I completed the game and want to start over because I enjoyed it. Unfortunately, it’s connected to Game Center and I can’t erase my data. Is there a way to erase my data and start over?
Since the release of iOS 10, all of your Game Center data is now stored in iCloud.
To remove all of your game’s data, try the following:
- Tap on Settings > Apple ID Profile > iCloud
- Tap on Manage Storage.
- Look for the game in the list of apps that iCloud backs up data for and tap it.
- Select Delete Data. Note: This will delete all data for this game from all Apple ID connected devices.
hope it helps
