Miniclip highly advises our customers to upgrade to connected accounts since these are not prone to data loss.
Data loss in Guest accounts can happen due to devices being lost, erased or restored, etc.
Please follow these steps to connect your Guest accounts.
1. Go to the Settings and select Manage
2. Select "Secure this profile"
3. Choose the login type you prefer: "Sign in with Facebook" or "Secure with Phone #"(available on Android and iOS devices) or "Sign in with Apple"(available only on iOS devices).
That's all it takes, now your account is linked to your Facebook or Apple ID account and you won't lose it.
Very important: Make sure your Facebook or Apple account or your phone number was never used before in this game, or else this is not going to work.
