CRYPTOKITTIES
Overview

CryptoKitties is a game centered around breedable, collectible, and oh-so-adorable creatures we call CryptoKitties! Each cat is one-of-a-kind and 100% owned by you; it cannot be replicated, taken away, or destroyed.

In CryptoKitties, users collect and breed oh-so-adorable creatures that we call CryptoKitties! Each kitty has a unique genome that defines its appearance and traits. Players can breed their kitties to create new furry friends and unlock rare cattributes.

CryptoKitties is one of the world’s first blockchain games. ‘Blockchain’ is the technology that makes things like Bitcoin possible. While CryptoKitties isn’t a digital currency, it does offer the same security: each CryptoKitty is one-of-a-kind and 100% owned by you. It cannot be replicated, taken away, or destroyed

So why cats?
Pop quiz, hotshot: why not?
Cats are impossible to understand. They’re ambassadors for pharaohs, memes, and your mom’s facebook page. They don’t discriminate; they despise everyone equally.

Cats are perfect killing machines, with retractable claws, night vision, and teeth on their tongue. But cats also nap whenever they feel like it, and we respect that.

More than anything, cats are different. They’re weird, funny, and hopelessly entertaining. You don’t have to understand cats to appreciate them.
We’re not trying to build the future—we’re trying to have fun with it.

The future is meow.

Kitty Types


All cats are special, but some are extra special, here's what makes a cat fancy or exclusive.

Cats come in many shapes and styles, and we love them all. There are four official types of CryptoKitties: Normal, Fancy, Special Edition and Exclusive. A Normal cat’s appearance is based on its genetic Cattributes. Fancy Cats have unique art and are created by finding a particular genetic recipe, although their appearance may not reflect the actual Cattribute traits within that recipe. Exclusives are the rarest Kitties, released to commemorate special events and community members. 


Mewtations


When a cattribute is discovered a Diamond mewtation gem is awarded and there can never be another for that trait. Thereafter Gilded gems are awarded for the 2nd to 10th kitty that mewtated this trait, Amethyst for 11th to 100th and Lapis for 101st to 500th. Note: a kitty must mewtate the trait to be awarded the gem. More than one gem can be awarded where applicable.


Cattributes


Every CryptoKitty is made up of 12 cattributes correspondent to its genetic code. You can either buy or breed your purrfect combination.


Fancies


Fancies are CryptoKitties that feature special artwork and are often either time-limited or limited edition. They’re created when Kitties are born with a particular combination of cattributes during Fancies chases with breeders who discover the first becoming Grandmasters. More information about which Fancies are currently available to breed - in addition to the recipe you will need - can be found in the Fancies section of the Catalogue.


Purrstige


Purrstige Traits are Cattributes that are only breedable for a limited amount of time. Every Purrstige Trait has a special recipe that needs both Cattributes and hidden genes. To breed a kitten with a Purrstige Trait, a player needs the right combination of Cattributes and hidden genes in the two parent cats.

Every CryptoKitty is born with a set of 48 genes. Some of those genes are expressed visually; we call those Cattributes, and they define your Kitty’s art, like what shape of ears it has. Others are hidden, and can be found using third-party tools (we’ll hook you up with those later in the article). Purrstige Traits are a very special kind of Cattribute. They’re challenging to breed, rewarding to unlock, and create some of CryptoKitties’ coolest looking cats.

Why breed Purrstige Traits?
Breeding a Purrstige Trait can be challenging, but it’s rewarding too. Because Purrstige Traits are time-limited, they’re particularly rare — and especially valued as a result. Plus, Purrstige Traits are always a nice visual treat, creating some of the game’s most beautiful and unique cats.
