Pong: you vs the model
Classic Pong against a paddle with no script. Many times a second it reads what moving up, staying or moving down would lead to, and picks one, live in your browser. Or let it play both sides.
Try this: Press Start and move your paddle with the mouse, a finger or the arrow keys. Hit the ball off the edge of your paddle for a steep angle and watch its bars scramble.
The model's paddle weighed
Its options show up here once the ball is moving.
The game does the physics: it projects the ball, wall bounces included, from the moment the next answer will land and writes down what each move leads to. The model reads those sentences and picks. Nothing overrides it, so when it picks wrong, it misses. In self-play the two paddles take turns asking, which halves how often each one gets to think. At a higher speed the ball covers more ground while an answer is on its way.
