Localizing a Web Game for China (2026)
Localizing a web game for China is not translation. Translation is the easy 10%. The hard 90% is that the technical and legal environment is different: your fonts, your host, your payment provider, and half the third-party services you quietly depend on all change or break at the border. This guide is the checklist of what actually has to happen.
If your target is Mini Games specifically, pair this with the WeChat and Douyin publishing guide. This page covers the broader web-game case, whether you're going to a Mini Game platform or a standalone site.
Language: Simplified Chinese, done properly
Start with Simplified Chinese (简体中文), the written standard in mainland China. Traditional Chinese is for Hong Kong and Taiwan and is not interchangeable. Get the variant right before anything else.
Then handle the parts machine translation won't. Chinese text is denser than English, so UI that was tuned for English strings will have awkward whitespace, and buttons sized to "Continue" look strange holding two characters. Line breaking works differently because there are no spaces between words. And tone matters: a literal translation reads as robotic to Chinese players in exactly the way a literal Chinese-to-English translation reads as robotic to you. Budget for a native pass, not just a model output.
Fonts: the trap nobody expects
This is where most Western web games fall over. You cannot pull Chinese fonts from Google Fonts, because Google is blocked in mainland China and the request simply fails. A page that renders beautifully on your machine shows broken or fallback text inside the Firewall.
Worse, Chinese fonts are huge. A full CJK typeface covers tens of thousands of glyphs and can run into the tens of megabytes, which is a non-starter for a web game and outright impossible under the Mini Game package limits. The fixes: lean on the system fonts each device already has, or subset a font down to only the characters your game actually uses and self-host that. Either way, host the font yourself from inside China. Don't rely on an external font CDN.
Hosting: inside the wall or slow outside it
Where your game is served decides how it feels. Host offshore and every request crawls through the Great Firewall's inspection, adding latency that makes a real-time game feel broken. Host inside mainland China and it's fast, but hosting in China means the ICP filing.
The ICP (Internet Content Provider) filing is a registration with China's Ministry of Industry and Information Technology, mandatory for any site served from mainland servers. It comes in two forms: a basic filing (备案) for non-commercial sites, and a commercial ICP license for sites that sell, advertise, or take payment, which a monetized game does. A game operating commercially also generally needs an Internet Culture Business License (网络文化经营许可证). The ICP number has to appear in the site footer, linked to the government records site. Filings take weeks and require a local business entity, which is one more reason foreign studios work through a Chinese partner.
The filing isn't just red tape. It's the key that unlocks the rest: onshore hosting, a Chinese CDN for fast delivery across the country, and payment integration.
Payments: WeChat Pay and Alipay, not Stripe
Chinese players don't use the cards and wallets the rest of the world does. Payments run through WeChat Pay and Alipay, full stop. Stripe, PayPal, and Western card flows are not the answer. Integrating WeChat Pay or Alipay requires onshore hosting and the ICP license, so payment, hosting, and filing are one connected problem, not three separate ones. Plan them together.
The services that silently break
The most painful bugs in a China launch are the ones that don't show up until a player inside the Firewall loads the game. Anything your game fetches from a blocked service fails, often silently, even after your hosting and filing are correct. The usual casualties:
Google Fonts, Google Analytics, and anything else on Google. Blocked. Replace with self-hosted fonts and a domestic analytics provider.
YouTube and embedded video from Western hosts. Blocked. Use a domestic video host if you embed trailers.
Facebook, Twitter, and their SDKs and share buttons. Blocked. Swap in WeChat and Weibo sharing.
External CDNs and script hosts you didn't think about. Some work, many don't. Audit every third-party URL your game loads and assume each one is guilty until proven reachable.
The rule: if a resource is served from a company that's blocked in China, it will fail for your Chinese players regardless of how correct the rest of your setup is. Self-host or find a domestic equivalent for every dependency.
Content review
China reviews game content, and standards differ from Western platforms. Themes, imagery, and text that pass elsewhere can be flagged. This is another place a local publisher earns their cut, since they know the lines and can review before submission instead of after a rejection. Build the review step into your timeline rather than treating it as a formality at the end.
The localization checklist
Translate to Simplified Chinese with a native tone pass, not just machine output.
Fix UI for denser text and different line breaking.
Self-host subset or system fonts. Never load Chinese fonts from a blocked CDN.
Decide hosting: onshore with an ICP filing for speed and payments, or accept offshore slowness.
Integrate WeChat Pay and Alipay for anything monetized.
Audit every third-party resource and replace what's blocked.
Plan for content review with a local partner.
Where Cinevva fits
The honest version: the game is the portable part, and the China layer is distribution and compliance. Cinevva builds web-native games that already run from a link with no install, which is the shape China's platforms want, but we won't pretend the ICP filing, the local publisher, or the payment integration are things a tool makes disappear. What we do make cheap is the part before all that. Build the game, prove it's worth localizing, and only spend on the China stack once you know the game earns it. Most games don't need to survive that checklist. The ones that do are worth doing it properly.
Frequently asked questions
Do I need an ICP license to run a web game in China?
To host inside mainland China, yes. Non-commercial sites need a basic ICP filing (备案); commercial sites that sell, advertise, or take payment need a commercial ICP license, and a monetized game generally also needs an Internet Culture Business License. Hosting offshore avoids the filing but makes the game slow through the Great Firewall.
Why do my fonts break in China?
Almost always because you're loading them from Google Fonts or another blocked CDN, which fails inside the Firewall. Chinese fonts are also very large, so the fix is to subset the font to the glyphs you use and self-host it, or rely on device system fonts.
Can I use Stripe or PayPal for a game in China?
No. Chinese players pay with WeChat Pay and Alipay. Integrating either requires onshore hosting and an ICP license, so payments, hosting, and the filing are one linked project.
What third-party services break in China?
Anything from a company blocked in the country: Google (Fonts, Analytics), YouTube, Facebook and Twitter SDKs, and many external CDNs. Audit every URL your game loads and replace blocked ones with self-hosted assets or domestic providers.
Is translating to Chinese enough to localize a game?
No. Translation is a small part. You also have to handle denser text and line breaking, self-hosted fonts, onshore hosting and filing, local payments, blocked third-party services, and content review. The language is the easy layer.
