ByteDance’s TikTok is testing in-app gaming features in Vietnam, which it hopes will boost its advertising revenue, according to Reuters. The firm has been testing web-based games from third-party developers in its app, a TikTok representative told Reuters. The report also cites sources as saying that TikTok plans to expand its gaming services in Southeast Asia, possibly making a big push in the sector in the third quarter of this year. Douyin, the Chinese sister app to TikTok, has offered such services since 2019. [Reuters]
