When balls of the same color collide with each other, they disappear. Hold your left mouse button down until the desired power and angle is determined. Let go of the left button to take the shot. Your first shot must be with the white ball after which you can move any ball. Collect the tiny dots for more points by colliding with them. When a bigger ball and a dot of the same color collide, you get more bonus points than if a ball of a different color collides with it. You will also need to clear these to complete a table.
