# Special Cards

There are special CARDS that offer to claim Card #0. Special CARDS are rare and to know if a CARD is special just access the unlockable content in the 'unlock' section of the [APP](https://mysteriesland.com/books). But only the owner of the CARD can find out if the CARD is special.

Special CARD holders can claim Card #0 by accessing the 'rewards' section of the [APP](https://mysteriesland.com/books).

Card#0, utility token, is a membership card that gives access to special benefits and exclusive spaces, whitelist enrollment and others. The benefits will be stated in the section of each book.
