🧠 Inspiration We were inspired by Reddit's chaotic, meme-driven culture and the universal inside joke: "How fast can you get banned from a subreddit?" This project started as a shitpost idea — but turned into a clever way to combine LLMs, Reddit’s API, and Bolt’s fast prototyping tools into something weird, funny, and surprisingly interactive. The spirit of the Useless Sh!t Challenge was the spark — and we ran with it.
🤖 What it does Ban Speedrun is a game where the goal is to break Reddit's rules — as fast as possible.
Users pick a subreddit
We pull the real rules using the Reddit API
An AI agent generates increasingly ridiculous, rule-breaking posts
Players escalate through 5 “offense levels”
The game ends when they reach peak absurdity — and get a shareable “Ban Speedrun Score”
It’s part simulation, part satire, and all chaos.
🛠 How we built it Frontend: Built entirely with Bolt.new, using its UI builder to design screens, offense meters, countdown animations, and more.
Backend Agents: Powered by GPT-4o, our main agent takes subreddit rules and offense level as input and generates meme-worthy Reddit posts designed to break rules in funny ways.
Reddit API: We fetch live subreddit rule sets via Reddit's /about/rules endpoint to make the game reactive and specific.
Gameplay State: We used Bolt’s global state to track offense level, store AI output, and control transitions between UI states (e.g. loading > countdown > game > results).
Humor Engine: The core value comes from the prompt engineering and escalation system — each level is weirder and more ban-worthy.
🧩 Challenges we ran into Parsing Reddit rules: Every subreddit formats rules differently, so we had to design flexible prompts that could adapt.
Tone balancing: We wanted humor and rule-breaking — without promoting actual hate speech or unsafe content.
Visual pacing: We had to make the game feel fast and reactive with minimal animations and frontend tools.
Getting the AI to be just offensive enough without going too far — that took some careful tuning.
🏆 Accomplishments that we're proud of Turned a literal joke idea into a working, interactive AI-powered game in just a few days.
Fully integrated Reddit API + AI + Bolt Agents + UI — all in a compact, viral experience.
Designed a game that feels native to Reddit culture, meme-friendly, and perfect for social sharing.
Prompt engineered an LLM system that escalates chaos in a funny, controlled way.
📚 What we learned How to work with Reddit’s API in unexpected ways (turning rules into gameplay).
How to guide LLMs to produce humor that walks the line between edgy and ethical.
How to use Bolt’s state system and agents to coordinate multi-step, visual game logic.
That even silly, “useless” ideas can have surprising technical depth and storytelling power.
