Balls is a very easy skill game?the rule is simple, and you just need to control the white ball and keep it stay on top of the blue box. However, it is not easy for you to get a high score?those annoying grey balls will knock the white globe about. So sometimes you need to avoid their trying to drive the white sphere out, while sometimes you need to utilize their knock so that you can stay on the box. So you must love this ?simple? game. Good luck!
