About Game Center
You can discover new games and share your game experiences with friends around the world in Game Center (iPhone 3GS or later). Invite your friends to play, or use auto-match to find other worthy opponents. Check leaderboards to see who the best players are. Earn bonus points by achieving specific accomplishments in a game.
Note: Game Center may not be available in all countries or regions, and the available games may vary by country or region.
To use Game Center, you need an Internet connection and an Apple ID. If you already have an iTunes Store, MobileMe, or other Apple account, you can use that Apple ID with Game Center. If you don’t already have an Apple account, you can create a new one in Game Center, as described below.
Setting Up Game Center
When you first open Game Center, you’re asked if you want to allow push notifications. (You may first be asked if you want to turn on Notifications.) Notifications may include alerts, sounds, and icon badges that let you know about Game Center events even when you’re not using Game Center. For example, you might receive an alert that a friend has invited you to play a game.
Allow notifications: Tap OK.
If you tap Don’t Allow, you won’t receive notifications for Game Center. You can turn notifications on at a later time if you want, and you can specify what kinds of notifications you want to get.
Turn notifications on or off: In Settings, choose Notifications. Turning off Notifications disables all notifications for all apps.
