What are exclusive series?
There are some special series that can only be unlocked with a diamond key; we call these "exclusive" series. The current exclusive series are: Himalayan, Cotton Candy, Bear, Tea, Spirit, Marbles, Sword, Art Nouveau, Valentino, Hat, and Pixie. New exclusive series are added periodically, and are usually announced on our Facebook page
How do I get a diamond key?
Diamond keys are somewhat hard to obtain, but have been found in large presents, awarded as prizes for in-game events as well as Facebook page contests, and rarely, offered for sale. There may be more ways to obtain the special keys in the future, so be sure to watch our Facebook page
Note: Diamond keys are a one-time use item. You'll need to acquire a new diamond key series for each exclusive series you want to unlock, so keep an eye out for events and sales!
