Marvel Snap” is a casualty of the U.S. government’s move to ban TikTok over fears about its Chinese parent company. It’s not just TikTok that winked offline for U.S. users Saturday, just hours before the Jan.

Marvel Snap,” a popular mobile card game published by ByteDance’s Nuverse games division, shut down gameplay over the weekend as the U.S. TikTok ban took effect.

The divest-or-ban law aimed at TikTok is also taking down other ByteDance-linked apps, including the popular card game Marvel Snap. The app suddenly cut off access Saturday night, seemingly without warning, surprising gamers who weren’t aware of its connection to ByteDance.
