Press the green flag. If "You win" or the letter "A" or a orange button comes up at the start, press green flag again. Make sure you press the button, not the word "start". If your score is 10 and the ball and paddle hasn't gotten smaller, press the green flag again. Press start to start the game. Move mouse to control paddle. Don't let the ball touch the red line. When your score reaches 10, 20, 30 and 40, the ball and paddle will get smaller. Once your score is 50, YOU WIN! Enjoy!!!
