A Dota 2 custom game mode designed by China-based Drodo Studio is taking the Dota 2 world by storm, reaching 100,000 concurrent players earlier today and racking up over 670,000 subscribed users. Dota Auto Chess is a strategic, tactically complex mix of board game and Dota custom map. Play is based around drafting hands of heroes, combining them to upgrade them, and then deploying them correctly to win victories over eight other players in a series of one-on-one matches. The game has become wildly popular, with more concurrent players today than, say, Grand Theft Auto 5 or Football Manager 2019. Like Dota 2, Dota Auto Chess is completely free.

Dota Auto Chess is a weird name for it, I’ll grant. That makes sense since it’s cross-cultural, but the game doesn’t really have that much to do with a match of chess other than an 8x8 board. In truth, it inherits more from tactical board games like Neuroshima Hex or Warcraft 3 mods like Legion TD and Hero Line Wars.
