Club Penguin Stamps were released on July 26th, 2010.You can earn them by meeting mascots, playing games, and working with other penguins. There are 4 difficulty levels of stamps: Easy, Medium, Hard and Extreme. Every penguin has their own stamp book, but only members can earn every stamp and customize their stamp book!
- You can see how many stamps you have earned on your player card.
- You can edit your stamp book by clicking on the pencil on your bottom right corner.
You can only see that pencil if you are a member, if not then you cannot customize your stamp book. Stamps are also a reason that non-members cannot play all of the levels in the Club Penguin Games.
