Tencent’s widely popular mobile game Honor of Kings on Tuesday announced rigid restrictions on underage players. Starting from Tuesday, minors under the age of 18 are only allowed to play the game on Friday, Saturday, and Sunday from 8 p.m. to 9 p.m. Tencent made the move after Chinese regulators asked companies to implement anti-addiction measures to protect the country’s youth. CrossFire, a hit first-person shooter game developed by South Korean gaming company Smilegate and represented by Tencent in China, also released similar restrictions on Wednesday.
