We are no longer updating the HD version of Bad Piggies and have removed it from the app stores. Old users can still download it via the past purchases section on their Google Play/Apple account. On iOS, you can find it from App Store -> Tap on the account icon in the top right corner -> Purchased.
On Android, you can find the app from Play Store -> Tap on the account icon in the top right corner -> Manage apps & device -> Manage tab -> Select the filter 'Not installed.'
You can continue to play the game as you always have on devices where it is available. Still, if you want to receive future updates, we encourage you to move over to the other version of the app, which is called 'Bad Piggies.'
Game progress can be transferred to the supported Bad Piggies app by syncing your data to the cloud via Facebook login or Sign in with Apple (iOS only). Once progress has been synced via the settings menu (you will see a popup and a red logout button), you can uninstall the HD version, download and launch the 'Bad Piggies' app, and log in there to continue from where you left off.
Please note that if you have earlier used Facebook or Apple account in Bad Piggies on another local save, it will load the saved data linked into that account instead of moving your current local progress to the cloud. Confirm that your progress is where it should be after logging in. In case you loaded an old save from the cloud by accident, you can log out to restore the progress and try another syncing method/account.
