I built a prompt engineering game — here's why I think learning by doing beats every tutorial

Every guide on prompt engineering teaches you theory. Read this, memorize that, here are 10 tips.

The problem? You never actually write prompts.

So I built a game: 10 challenges, each one forces you to use a specific technique — zero-shot, few-shot, chain of thought, role prompting, constraints, and more.

You write a prompt → real LLM responds → second LLM evaluates whether you used the right technique. Not just whether the output looks okay — whether your prompt caused it correctly.

What technique do you think is hardest to learn hands-on?
