How to play
- Start the ball and keep the paddle beneath it.
- Move the paddle to change where the ball rebounds.
- Clear the bricks without letting the ball pass the bottom edge.
What this game practices
Good for informal experimentation with angle and trajectory. It does not display measurements, so the geometry remains intuitive rather than explicit.
