WeChat Mini Games for Western Developers: Terms, Publishers and the Port

01

What a mini game is, and why it matters

WeChat and Douyin host games that run inside the app, open from a link or a share and need no install. For players they are instant and free; for developers they sit outside the phone-maker Android stores and their 50% cut, and inside a platform that sells the traffic to reach players. The genres that work are the casual and mid-casual ones that work everywhere: match, merge, idle, puzzle and light simulation, played in short sessions.

Trade press; the format is crowded

For a Western studio with a casual mobile game, a mini game is one of three ways into China, alongside the Chinese Android stores and iOS, and is usually the fastest to a live product because the publisher handles the port and the licence. The routes are compared in the publishing guide; the service is on the mobile publishing page.

02

The published terms

The Tencent programme is the clearest published publisher-style deal: Tencent funds the acquisition and the developer keeps a sixth of raw ad revenue. It is a useful floor when a publisher’s offer arrives, because a publisher that funds acquisition is offering a version of the same trade.

03

How a Western studio gets in

Developer access to WeChat and Douyin publishing, payments and the licence needs a mainland entity, so a Western studio works through a Chinese publisher. The publisher rebuilds the game for the platform, integrates the Chinese SDKs (payment, analytics and anti-addiction compliance), files for the licence in its own name, funds the user acquisition and pays a share. The shape our mobile page describes is a 50% share of ad revenue to the developer on agreed reporting cycles, with no upfront cost; casual deals are reported as an advance plus a share, and licence fees are rare.

The publisher needs your source code to do the port, which is standard across Chinese mobile publishing rather than specific to any one deal, so the contract has to say exactly what the build may be used for, with IP reversion and data-handling obligations written in. See how to choose a China publishing partner.

04

The port: what the platform demands of the build

A WeChat port is a technical job first. The constraints are published and they shape which games are feasible.

• Main package of 4MB, 20MB total, 30MB with payments; assets beyond that load from your own CDN.
• Unity projects are converted to WebAssembly through WeChat’s tooling; Cocos and Laya export natively.
• About ten seconds of load is tolerated before players leave; first-session asset streaming is where most ports fail.
• Chinese SDKs for login, payment, ads and the anti-addiction real-name system, integrated by the publisher.
• Share and group mechanics (invite links, group rankings) are the free distribution channel; a game without them pays for every player.

A guide to the technical side from a vendor’s perspective is AppInChina’s WeChat mini-games guide. The publisher does the work; your job is to confirm the game can be rebuilt within the limits before you sign.

05

The licence

A mini game released commercially in China goes through the same approval process as any domestic game, filed by a licensed Chinese publisher. Only a mainland publishing unit can file, and imports are a small slice of approvals: 95 in 2025 and 46 in the first nine months of 2026. Vendor timing estimates for mini-game licences conflict (four to five months in one, six to eight in another, both from companies that sell the service), so quote neither as fact; ask the publisher what it has filed and when it was approved, and check the NPPA’s monthly lists. The full process is in the licence guide.

06

The retention bar

Publishers have moved from judging on day-one payback to judging on depth. First-day return targets reported by one publisher fell from 80% to 90% for hyper-casual to 30% to 60% for medium casual, and 2% to 10% for purchase-led games. Douyin’s own benchmark for a top-tier ad-monetised match game is 19% next-day retention for new users and 53 minutes of play per user, with 15% and 42 minutes counting as acceptable.

1. 1

   Send the numbers you have

   A publisher that funds acquisition is making a bet on retention; the data you already have from the App Store and Google Play is the pitch. Retention and session data you choose to share is what our free assessment reads for mobile games.

2. 2

   Check the genre is not flooded

   Match-3 mini games arrive at over 350 a month. Merge is growing fast and Chinese studios now out-earn Western merge studios in the West. A distinctive mechanic or theme is worth more than polish in a crowded format.

3. 3

   Expect clones

   Clones follow any hit within weeks, and one publisher’s flagship was built from a Steam game’s prototype with no licence mentioned. Speed to market with a partner who can buy traffic is the defence; a contract is not.

07

Where mini games fit against the other mobile routes

The phone-maker Android stores (Huawei, Xiaomi, OPPO, vivo) take 50% of gross billings, and the giants are leaving them: Tencent pulled Dungeon and Fighter: Origin from them in 2024 and NetEase pulled games from OPPO, vivo and Xiaomi in November 2025, pushing players to official downloads and TapTap. TapTap takes no revenue share and lives on advertising, with about 45 million monthly users on XD Inc’s 2025 results. A mini game sidesteps the store cut entirely and trades it for the platform’s ad economy. For a casual game with strong retention and light assets, that is usually the better trade; for a mid-core game with a large build, the stores and TapTap are the route. The cost guide sets out the order of deductions on each.
