Stamps and Booklets are new ways to acquire exclusive GamePoint items (Daubers, Card Designs, and Avatar Frames) through Personal Missions. 30 Stamps are required to fill in a single Booklet that can be used later in the game to unlock exclusive content as mentioned above! More ways to collect Stamps will be added in the future to help you complete your Booklet even faster!
 
Stamps are automatically added to the active Booklet upon receiving them. If the current Booklet gets filled, the extra Stamps are applied to a new one.
 
You can check your Booklet balance in the Game Items inventory (located in the top bar of the game). Here, both completed and in-progress Booklets can be found.
 
Some Game Items can be purchased exclusively through Booklets, while others can be also be purchased with Coins.
