Blockchain has unlocked the magic of digital scarcity, and combining that with the power of making the digital goods persistent gives them a potential value that is only limited by how much prestige a wealthy person might place on ownership of the item.
3 days of up and 19 days of down down down... And the 3 up days were right at the start. Yeah, looking real good.
Nobody wants to pay $300 for a hexadecimal string. That's LITERALLY all you’re buying. All the website does is display a picture of a cat. You're paying hundreds of dollars for a picture of a cat. Let that sink in.
This was a modern tulip bubble. You were buying hex strings that tied to the picture of a cat. People were paying 10-20-30 ETH for a cat picture. 10 ETH was around $4000? For a cat picture. Yeah...

Collectible. Breedable. Adorable.
Collect and breed digital cats. Start meow. Buy! Sell! Hold!
Q: What's CryptoKitties? What's the big deal?
CryptoKitties is 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.
CryptoKitties is built on blockchain technology. You can buy, sell, or trade your CryptoKitty like it was a traditional collectible, secure in the knowledge that blockchain will track ownership securely. But, unlike traditional collectibles, you can breed two CryptoKitties to create a brand-new, genetically unique offspring. It results in something special—just like you!
(*): See Q: Do you really own your CryptoKitties? A: Spoiler: No.

If you are going to build consumer [gambling casino] products on the internet [blockchain] then you should not explain why you're using cats, but you should explain why you are not using cats.

Official WikiLeaks CryptoKitties. Purebred WikiLeaks CryptoKitties arrive in time for Christmas.
How it works. Mr. WikiLeaks and Mrs. WikiLeaks are two Generation 0 CryptoKitties. WikiLeaks will keep scarcity by breeding only one kitten per week after the initial Christmas litter of 10 (of which only 8 will be for sale). Kitties can be renamed and resold or gifted by their new owners. Their authenticity can be verified on the blockchain. WikiLeaks CryptoKitties will be auctioned at a variety of prices, starting at the highest bidding price which will decrease over the course of the four day auction or until a buyer acquires the kitty.

CryptoKitties marks the beginning of a (massive) digital revolution. To understand why, learn about the blockchain, blockchain, blockchain.
Why we’re not doing an Initial Coin Offering (ICO) by Benny Giang (Axiom Zen, Vancouver, Canada), November 2017
CryptoKitties is not holding an Initial Coin Offering (ICO). Instead, we're offering utility from day one and pursuing a sustainable revenue model based on our games' mechanics.
CryptoKitties offers something similar to a cryptocurrency: each CryptoKitty is one-of-a-kind, 100% owned by the user, validated through the blockchain, and the value can appreciate or depreciate based on the market. Cryptokitties cannot be replicated, taken away, or destroyed.
CryptoKitties & Fun-tier Technologies by Vijay Sundaram, December 2017
These tokens ought to primarily flow to users and partners who participate in a well-designed economy, rather than just speculate on it. Almost by definition this approach will pay off even if the crypto tide goes out.
People are spending $millions on digital cats and here's why it makes sense by Tony Aubé, December 2017 -- Crypto Kitties is about so much more than cats.
The blockchain changes everything we thought we knew about computers. By removing one of the computer's biggest feature - the ability to duplicate information - it opens up computing to a multitude of new, real-world use-cases that would have never been possible before.
Gambling with CryptoKitties - Welcome to the Casino - Get-Rich-Quick
(Source: CryptoKitties have the digital currency world purring, The San Francisco Chronicle)
- The founder auctioned off 100 founder gen 0 kitties on startup.
- The founder auctions off a new gen 0 kitty every 15 minutes until reaching 50 000 gen 0 ktties in November 2018. Note: The auction price gets automatically calculated from the last five sales plus 50%.
- The founder get a 3.75% cut (no minimum) on every transaction (selling auction, siring auction, etc.) on the official CryptoKitties marketplace.
Note: If you buy kitties you do NOT own the pictures (*) just the 256-bit hex string (on the blockchain), thus, the founder can sell merchandise or license the pictures for profit. What a franchise!
(*): See Q: Do you really own your CryptoKitties? A: Spoiler: No.
No. 1 - Sell your kitties to a greater fool for a higher price!
No. 2 - Put up your kitties for siring (breeding) a new kitty in an auction and earn money for the service! The rarer your kitties traits the higher your service fee income!
No. 3 - Breed your own new kitties and sell to a greater fool for a higher price!
Buyer Beware! Seller Beware! Here Be Dragons!
Scam #1: Selling Fake Labeled Cheap Kittens Expensive to Newbies (First Timers)
It's like selling (fake) cheap Gucci handbags for the expensive Gucci price. Best of both worlds. Buy low, sell high :-). Profit!
Example: I list my gen 15 cat for sale and name it "RARE gen 0 SANTA mom" and new people not yet understanding how things work buy it. That was happening ALOT.
Q: Can you please return the cat names to the breeding screen?
Benny Giang: Cat names was an awesome way to have personality in the marketplace but unfortunately, there were too many people taking advantage and tricking new users.
Scam #2: Fake Services Phishing (Stealing) Your Private Keys (Kitties)
Put up a website that offers to find the perfect soul mate (with machine learing) for siring new kitties with the rarest of the rarest traits. Please enter your private key to get started. Thank you! Now you've got new kitties for free. Profit!
REMINDER: Trading or selling kitties off of the CryptoKitties marketplace can put your account at EXTREMELY HIGH RISK. NEVER expose your private key on any website for any matter at all. If you do so, you put yourself in a vulnerable position!

