Make a game. Mod it. Ship it.
Build a pixel game, tweak its rules like a modder, add a DLC world and publish it with a link. Then spin 3D models and watch an algorithm think. No sign-up.
Start forgingPixel Forge
A tiny runner. Tap, click or press Space to jump: collect stars, dodge spikes. Then open Mod and DLC and make it yours.
How it's built
The whole game is about 200 lines of code: a loop that moves the world, a few numbers (gravity, speed, jump) and pixel sprites drawn square by square. The Mod tab lets you change those numbers live.
Mod the rules
A mod changes the rules or the look of a game that already exists. Modders don't rewrite the game, they change its variables. Every slider here is a variable in the code.
Add a world
DLC (downloadable content) adds new worlds, items or levels on top of a finished game. The base game stays the same; the DLC stacks on it. Gems only exist in DLC worlds.
Publish your version
Publishing packs your mod values and your DLC into a link. Anyone who opens it plays exactly your game. No account, no upload: the settings travel inside the link.
3D Lab
Drag to spin. On the platform, study kits come with 3D models you can turn, take apart and quiz yourself on.
Pathfinder: watch an algorithm think
Draw walls, then press Run. The robot doesn't see the maze: it follows a rule, step by step. That rule is the algorithm.
All 5 badges. You're a maker.
On the platform this is the real thing: an AI helps you write the code, and every game, mod and world goes live on your own page. Show this to your parents.
