In the last few months we've seen the sudden arrival and widespread popularity of a new genre: Auto Chess. The original, created within DOTA 2's internal mod toolset, took that game's signature heroes and sprinkled a bevy of mobile game mechanics to create something new. You use coins to buy heroes, you place those heroes on a chess board, and then they battle automatically against other player's heroes. You as you progress you get more coin to spend on getting more heroes, you combine extra copies of your heroes to create stronger versions, and you get items that can boost anywhere from one hero to your whole squad.
