The various ways to find and log in to your player profile are described in detail on the individual help pages of the respective games.
If you already have experience with the player profile, follow these simple steps to log in to an existing account:
1. Launch the app
2. Open the menu and select the profile
3. Scroll down in the profile and tap on “I already have another account.”
4. Enter your old username and password and confirm
Exception: In Checkers, the player profile is backed up via email or Facebook and can only be restored via these.
