Enter this activation key into the "Activate full version" dialog box in the game to unlock all of the levels, golden egg extra content and any
available content updates.
When we release an update for a game, you should be notified the next time you start the game.
This is dependent on your computer also being connected to the internet. On your screen the notification will tell you that a new version of
the game is available, and it will ask you if you wish to update your game. If you choose not to update your game there and then,
you can always click on the download icon in the bottom left hand corner of the menu screen at a later time.
Take good care of your activation key - we recommend printing it out and storing in a safe place.
If you register at shop.angrybirds.com before you purchase your activation key, you can find the activation key from "your account" page.
However, if you lose your key please e-mail firstname.lastname@example.org for further instructions.
