Some kids had every resource imaginable; others had never touched a computer. I wanted to build something free, browser-based, and unique that anyone could use to learn how to code without needing an account, a subscription, or a powerful computer.</p> <p>Claude Code helped me build it. I handled the design direction and content. Claude wrote most of the implementation.</p> <p><strong>What is it</strong></p> <p>Forge Code is a coding challenge game that runs entirely in your browser. You write a solve(text) function, hit run, and it checks your answer against the expected output. JavaScript runs natively in a Web Worker. Python loads via Pyodide. Nothing is sent to a server. No login required.</p> <p><strong>Two tracks</strong></p> <p>The site is split into two completely separate paths.</p> <p>The Academy is for beginners. There are 24 challenges, and every single one is preceded by a lesson. It is designed for people who have never written a line of code.</p> <p>The Gauntlet is for people who want a real fight. It is a story campaign across five acts, starting at medium difficulty and escalating to genuinely brutal algorithmic puzzles. Every hard challenge generates a unique input per player using a seeded RNG, so your numbers are different from everyone else's. You cannot just copy someone's answer.<br> **<br> How the puzzle system works**</p> <p>This was the part I was most excited to build. For harder challenges, instead of everyone getting the same input, the system seeds a random number generator with your player ID and the challenge ID. That seed deterministically generates your puzzle input and the correct answer.</p> <p>If you try it, I would genuinely love feedback such as which challenges felt too easy or too hard, and whether the Academy lessons actually taught you anything. Have fun coding!</p> <p><a href="https://forgecode.org" rel="noopener noreferrer"></a></p> <p><a href="https://forgecode.org" rel="noopener noreferrer">https://forgecode.org</a></p> ai webdev javascript tutorial
