Anyone who had an Atari in the '80's knows what this is. It's a classic. Use your paddle to bounce the ball into the brick wall. Each time you hit a brick it disappears. Once you break through, the ball will bounce around the top knocking out blocks rapidly. Try to get rid of all of the bricks on the screen. It's harder than it sounds.
Each time you hit a brick with the ball, you score the appropriate number of points and the brick disappears, if you strike multiple blocks in quick succession points are multiplied.
