```markdown Hi Product Hunt 👋 — I'm the maker of YiBoard. This project started with a simple observation: Western board games are everywhere online, but the Chinese classics — Gomoku, Xiangqi, Go — rarely get the same treatment. And when they do, they're usually behind a signup wall or buried in a mobile app you have to install. So I built the opposite: a browser tab, a board, and nothing else. No install, no account, no waiting in a queue. Open it, play a match, close it. Your rating (real Grades and Dans, not platinum badges) stays if you choose to attach an email. Three things I'm proudest of: 1. **Server-side refereeing** — every move in an online match is validated by the server before it lands, so a modified client can't fake a win. 2. **A real engine in your browser** — alpha-beta pruning under a hard 500ms budget, running locally. No server round-trip, which means no rate limits and no queue even when we're busy. 3. **Four languages done properly** — English, Español, 日本語 and Português do Brasil, including rules and error messages, not just the marketing page. Right now Gomoku is fully playable; Xiangqi is in development and Go is planned. Happy to answer anything about the ranking system, the engine, or the roadmap. Would love to hear what you'd want first — Xiangqi or Go? 🎯 ```
