The first edition was a double elimination knockout with eight competitors. The second edition was a single elimination.
The inaugural 2019 tournament was won by Xie Erhao. This was a triumph of the double elimination system, since Xie had lost his first game to Tan Xiao, and had thus had to win his way through the losers' tournament in order to face and beat Fan Tingyu in the common final.
