your device completely. Once this is done, sign-in on your new device, Apple ID, GameCenter, AppStore, download the game again, open the game and you’ll get a notice to load your previous progress, after you chose that option- on the main screen go back to OPTIONS and hit the Reload on the bottom right from GameCenter. You’ll see all your progress load back up after a few blackout reset screens.
