TikTok is reportedly testing games for the app in Vietnam ahead of a “big push” into the market, according to Reuters. “We’re always searching for ways to expand our platform and routinely test new features and integrations that provide value to our community,” a business official acknowledged tests of HTML5 mini-games.

According to the outlet’s sources, the goal is for ad-supported games based on the ByteDance library, which may raise income and the amount of time users spend on the TikTok app — if that’s even possible.

TikTok has already tried at least one in-app mini-game, collaborating with Feeding America to create Garden of Good, a FarmVille-style experience in which users could earn points and donate them. Late last year, it announced a deal with Zynga, the creator of FarmVille, to create Disco Loco 3D, an HTML5-based endless runner that may function inside the app, but fresh rumors suggest that’s only the beginning for TikTok’s gaming aspirations.
