Game Center

Hey there Pralayankar,

Thanks for reaching out to the Apple Support Communities.

You can change your Game Center nickname by going into Settings > Game Center on your iPhone, and then tap the Nickname shown. From there you can edit the name and after you tap the return key, it should save the new nickname for use with your Game Center account.

For more details, check out this link here: Play with friends in Game Center on iPhone - Apple Support

1. Go to Settings  > Game Center, then sign in with your Apple ID.

2. Do any of the following:

- Choose a nickname: Tap Nickname, then enter a name or choose one of the suggestions. Your friends see your nickname when you play games together.

We hope that's able to help.

Have a great day!
