As indicated already in our Forum and in our community, Miniclip strongly suggests upgrading any Guest account to avoid any data loss. Why?
Imagine the following scenario:
There you are, shooting hoops in your favorite basketball game, Basketball Stars, when you lose your Guest Account! Oh no, that's not good. What now?
In most of the cases, there is no way for us to recover your Guest Account, so it's lost forever. But fear not, if you link your game to a Facebook account, you'll be safe.
How can you link your account?
If you access your settings, you'll see a small "Login" icon.
Choose the login type you prefer: "Login with Facebook" (available on Android and iOS devices) or “Sign in with Apple” (available only on iOS devices).
Very important: Make sure your Facebook or Apple account was never used before in this game, or else this is not going to work.
That's it, the account is now saved. Enjoy our game!
