3D games. The shape is the lesson.

Each game teaches one idea about how AI works, and it's only 3D when seeing it in space is the point. Free in your browser on a phone or a Chromebook. No login, and nothing you do in a game leaves your device.

  Loss Mountain

  Walk the robot downhill in the fog. That's how AI learns.

  A 3D hill where height is how wrong a model is, and the robot can only feel the slope under its feet. Pick a step size and walk it down: too small and you run out of steps, too big and you fly off. 5 hills, from a simple bowl to a real one built from Weight Pond's pond 3. Walking downhill like this is how AI learns.

  GPU Paint Race

  One fast painter or 64 slow ones? Race them and see why AI runs on GPUs.

  Two 3D walls of pixels and two crews: one fast CPU painter, or 64 slower GPU painters who all do the same step at once. Pick who finishes first, then watch them race. 5 jobs, from painting a wall to following a trail where extra painters can't help, ending with a real neuron on a million dots. It's why AI runs on GPUs.
