Under the hood
How it's built
- Three.js draws the table, paddles and ball, with real-time shadows so you can judge the ball's height. Every shot is planned from the spot where it will bounce, which is how it always clears the net.
- The rules live in their own module and run at a fixed 120 steps a second, apart from the drawing, so the game plays the same on a 60Hz laptop and a 144Hz monitor. I tuned the three CPU levels by simulating thousands of matches against bots of different skill.
- Finished matches go into IndexedDB in your browser, along with your level and sound settings. No account, no server, and clearing your site data wipes it.
