To play, it is enough to simply enter the application – this creates a guest account. The guest account is linked to your device and can be lost if your device is lost or corrupted, if the OS is reinstalled on the device or if there is a system error on the device. We recommend that you register an account using your email address or Facebook account. By registering, you ensure that your game progress will be saved. Please note that only an account registered to an email address has a password. If the email address you initially provide is unavailable to access, it will be very difficult to reset your password or gain access to your account if you forget your password.
