Site administrator sets up site rules according to which you can gain points. To find out these rules open the "Help" tab in the widget:
As a rule you can get points for first site visiting, link sharing to social network ( Facebook, Twitter etc.), everyday site visiting etc.
The information about bonuses, power moves and opportunities for expression by the aid of which you "earn" or, quite the opposite, you spend points, is displayed in the "Help" tab.
In case you have lack of points, you can always buy points.
