You have to hit the pengins poping out of the holes in the ice with snowballs! For that purpose, simply click on them with your mouse. When you reach one pengin, you get 10 points and one new snowball. But take care! If you miss, you loose 10 points and do not get a new snowball so that your stock reduces... Beside, the pengins are shooting snowballs also. If you are hit, you loose one life ball that can not be replenished. When you have no more snowball, or no more life ball, you loose. Your stock of snowballs (white) and life balls (red) is shown at the bottom of the screen. Have fun...
