Singularity News CCG – A No‑Build, AI‑Powered Card Game

Description and use

A no‑build, AI‑generated card game that runs as a PWA and includes an auto‑play feature.

Create an interactive, AI‑generated card game that can be played offline on mobile and desktop without a build step.

The project delivers a playable, AI‑generated card game that runs offline, can be installed on mobile, and requires no build step.

1. Design card game concept and rules.
2. Use Gemma 4 via Gemini API to generate news ticker, character interviews, intro narration, and epilogue article.
3. Use gpt‑oss‑120b on Groq as a fallback AI model.
4. Implement game logic in pure HTML/CSS with 3D rendering from previous Flogons project.
5. Add Auto:on feature to auto‑play the game.
6. Deploy as a PWA on Vercel.
7. Provide demo via CodePen and GitHub repo.

The CSS-based 3D rendering introduced there came in extremely handy, along with the pure HTML concept, resulting in a no-build development approach.

Gemma – Gemma 4 (gemma-4-26b-a4b-it, via the Gemini API) and gpt-oss-120b (on Groq) was used.

The whole build process is documented in PROMPTS.md – every prompt I gave the agent, in the original Hungarian.
