Zachtronics is an American game development studio based in Redmond, Washington, founded by American video game designer and programmer Zach Barth in 2000. The studio is known for innovative puzzle games, often involving programming logic, like Infinifactory (2015) and SpaceChem (2011). Zachtronics was acquired by Alliance Media Holdings in 2016 as a subsidiary design studio, retaining Barth as lead designer, and the studio has continued to develop puzzle games in the same vein.
