Press the green flag and press the blue button that says, "click here to play" Move your mouse to move the paddle and don't let the ball touch the red line. If you press the green button but it brings you back to the front page, go back and click it again. Note, ball moves slow because it moves too fast when set to 9 steps due to a bug or something and in level 2 the ball may move very fast and if that happens, let it touch the red line and try again. There is no winning score so just play as long as you want until you lose.
