Auto Chess is a strategy game that pioneered the auto battler genre, initially starting as a custom mod for Dota 2 in 2019 before being adapted into a mobile game. In Auto Chess, players recruit heroes, place them on a chess-like board, and then watch as the heroes automatically battle opponents in rounds. The game emphasizes strategic planning, as players must think about unit placement, synergies between heroes, and managing in-game resources to win. The genre quickly gained popularity, leading to several other auto battler games being developed.

The mobile version of Auto Chess retains much of the depth and strategic complexity of the original mod. Players can choose from a variety of heroes, each belonging to different classes and races, which provide specific bonuses when combined. The game also features ranked matches, allowing players to climb competitive ladders. Since its release, Auto Chess has inspired other games like Teamfight Tactics and Dota Underlords, but it remains a foundational title in the auto battler genre. Its success on mobile is due to its tactical gameplay, short match times, and the thrill of combining powerful units into winning strategies.
