Play it: how do simple rules build a world nobody designed?

Set the rule, seed a pattern, watch what emerges, and notice the only thing you actually chose was the rule. That's AI, too: a few people pick the rules, and the rest of us inherit the world those rules grow. New to this idea? read how the game works ↗

It starts running on its own the moment you reach it. Draw your own cells, drop a classic, or change the algorithm, and watch everything change with it.

Drop a pattern

Click & drag on the grid to draw your own cells. Space play/pause · S step · C clear. The grid wraps at the edges, like a torus.

Here's the catch, and it's the whole point: in Conway's world you can see the rule. Three numbers, right there. In a real AI model, you can't. That's exactly what makes "who sets the rules" the hardest question in the field, and harder than this toy makes it look. It's the question I work on.
