Do you need someone to teach you how to earn stamps and more information about them? Well, then you have come to the perfect place. There are 4 difficulty levels of stamps: Easy (green), Medium (yellow), Hard (blue) and Extreme (red). Some are for all penguins and some are for members. Currently, 352 stamps are available to be earned. The Stamp Book is used to collect stamps. Each individual penguin has his/her own Stamp Book. In the Stamp Book, the stamps are divided into 4 general sections. Some of these sections also have sub-sections. For example, in the "Games" section, there are sub-sections devoted to individual games. For some unknown reason, you cannot get a stamp if you did an effort before the time stamps were released, meaning you have to do it again. However, you would get the 365 days stamp, and the 183 days stamp if you were older than those days before or upon the arrival of the stamps.
