Q. I don't have any Google Play or Apple ID to connect.

A.

To protect your game data, you need to link your accout to either Google Play or Apple account.

We strongly recommend you play the game after linking it, 

as there is a high possibility of data loss in Guest account.

Please note that there is no possible way to recover Guest account when data loss happens.

Also, you cannot transfer your data to another device when using Guest account.
