Blocksworld is a physics-based 3D sandbox video game developed by Linden Lab originally for the iPad on July 26, 2013. It was later released for the iPhone on 2016, and later, for Steam on September 25, 2017. As of 2020, Blocksworld is absent from Linden Lab's website (excluding previous press releases), and servers were fully shut down June 17, 2020. It was subsequently removed from the App Store afterwards, and was later pulled from Steam on July 2, 2020.


In Blocksworld, players could build from 3D building blocks that could be combined to construct simple or complex creations. Players could also use "action blocks" and a drag-and-drop visual programming tool to add interactivity and gaming to their creations. Examples included drivable cars, flyable jets, and playable games with win/lose conditions, health systems, and other attributes.