Is CryptoKitties a Scam? Is CryptoKitties a Pyramid (Gambling) Scheme? Is CryptoKittes an Online (Gambling) Casino?
First the official answer from the CryptoKitties F.A.Q.:
No, this isn’t a scam. Anyone with insider knowledge of CryptoKitties - including our developers - are banned from participating. This is to prevent anyone from using their knowledge of the breeding algorithm to create the most valuable kinds of cat.
CryptoKitties are NOT a cryptocurrency. They're more like a crypto collectible. The real-world analogy for a cryptocurrency is dollars or pounds; a crypto collectible’s real world analogy is closer to stuffed animals beanie babys or fine tulip flower bulps.
As dictated by the contract script on the blockchain, any CryptoKitty you own belongs to you (*). Like any product or property you can own, the market price is determined by what a greater fool is ready to pay (depending on demand, scarcity, and only limited by your asking price).
(Source: CryptoKitties F.A.Q.)
(*): Note: See Q: Do you really own your CryptoKitties? A: Spoiler: No.
And here's an independent ("unofficial") answer:
Yes, of course. It's gambling. CryptoKitties is designed on purpose for viral spreading.
With human nature is what it is - fear of missing out of getting-rich-quick and so on - it works everytime like a charm once the hype starts (and prices go up and up).
More and more new greater fools buy more and more 256-bit hex strings (kitties on the blockchain) until in the end running out of new greater fools paying ever higher prices.
Facebook has more than 1 000 000 000+ internet user. CryptoKitties is world-wide. Will CryptoKitties ever run out of new greater fools?

Gambling vs Investing
Investments are generally not considered gambling when they meet the following criteria:
- Economic utility
- Positive expected returns (at least in the long term)
- Underlying value independent of the risk being undertaken
For example, the mixing of genomes when breeding (siring) new kitties is a modern "masqueraded" or fun way to roll a dice or spin a roulette wheel. The betting (wagering) on rare traits is a modern "masqueraded" or fun way of betting (wagering) on lucky numbers.
And, of course, the kitties are a modern "masqueraded" or fun way of casino "funny money" tokens rebranded as digital "virtual" cat collectibles or non-fungible tokens (N.F.T.s).
BEWARE: Gambling is fun and addictive. Winning and losing. Up and down. Treat CryptoKittes as entertainment like casino gambling, sports betting or poker cards playing. Do NOT "invest" trying to get-rich-quick or raise the stakes trying to win back what you have lost, and so on.

