Blocksworld
Blocksworld was a physics-based 3D sandbox video game developed by BoldaiAB and Linden Lab released originally for the iPad on November 21, 2012, in Nordic countries and later worldwide on July 6, 2013. It was later released for the iPhone on 2016, and later, via 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 on June 17, 2020. It was subsequently removed from the App Store afterwards, and was later pulled from Steam on July 2, 2020. Gameplay

In Blocksworld, players could build using 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 to their creations. Examples included drivable cars, flyable jets, and playable games with win/lose conditions, health systems, and other attributes. Players could also upload their creations for others to play. Development

Blocksworld was initially developed by Swedish independent video game developer Boldai (originally named Creative Builder) which was acquired by US-based Linden Lab on January 24, 2013. An earlier paid version of the game was briefly available in 2012 in Sweden, Finland, Denmark and Norway for 28 Swedish Krona. Blocksworld was intended to be released worldwide on December 13, 2012, for US$0.99. This was later pushed back until Linden Lab's acquisition. For the subsequent global release, the game was repositioned as a freemium offering where players had the option to purchase premium sets and games, additional building objects and pieces, coins, and other upgrades and extras for a small fee. Legacy
Despite the servers shut down in 2020, the game still retains an active player base. Blocksworld: The Secondary Server, also known simply as Blocksworld 2, is an unofficial fan revival project which started in 2019. Fortell Games acquisition
It was rumoured that in August 2023, Blocksworld was acquired by Fortell Games Inc, a studio located in Kyiv, Ukraine, and Santa Monica, California, after it was noticed the games publisher changed on the Apple App Store. This was later backed up further when the Steam page was updated to list Fortell Games and "Blocksworld LLC" as developers. References
