Angry Birds Halloween

Angry Birds Halloween is an Angry Birds game created by Rovio and runs on Flash. It was released on October 31, 2013, and the online servers will shut down on December 31, 2020 because Rovio is not willing to convert the servers from Adobe Flash to HTML5 as the player base for this game is very low. The offline version will stay online, but after January 1, 2021, it will no longer be updated and it will be pulled from the App Store and Google Play Store in 2021.
