How To Play CryptoKitties

The blockchain world has created a remarkable story called CryptoKitties, where you can buy, breed, and exchange virtual cats. But let me guess, are you wondering what it is and how it all works? Well, you've come to the right place.

Fun Fact: CryptoKitties became so popular in December 2017 that it represented 25% of all Ethereum traffic.

The CryptoKitties Beginner's Guide will show you everything you need to know about starting a story, how genetic algorithm technology works, and, most importantly, how to play CryptoKitties.

What are CryptoKitties?

CryptoKitties was created in December 2017 by the Canadian startup Axiom Zen. AxiomZen is involved in many things, such as software development and virtual reality, but CryptoKitties is one of their most successful projects to date.

The founders wanted to create an Ethereum game that would allow anyone in the world to own a virtual cat created from a smart contract. Each cat created is different with unique traits.

There are also several genders of CryptoKitty, which are named after male or female horses. The male CryptoKitty is called the father and the female named Dames.

Think of it as human DNA. Everyone has their own individual DNA. Well, it’s the same for CryptoKitties. The technology that supports this is known as the genetic algorithm. Some cats have much rarer DNA than others and can be sold for a lot of money. In some cases, over $100,000 was paid for them.

Are CryptoKitties a Cryptocurrency?

CryptoKitties are not a cryptocurrency. Unlike cryptos like Bitcoin and Ether, CryptoKitties have no value outside the network and cannot be exchanged for other tokens or digital currencies in third party exchanges. However, CryptoKitties are "blockchain assets" because people are willing to pay for them.

CryptoKitties are an Ethereum ERC-721 token. ERC stands for Ethereum Request for Comments. There are many variations in ERC, with ERC-20 being the most common. However, ERC-20 tokens are indistinguishable from each other, meaning they’re interchangeable.

How Does It Work?

As mentioned earlier, CryptoKitties are digital collectibles that can be traded, bought, sold, and collected like traditional collectibles. But the thing is that, unlike traditional collectibles, you can commingle the encryption collection, which will result in an offspring: a new baby CryptoKitty.

And since ownership of these collections or CryptoKitties is securely tracked on the blockchain, everything is recorded on the transparent Ethereum blockchain so you don't have to worry about ownership or fraud.

How To Play CryptoKitties

1. Buy Ethereum:

  • Before you start using CryptoKitties, you must purchase Ethereum (ETH). The easiest way to do this is to use Coinbase, as you can quickly and easily buy some with your debit/credit card or bank account.

2. Install MetaMask:

  • After purchasing ETH, you must install Crome extension and virtual wallet, MetaMask. It is a wallet compatible with the CryptoKitties platform, in which you can buy, breed, and sell cats.

  • Send some ETH to your MetaMask wallet.

3. Create a CryptoKitties Account:

  • Now that you have an ETH-funded MetaMask wallet, you can access the CryptoKitties website and create an account.

  • You must first enter your email address and select your nickname. The MetaMask wallet address will be entered automatically, as shown in the screenshot below.

  • CryptoKitties' terms and conditions will be displayed. Make sure to read it before accepting it.

  • The MetaMask pop-up will then ask you to log in to CryptoKitties. Click Login

  • You should now see the CryptoKitties platform. In other words, you have successfully opened your account.


After reading this guide, you should be familiar with how genetic algorithms work. It's cool that smart contract technology works just like DNA, don't ya think?

Now, you can use the CryptoKitties and breed a few of your own CryptoKitties.
