AI Validation Game
Learn how to catch AI hallucinations before they ship.
This browser-based developer education game teaches prompt validation and AI output review through five practical districts that mirror real engineering work.
Built for Real Developer Work
Each district mirrors practical engineering workflows where confident but wrong AI output can create production mistakes.
Free Browser Game
Play instantly in the browser with no signup, no backend dependency, and local-only progress saved on the device.
District Grid
Five systems. Five failure modes.
The map is ordered as a guided campaign, but once unlocked each district can be replayed to sharpen a specific AI validation skill.

District brief
A junior engineer needs API docs for a `resetSession` endpoint. The AI answer looks polished but does not define the request format or failure cases.
Validation focus
Ask for structure, examples, and output constraints.
Why this district is dangerous
The team can implement the endpoint incorrectly because required fields, error states, and contract details are missing.
Verification checklist
- Request method, route, auth assumptions, and body fields.
- Demand one success example and at least one failure example.
- Check whether edge cases and response schema are explicit.
The `resetSession` endpoint resets the user session and should be used when needed. It returns a success response and improves security. Developers can call it after login issues. It is straightforward to integrate and recommended for all clients.
Campaign progress
Choose your validation move
Do not fix the answer with instinct alone. Select the move that forces the model back into evidence, constraints, or concrete verification.
Recovered Skills
What the city taught you
Progress is local, but the habits are portable: stronger prompts, sharper validation, fewer expensive mistakes.
Docs District
A useful AI answer is specific, testable, and structured.
Debug Alley
Evidence outranks confidence.
SQL Docks
Correct SQL starts with correct assumptions.

What is Escape From Hallucination City?
Escape From Hallucination City is a browser-based educational game that teaches developers how to validate AI output before trusting it in real workflows.
What does the game teach?
The game teaches prompt validation, AI hallucination detection, debugging verification, SQL review, regex testing, and more specific commit writing habits.
Who is this AI validation game for?
It is designed for developers, engineering teams, students, and anyone who wants to use AI tools more critically instead of accepting confident answers at face value.
Does the game require a login or backend?
No. The MVP is static-first, runs fully in the browser, and stores progress only in localStorage.
Is Escape From Hallucination City free to play?
