Governments are weighing legal caps on children's playtime
Only China and Vietnam cap children's playtime by law, checking every player's identity to enforce it. Elsewhere the idea has become advice or parental tools. The US and EU are now drafting rules, so whether caps work now matters, and the evidence is split.
Where it stands
China allows under-18s three hours of online games a week, and Vietnam three hours a day across one company's games. South Korea repealed its midnight curfew in 2021. In 2026 the US House passed a bill requiring a parental timer, and the European Commission proposed time-management tools, but neither sets an hour limit or is law. On whether caps work, the largest study found no drop in heavy play after China's first rule but could not separate children from adults, while a later survey found children playing less.
| Market | The rule | What it says | Source |
|---|---|---|---|
| China | Three hours a week, enforced by ID | Under-18s may play online games only from 8pm to 9pm on Fridays, Saturdays, Sundays and public holidays. Every player must log in under their real name, which the publisher checks against state records. | National Press and Publication Administration (30 August 2021) |
| Vietnam | An hour per game, three hours a day | Since 25 December 2024, under-18s are limited to 60 minutes on any one game and 180 minutes a day across all the games of one company. A draft published in July 2026 would cut under-16s to 60 minutes a day in total. | |
| South Korea | Curfew repealed | South Korea blocked under-16s from online games between midnight and 6am from 2011. The National Assembly voted to scrap the law in November 2021. A voluntary system remains, in which a parent or the child can ask a publisher to block chosen hours. | |
| USA | No cap: a bill would require a parental timer | A bill the House passed in June 2026 would make game companies give parents a tool to limit play time for users they know are under 17. It sets no limit itself, and it is not law: the Senate has not taken it up. | |
| Japan | One prefecture, advisory only | Kagawa prefecture's 2020 ordinance advises under-18s to play no more than 60 minutes a day on weekdays and 90 on weekends. It carries no penalty, and a court upheld it in 2022. | |
| India | No cap | The government said in 2022 that it was not considering limits on play time. The online gaming rules that took effect in May 2026 ban games played for money and require age checks and parental controls, but do not limit recreational play. | |
| EU | Proposed: time-management tools | The European Commission announced a proposed law on 17 September 2026 that covers online games. It would require effective tools for managing time, to protect school time and children's core sleep hours. It is a proposal, not yet law. | European Commission, The KIDS Act explained (17 September 2026) |
| Brazil | No cap: parental time limits required | Since 17 March 2026, games and other online services that children are likely to use must give parents tools to limit and monitor time of use, with default settings at the highest level of protection. The law sets no limit on play itself. |
Timeline
2011
South Korea bars under-16s from online games after midnight
South Korea's shutdown law takes effect in November 2011. It blocks under-16s from online games on computers between midnight and 6am.
2017
Tencent caps children's play on its biggest game before any law requires it
Tencent limits under-12s to one hour a day and 13 to 17 year olds to two hours on Honor of Kings, its most popular mobile game, after reports of children spending thousands of dollars in it.
2019
China sets its first national limit on children's play
China's games regulator requires every player to register under their real name. Under-18s get 90 minutes a day, three hours on holidays, and no play between 10pm and 8am. It also caps what children can spend.
2021
China cuts the limit to three hours a week
From 1 September 2021, under-18s may play online games only from 8pm to 9pm on Fridays, weekends and public holidays.
National Press and Publication Administration (30 August 2021)
South Korea votes to scrap its curfew
South Korea's National Assembly votes to abolish the shutdown law. The Korea Herald's editorial says there was little if any scientific evidence that it worked.
2023
The largest study of China's first cap finds no drop in heavy play
Researchers analyze 7 billion hours of play recorded by game software in China. The share of weeks with heavy play was 0.77% before the 2019 rule and 0.88% after. The data carried no ages, so the study could not separate children from adults, and it covered the 2019 rule, not the stricter one of 2021.
2024
Vietnam's limits take effect
Decree 147 takes effect on 25 December 2024. Under-18s are limited to 60 minutes on any one game and 180 minutes a day across one company's games, with accounts tied to a phone number or identity number.
2025
China's games industry says seven in ten children play under three hours a week
The industry association's yearly survey reports that 71.0% of minors play less than three hours a week. Of the children who went over the limit, 73.4% did it by using a parent's or older relative's account or identity.

