Game Center

Hi aaronfromshenandoah,

Welcome to the Apple Support Communities!

We understand that you no longer see Game Center on your iPod touch after updating to iOS 10. In iOS 10, the Game Center application has been removed, but you can still manage your Game Center settings by navigating to Settings > Game Center.

Have a great day

YOu can basically sign in and sign out via the settings. The adding of friends must be done through the game itself. None of the games that I have that allow for friends have implemented this yet. However, as i understand it, adding friends will be done through the individual game interface and involve the use of iMessage.

Nothing I've read makes any mention of removing individual friends and in the settings all you have is a remove all option.
