4399 (小游戏) : China's long-running site for free mini-games that play instantly in your browser.

4399 launched in 2004 as a Chinese portal for free games played straight in a browser. Run by 4399 Network of Xiamen, it reports cumulative registered users above 600 million.

Games start instantly with no download, from quick puzzles to competitive picks built for short play sessions.

Its audience skews toward school-age kids and office workers across China. The site and its games are in Chinese, so overseas visitors need basic reading ability to navigate.

Is 4399 still relevant in the mobile era?

4399 has declined as Flash was deprecated and mobile gaming overtook browser games. However, it still receives significant traffic from Chinese schools and public computers where installing games is restricted.

Does 4399 contain malware or ads?

4399 is a legitimate established site, but it uses aggressive advertising including pop-ups and video ads. Some third-party ad networks have served misleading download buttons. Using an ad blocker is recommended.

Can I access 4399 from the US?

4399.com is accessible from the US, but the site is entirely in Chinese. It hosts thousands of browser-based Flash and HTML5 casual games. Registration is not required to play most games.