2026
The US House passes a bill with a parental timer for games
The House passes the KIDS Act by 267 votes to 117. Its games section would make companies offer parents a tool to limit play time, and switch chat protections on by default for children. TechPolicy.Press calls its prospects in the Senate dim.
Vietnam proposes cutting under-16s to an hour a day
Vietnam's broadcasting authority publishes a draft that would limit under-16s to 60 minutes of games a day in total, down from 180.
The European Commission proposes time tools for games
The Commission announces a proposed law on children's safety online that covers online games and game platforms. It asks for age checks and for tools that protect school time and sleep. It does not set a limit on hours.

Consequences
012021
The cap costs the big companies little today
The new rule cut a child's weekly allowance from 13.5 hours to 3. Niko Partners points out that children were already a sliver of the business: Tencent had said only 2.6% of its revenue came from players under 16. The risk it sees is longer term, in a generation that never forms the habit, and in esports, which needs young talent.
022022
The limits work as consumer protection
The legal scholar Leon Y. Xiao argues the rules should not be dismissed as draconian. Tencent reported that minors' share of spending in its games fell from 4.8% to 1.1% in a year, which means far fewer children buying loot boxes, the paid random prizes in games. The penalties fall on companies, not on children.
032025
Children play on their parents' identities
The Chinese industry's own survey shows where a cap enforced by ID leaks. Most children who broke the limit used an adult relative's account, and 44.84% of parents surveyed had registered a game account for their child under their own identity.

042021
A curfew breaks things it was never aimed at
The Korea Herald's editorial lists what the shutdown law got wrong. Microsoft made Minecraft adults-only in South Korea rather than build a curfew system for one country. The law missed mobile games entirely. And children were losing sleep to cram schools, not to games.
Objections
Counterpoint2025
The two main studies disagree, and neither settles it
A 2025 study of 2,715 Chinese adolescents found 93.6% complying with the 2021 rule. Average daily play fell from 60 minutes to 44, and among the heaviest players from 211 minutes to 132. It relies on what the adolescents said about themselves. The 2023 study used recorded play but had no ages, so its authors say they cannot rule out that children played less while adults played more. The two have not been reconciled.
Zhou and colleagues, Journal of Behavioral Addictions (15 September 2025)
Counterpoint2024
The heavy players in the surveys were already breaking the earlier rule
Leon Xiao points out that a cap of 90 minutes a day had applied since 2019. The heavy players in the 2025 study were all playing at least two hours a day before the 2021 rule, so they were already breaking the old one. High compliance in a survey says little about children who are determined to get round the limit.
Leon Y. Xiao, Journal of Behavioral Addictions (4 November 2024)
Counterpoint2025
The only yearly figures come from the industry itself
No independent body publishes how much Chinese children play each year. The yearly figures come from the games industry's own association, from a questionnaire of about 5,000 people. It reported 24.9% of minors playing three hours a week or more in 2024, and 71.0% playing less than that in 2025.
China.com, on the games industry association's 2025 report (22 December 2025)
What to watch
2026
China's next yearly report on minors
Mid to late December 2026, when the Chinese industry association usually publishes its yearly report on protecting minors. The figure to look for is the share playing under three hours a week. It was 71.0% in 2025. The 2024 report gave 24.9% playing three hours or more, which implies about 75% playing less, so on the association's own figures the share keeping to the limit slipped. The two surveys may not be comparable.

2027
Whether the US bill survives
Early January 2027, when the current US Congress ends. The Senate has advanced a different children's safety bill, without the games section. If the House bill does not pass the Senate by then, it lapses.
