FixAI: Browser Game Teaches Consumer Law by Fighting Corporate AI Bots

What This Is

FixAI is a browser game where players fight corporate and government AI bots that have wrongly denied consumer requests. The game uses real consumer laws as weapons, with each level representing a different denial scenario.

Game Mechanics and Features

The game includes 36 levels covering various denial scenarios: flight refunds, visa applications, medical authorizations, and gig worker deactivations. Players argue back using real laws, and the AI's confidence (represented as resistance) drops as correct arguments are found.

New this week: After every win, a "What you just used" panel appears showing the law cited, what it actually means, and how to use it in a real dispute. This was a one-day build that significantly changed the game's feel.

Technical Stack and Implementation

The game is built with Vanilla JS and Node/Express, using Claude Haiku as the AI engine. Each bot has a system prompt with a resistance scoring system - Claude returns {message, resistance, outcome} JSON on every turn, and the game reads it directly.

Prompt Design Challenges and Solutions

The interesting technical aspect is the prompt design. Each bot has:

• A distinct personality
• Starting resistance between 60-95
• Specific legal arguments that reduce resistance by defined amounts

The main challenge was Claude breaking character on sensitive scenarios (medical denials, disability cases) to announce it's made by Anthropic. This was fixed by framing the entire game as an educational simulator in the system prompt.

The game is available at fixai.dev and is free to play. The developer is seeking honest feedback from the community.
