Blocksworld is 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.

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.

Examples included drivable cars, flyable jets, and playable games with win/lose conditions, health systems, and other attributes.

[5] Blocksworld also included a feature where players could redeem a certain number of in-game coins for real money.

[2] Prior to its shutdown in 2020, Linden Lab paused development and promotion on Blocksworld, with its last significant update having been released in March 2018.

This was later backed up further when the Steam page was updated to list Fortell Games and "Blocksworld LLC" as developers.

[22] As of December 17, the website now shows a blue background and bouncing icons, some being direct links to the game's social media pages and merch store.

[25] On December 20, the official Blocksworld YouTube channel received its first upload in six years, showcasing several vehicles created within the game.

[26] Further activity continued, including multiple comments made on Reddit by a developer's account,[27] and various YouTube Shorts on the aforementioned channel.

[28] On April 3, 2024, a Steam community post was released by Fortell Games, announcing a Kickstarter to begin development.