A: Crypto-collectibles have key properties that proprietary digital collectibles didn't: longevity, code-enforced scarcity and rules, resistance to actions of sponsoring company. Much closer to non-digital collectibles like baseball cards than pre-crypto digital goods.

A: Spoiler: No.
CryptoKitties are made up of two pieces: the DNA written to the blockchain, and the graphics assembled to represent each CryptoKitty. Axiom Zen owns the graphics, and makes it clear you have no rights to those in their Terms of Use.
A: Costs:
- Buying a cat. (For sale / Buy now price varies; see Marketplace / For Sale)
- Hiring a sire for your cat. (Want to sire / Breed now price varies; see Marketplace / Siring)
- Breeding @ 0.008 ETH (*)
Fees:
- 3.75% Sales fee. (When you successfully sell or sire a cat on the marketplace.)
- Gas fees (**). These are transactions fees. Every time you start a transaction on the blockchain, you have to pay the "miners" to run the task. Transactions with gas fees incl.:
- Buying a cat / hiring a sire.
- Breeding.
- Putting a cat up for auction (sell or sire).
- Taking a cat down from auction (sell or sire). [Note: Note: If you cat doesn't sell, it stays up for auction until you take it down.]
(*): The breeding fee was at first 0.001 ETH. Due to high transaction traffic on the blockchain the founders had to raise the fee because the breeding fee has to be higher than gas fees to birth a new kitty.
(**): The gas fee is shown before you send off a transaction. It is roughly between $0.30 - $3.00 (depending on blockchain traffic).
A: 50_000 Gen 0 Kitties
- CryptoKitties started with 100 founder kitties - see #1 (Genesis!) to #100.
- Every 15 minutes a new gen0 kitty (also known as "clock cat") gets added (that is, 4 gen0 kitties/hour, 96 gen0 kitties/day, 672 gen0 kitties/week) and sold by (dutch) clock auction (*) until reaching a limit of 50_000 in one year (end of November 2018) - see #1001 for first clock cat.
(*): A gen0 kitty's start price is automatically calculated by the average price of the last five kitty sales, plus 50% and sold by a descending clock auction; see Marketplace / Gen 0.
(Source: Statistical Data on CryptoKitties)
It's an auction with an automatically calculated descending price by clock (that is, the prices depends on the time of the purchase). Sellers choose a high opening bid, a minimum closing bid, and a timeframe for the auction to run. Buyers choose their purchase price along that spectrum by purchasing when the price aligns with their perceived value of the CryptoKitty being sold - as long as someone else doesn't buy it befor. Note: Buyers pay gas when they complete a purchase and sellers pay gas to start an auction.
A: The generation, cooldown speed, traits, and all affect the overall price and desirability of the kitties. Generally, anything gen(eration) 0/1/2/3/4, with fast/swift/snappy/brisk is a good kitty. Rare traits make it even better.
Generation. The best generation of kitty is Gen 0. The lower the generation number, the better starting cooldown the kitty is born with.
When breeding two kitties together, the resulting generation will be one higher than the highest generation parent. For example:
- If a Gen 0 and Gen 0 breed, the kitten will be Gen 1.
- If a Gen 5 and Gen 5 breed, the kitten will be Gen 6.
- If a Gen 0 and a Gen 5 breed, the kitten will be Gen 6.
Cooldowns. Each time a kitty breeds another kitty it needs a period of cooldown time to recover. The cooldown wait time increases every time a kitty breeds until it reaches "catatonic" cooldown, where it will remain.
Note: Cooldowns -
fast (1m) › swift (2m·5m) › snappy (10m·30m) › brisk (1h·2h) ›
plodding (4h·8h) › slow (16h·24h) › sluggish (2d·4d) › catatonic (1w) -
are NOT inherited but depend on the generation, that is,
each new kitty is born with a cooldown based on its generation (gen).
| Gen | (+) Kids | Cooldown | Time to Recover |
|---|---|---|---|
| 0 · 1 | Fast | 1 minute | |
| 2 · 3 | Swift | 2 minutes | |
| 4 · 5 | -^^^- | 5 minutes | |
| 6 · 7 | Snappy | 10 minutes | |
| 8 · 9 | -^^^- | 30 minutes | |
| 10 · 11 | Brisk | 1 hours | |
| 12 · 13 | -^^^- | 2 hours | |
| 14 · 15 | Plodding | 4 hours | |
| 16 · 17 | -^^^- | 8 hours | |
| 18 · 19 | Slow | 16 hours | |
| 20 · 21 | -^^^- | 24 hours | |
| 22 · 23 | Sluggish | 2 days | |
| 24 · 45 | -^^^- | 4 days | |
| 26+ | Catatonic | 1 week |
Examples:
A gen 2 kitty will start off with a swift 2 minutes cooldown when born, and a gen 14 will be born with a plodding 4 hours cooldown.
A gen 11 kitty virgin will start off with a brisk 1 hours cooldown (slot gen 10·11) when born, but after having 3 kids will end up 3 slots down with a plodding 8 hours cooldown (slot gen 16·17).
Traits. Certain traits are rarer than others, making the Kitty more desirable. As more kitties are bred with these traits and new traits are discovered, the value of each one can change.
Traits include:
- Body and Tail: Chartreux Cymric Himalayan Laperm Mainecoon Munchkin Ragamuffin Sphynx

