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.

Stack: Next.js 14, Groq, Supabase, Upstash Redis, Vercel

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