Popular quiz game Brain King disappears from WeChat
Netizens speculate sensitive questions may be to blame

It’s a stunning turnaround for a game that was quickly gaining mass popularity. Brain King was a mini program within WeChat, meaning it was playable from inside China’s ubiquitous app. Playing with your WeChat contacts or pitted against a stranger, whoever answered a series of questions fastest won.
It could be the source of those questions that are to blame for the game's removal -- many of them come from users. Chinese netizens are pointing to questions related to former president Jiang Zemin as the reason for Brain King’s troubles, but it's still unclear exactly what triggered its downfall.

Users have complained about Brain King’s crowdsourced questions before -- not for controversial content, but because they are tired of seeing absurd questions, or ones which are impossible to answer correctly.
Examples of the more ridiculous questions reviewers posted online include:
Q: Are you dead?
