Battle of Balls

Battle of Balls (《球球大作战》) is a casual competitive multiplayer mobile game from Giant Network — a match pits 10 teams of 5 players against each other, demanding heavy in-game coordination — and one of China's rare long-lived, high-DAU hits, reaching tens of millions of daily users purely through organic growth under team lead Wu Meng . It's also become an unlikely AI proving ground: Hyperparameter's Yongsheng Liu told 高榕 in 2020 that his team partnered with Giant to train AIs with teamwork, competition, and long-horizon planning skills inside the game, with some players already matched against AI opponents . Its lineage is still producing hits — per a Monolith砺思资本 piece from August 2025, Giant's recent performer 《超自然行动组》 grew directly out of the Battle of Balls team, with the two sharing a continuous creative approach .
