Some of the older ||Angry Birds|| games have remained unchanged for quite some time while we have focused on our newer titles. Rather than continually updating these older games to stay compatible with changing devices and marketplace requirements, we have focused on providing incredible experiences in our active games instead.
This means these games will no longer be available for download to new users. We are thrilled that our fans are so passionate about our games, and we are working hard to meet your expectations with our active titles. We recently informed our community that we are doing our best to return some of the older games! Please read this link for more information: https://www.rovio.com/articles/a-letter-to-our-fans/
If you have previously downloaded any of our older titles, you can check the following links, which outline how to re-download them.

If that is not possible, plenty of other great ||Angry Birds|| titles, such as ||Angry Birds 2||, ||Angry Birds Friends|| and ||Dream Blast||, are available.
