The Facebook version of the game is still currently playable. 

We have decided to offer an alternative way to play our game on the web (Angry Birds Friends WEB) in order to provide a better quality service to our web playerbase. With our own website, we can provide: 

• A larger, scaleable screen. 🔎
• Reduced downtime and enhanced stability; having our own website for the game reduces our reliance on external dependencies like Facebook. 😌
• Secure platform - player data not to be shared with any third party (e.g Meta, Apple, Google). 🔒
• An alternative method for saving game progress (Red's Club). 🔗
• Lower device memory usage, which can result in better performance. 💻
