Dota Auto Chess is a strategic game modification for the computer game Dota 2. Developed by Drodo Studio and released in January 2019, the modification supports up to eight players. Its popularity with more than 8 million players by May 2019 led to the recognition of the autobattle genre, which led to the release of other games in the series. Later in 2019, Drodo Studio developed a standalone version known simply as Auto Chess, and Valve Corporation, the developer of Dota 2, developed its own standalone version known as Dota Underlords.
