In China, gamers under 18 will be banned from playing online between 22:00 and 08:00. They will also be restricted to 90 minutes of gaming on weekdays and three hours on weekends and holidays.
This step is the latest in China's recent move to curb video game addiction, which officials say is damaging to children's health, reports the BBC.
China is one of the world's largest gaming markets.
The government released guidelines, stating total time allowed for gaming, and spending limits. Gamers 8 to 16 years old can spend up to 200 yuan (£22, $29) per month, while those between 16 and 18 years can spend up to 400 yuan on their gaming accounts.
