This is a tough question, I know. But you can easily answer it by playing this simple, addictive game: it only takes a couple of balls and a lot of mouse dexterity!
Balls puts you in control of a small gray ball that you must place over a hollow ball to make it disappear. To make things harder, there’s another black ball which will chase you all over the area, making you grow if it touches you. This growth in turn makes it more difficult to avoid the black ball, and if that wasn’t bad enough, the walls surrounding the game are continuously closing in on you.
That said, the only thing you can do is move as quickly as possible and try to do your best to show off your balls in the worldwide online top scores list.
