Shades of Grey

This is an abstract game. The task is to clean the screen of the circles and not to lose your lives. One circle must destroy the others by means of force of friction. To play this game you need to send the first circle to the playing field very carefully and then send another one so as it could hit the first one to clean the field. Your tiny screen will soon be full of circles! This is a very difficult, funny and really fascinating task!
