In the Sliding Ball game you will have to help a round ball to survive, which has found itself in a deadly trap. In front of you on the screen you will see the rail on which your character will be. It will move left and right at a certain speed. White squares will start falling on top of the ball. You will have to do so that none of them touches your hero. This is pretty easy to do. You will need to click on the screen with your mouse. Thus, you will change the direction of movement of your ball, and it will dodge the falling squares.
