Game Center was, at one, progressive. It enabled users to play games with friends. When games like Fruit Ninja were very popular. You could challenge your friend and try to beat their scores for any game that supported it. From that point onward, Game Center hasn’t really had any improvement much. Some of the best Games in iOS like Letterpress and King of Thieves have their own matching engine that can discover players from around the world to play with. Facebook integration also makes it more easier to challenge friends regardless if they’re playing on a different platform. With that said, Game Center seems to have lost its usefulness. Unfortunately, up until iOS 10, there was no real way to turn off the Game Center. If you signed out, a banner alert would request that you sign-in each time you launch a game. Thankfully, iOS 11 gives you an out.
Turn Off Game Center
To turn off Game Center in iOS 11, open the Settings app. Scroll down to Game Center preference, and tap on it. On the Game Center screen, turn the ‘Game Center’ off. When you next launch a game, you won’t be asked to sign into Game Center.
Signing Out vs Turning Off
When you sign out of the Game Center, the feature is pretty much still active. It will poke you whenever it can to sign in. This poke comes as a form of a banner which can actually take some time to show up. More often, it shows up when you’re ready to start playing your game. It will most likely obstruct gameplay at a crucial moment in the game.
When you turn off Game Center, however, the banner never again show up. Your game achievements up to this point aren’t lost but any new achievements and scores aren’t stored in your account. If the game(s) you play support Game Center, you may have the ability to synchronize new achievements to Game Center by signing in once again.
Game Center does not play a part in saving game progress. In case you’re playing a slightly longer title like the Infinity Blade series or Movement Valley, your game progress is saved inside the game. To go back up your game progress, all you have to do is backup your iPhone with iTunes.
Some of the games that sync over an online server like King Of Thieves synchronize progress over your own account ID or via iCloud. In such a case, you won’t need to backup game progress. Check your game for any in-game saving options.If you can’t find any, an iTunes backup is always the best way.
NB: iOS 11 is still currently in beta. The stable release is expected to arrive in September/October 2017.