Q: Where do you see CryptoKitties 6 months from now?
Arthur Camara: 6 months from now: there'll be tons of new genes, fancy cats, new features that enhance the gameplay. Managing larger collections will be easy and fun. Cats of all prices will be meaningful and we'll find new ways for people to play with their kitties. We want to enhance the meaning of ownership and make it even more fun.
Q: We have 365k kitties now and under 196k total sales (kitties traded or sired). That combined with the drop in values suggests that the demand isn't keeping pace with the supply [...] causing the market to tank. What do you think caused the crash? Are you working on strategies to increase kitty values or do you want the value to stabilize at $1 per cat or so as rumored?
Q: Any plans to make the market more sustainable for small investors? Currently, someone who invests only $10 can barely buy two kitties, let alone cover the cost to breed them. To make that worse, the likelihood that they'll be able to sell the offspring is minimal. What's your take?
Q: Any modification in plan regarding the mass supply of Gen 0s overcoming the demand?
Mack Flavelle: To be honest, the market has been unpredictable for users and for us. We don't have any more visibility on what will happen next than any other user.
The market excelled much more quickly than we expected - the Gen 0 pricing is 50% more than the average of the last 5 kitties so it is completely determined by the market not us.
We really do believe that long term the kitties will capture a ton of value for users and fans, but it's important to remember that CryptoKitties is a decentralized game. We have very little control on the economy for good or for bad.
Q1 of 2018 we have plans to stabilize the economy and reduce the volatility - in the long run we believe the kitties will be valuable.
Over time the economy will expand to be truly fun and valuable for high net worth players and new, exploratory players - a bigger, healthier economy creates value for everyone inside it.
Arthur Camara: I believe we're building long term value to CryptoKitties with amazing features that are coming, new ways to play with the kitties, new interactions. And remember: there will only ever be 50,000 gen0 kitties, we are constantly adding features, fancy kitties are constantly being discovered.
Benny Giang: There are some interesting ideas around limiting the supply of kitties that we will explore in 2018.
Q: Please let us have an option to recycle / trash worthless kitties in exchange for something.
Benny Giang: Yup, a "kitty sink" could be useful for the market but there are also various of other viable solutions.
Q: Where do you see CryptoKitties 6 years from now?
Arthur Camara: CryptoKitties will be a global brand (way before that, actually). People will give CryptoKitties to their children on their first birthday. There'll be a complex ecosystem around the game, with lots of features and tools.
The day-one functionality of the contract scripts includes:
- Keep track of the genes of upcoming gen0 CryptoKitties
- Introducing the genes of gen0 CryptoKitties to the Core Contract
- Launching the auctions for gen0 CryptoKitties (including price determination)
- Combining the genotypes of two parent CryptoKitties to determine the genotype of the new CryptoKitten
- Managing the auctions of CryptoKitties (both gen-0 cats being auctioned to users and user-to-user auctions) and siring tokens
- Managing siring auctions (including initiating the breeding when successful).
All functionality for breeding, buying, selling, and transferring cats will be possible for any user by interacting directly with the contracts on the blockchain. Any auctions or sales conducted through our auction contract will include a 3.75% commission (no minimum) taken from the seller's portion.

