The Wheel Reinvention Jam is a one-week jam where we build software from scratch.
Why build things from scratch? Because that's the only way real progress is made. Every impactful project started life as a small experiment. Plus, writing something from scratch turns theory into practice. You may think you know how a piece of technology works, but until you write it yourself, it won't really stick. There's no substitute for direct experience.
And let's face it, most of the software we use is basically the same as it was twenty or thirty years ago. Our "wheels" are terrible! They need to be reinvented!
So take this opportunity to try something ambitious, something weird, an unfamiliar take on a familiar problem. Who's gonna stop you?

We owe the name “Wheel Reinvention Jam”, and its logo, to Casey Muratori. At the start of Handmade Hero, literally in episode 1, a viewer asked the question: “Why not use an engine? Why reinvent the wheel?”
Casey’s answer deserves to be watched in its entirety, but part of it is shockingly relevant right now:
If you start with an engine, then it changes what you’re learning from the fundamental truth of how to implement a game to someone else’s version of that. […] What you’re really learning is that engine. You haven’t learned how to make games, you’ve learned how to make games in Unity. Right? And if Unity were to disappear, for example, you would no longer know how to make a game at all. I’m not exaggerating this, that’s just the truth.
We could not have planned this jam at a more opportune time. Unity recently announced a dramatic change to their pricing structure that leaves the future of many game studios in doubt.
What Casey said back in 2014, at the very inception of the Handmade community, has now come to pass. For many game developers, Unity is no longer an option. And just like Casey said, their very existence in the industry has now come into question. Will they be able to make games at all?
Casey’s reasoning holds as true today as it did then. The world needs engine programmers! Programmers who understand how engines work aren’t constrained by the limitations of the engine - they know what’s fundamentally possible and can work around constraints to achieve anything they want. But more than that, our current engines are not good enough! We need people making new engines, better tools, better wheels.
This is not just true for game engines. It’s true of the entire software industry. We need new video editors, new platform layers, new code editors, new databases, new networking protocols, new compilers, new typesetting systems, new presentation programs, new graphics APIs, new operating systems.
We will never make progress unless we reinvent the wheel.
The jam takes place from Monday, September 25 through Sunday, October 1. Here's how you can participate:
Create a Handmade Network project to track your work. Then, build your program! Share your work in progress in #project-showcase on Discord, or directly from your project page. Posts on Discord can be tagged so they automatically appear here on the website.
Your Handmade Network project is your submission. Fill out the project description, making sure to explain the goals of the project and why you chose to build it. Also consider posting an update with video of your program in action!
Submissions are now closed.
There are no explicit winners, but we will be selecting a few of our favorite projects to highlight in a recap stream following the jam.
Your Handmade Network project is your submission. We will be looking at the project's description and any extra updates you share toward the end of the jam.
