I can’t link my guest account to game centre

Hi @MARKUS182008, 

First let's make sure you're signed in to Game center: 

1. Open your phone or tablet’s Settings.
2. Find and tap on Game Center.
3. Tap Sign in and enter your Apple ID and password.
   • If you’re already signed in, you’re ready to connect your game.

Once that's done, follow these steps to connect your game to Game Center:

If you signed in to Game Center on your device, the game should connect automatically. You can check your game settings to be sure.

1. Tap the arrow pull-out tab on the right side of the game screen.
2. Tap the Settings cog tab.
3. If you see the message, "Sign in to Game Center to play on other devices", tap the Connect button.
   • If you don’t see it, congratulations! You’re connected.

These steps should do the trick for you. 🙂 Let us know how you get on. 

Thanks,
