To log in to your club, just make sure you are connected to the correct account.
If your account has not been connected to Facebook / Game Center / Google Play, you must open the club on the device on which it was created and enter the game through the "Guest" option.
You can log out at any time to access the login screen. We remind you that you need to link your game accounts to Facebook or Google. Playing on a regular basis as a Guest is not safe.
It is also necessary to have screenshots of the profiles of your game accounts, where the ID is written: this is the key to quickly restoring a lost account.
