Move the paddle using arrow keys to keep the ball in play. Score 1 for each brick in level 1, 2 in level 2, 3 in level 3, 4 in level 4. Max Score = 500 including 100 bonus for no lives lost. You must move the paddle to under the ball BEFORE the ball arrives otherwise the ball continues slowly past the bat. The ball will rebound evenly if hit with the middle of the paddle but will rebound with spin if hit near the leading or trailing end of the paddle. Try it. The ball moves faster at higher levels. There are 4 levels. The ball can rebound off any of the four sides of a brick. Each serve will be at an angle of -45 or 45 degrees. There is a 2 second delay before each serve.
