Show HN: Daily vibe-coding video games, day 87: Jungle Chess

Post by pzxc » Thu, Jul 09, 2026, 4:59 PM UTC

87 days of making a new video game with Cursor and Claude AI, online free to play with no download required and high scores enabled. HTML5/Canvas/Websockets. Happy to answer questions! I can't believe I'm still going with this after almost 3 months, but I'm still having fun!

Today's game is a Chinese version of chess called "Jungle" or "Dou Shou Qi", it's basically chess with animals. The larger animals capture the smaller animals, with the exception of the Rat (smallest animal) which can swim in the water and capture the elephant (largest animal).

If you're curious, this is the single prompt used to build the game with Claude Sonnet 5.0 on Medium:

> Create game 197 "Jungle" based on the Chinese board game "dou shou qi". Since it's a board game it can use a regular controller (doesn't need websockets), but please include scoring (backend authoritative/anticheat) and sound effects (ui/lib/sfx.ts)

I did later have a second prompt but it was just to renumber the game to make it ready for publishing, after playtesting and finding no issues. And of course a lot of the infrastructure (including the sound effects library) was built in previous sessions.

If you have any questions, lay 'em on me!
