Hi HN! I built a simple chess game so that my son in Singapore can play chess with his grandfather in China.

Why? There is currently no service or open source software that has all of the following:

* All processing and assets on a single server (Critical to workaround a firewall) * No email account required (Chinese Internet services typically login via WeChat) * Works on Android browser * Simple to install and config

I built it, together with Claude Code, using simple and boring technologies (Django + Client-side JS). I hope that when you use it, you will find it simple to understand (everything is done server-side), deploy, play, and maybe even hack. :)
