Super Starfish’s Leagues require you to be logged into a Game Center account on your phone.
1) Ensure you are signed into Apple Game Center.
On your iPhone navigate to the Settings section. Scroll down and click on the Game Center item.
Make sure that the Game Center slider is set to ON.
2) Open Sling Kong
Now that you have a Game Center account, simply re-start Sling Kong. Sling into the opening to the left and you should now be able to access and sign into the Leagues Feature.