CryptoKitties is composed of 4 public facing contracts. Below we'll provide an overview on these contracts:
Also referred as the main contract, is where Kitties and their ownership are stored. This also mediates all the main operations, such as breeding, exchange, and part of auctions.
For this release, the actual bytecode released for the contract is
KittyCoreRinkeby.sol, explained below.Where users are expected to acquire their gen0 kitten. It is also a marketplace where anyone can post their kitten for auction. See Dutch/Clock auction - note we also accept an increasing price. ps: CryptoKitties auctions take an initial time and duration, and after duration is over they are not closed. Instead they hold the final price indefinitely
A marketplace where any user can offer their Kitty as a potential sire for any takers.
It's a mystery! Not public for this release.

The 256-bit genome (genes) have over 4-billion variations of phenotypes (what you see) and genotypes (what you don't see).
The CryptoKitties Genome Project by Kai, Dec 19
Here's what I've found:
- Genes are stored in 12 blocks of 4x5-bit codes
- Each 5-bit code represents a cattribute associated with the position in the gene (body, pattern type, eye color, eye type, primary color, pattern color, secondary color, fancy type, mouth)
- Each block of 4 codes represents 1 dominant trait expressed in the Kitty followed by 3 recessive traits.
- Codes are passed from either parent to child, with a low probability of swapping from the 1st recessive, and a lower probability of swapping from the 2nd or 3rd recessive. [...]

The CryptoKitties Genome Project: On Dominance, Inheritance and Mutation by Kai, Jan 6, 2018 -- Genome, deciphered
The genome represents 12 groups of 4 genes. Each group of 4 genes maps to a given cattribute trait. Within each group of 4 genes, there are 3 recessive genes [R1, R2, R3] and 1 dominant gene [D1] which will be reflected as a cattribute for that trait, represented in the appearance of that kitty.
[...]
Here is a quick sketch of the relative odds of getting a specific gene from the parents
- 75% - either dominant gene [D1] from parent A or B
- 18.75% (75/4) - chance of getting either 1st recessive [R1] from A or B
- 4.69% (75/4²) - chance of getting either 2nd recessive [R2] from A or B
- 1.17% (75/4³) - chance of getting either 3rd recessive [R3] from A or B
- 25% - chance of getting a mutation given A & B contain the right gene pairs
Q: What's kai notation (base58)?
Kai notation (named to honor Kai who deciphered the kitties genome) is a base58 variant for decoding the 256-bit integer into 5-bit blocks. Each 5-bit block is a gene. The 256-bit genome breaks down into 12 groups of 4 (x 5-bit) genes (that is, 12 x 4 x 5-bit = 240 bits) Example:
| Kai | Binary | Num | Kai | Binary | Num | Kai | Binary | Num | Kai | Binary | Num |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 1 | 00000 | 0 | 9 | 01000 | 8 | h | 10000 | 16 | q | 11000 | 24 |
| 2 | 00001 | 1 | a | 01001 | 9 | i | 10001 | 17 | r | 11001 | 25 |
| 3 | 00010 | 2 | b | 01010 | 10 | j | 10010 | 18 | s | 11010 | 26 |
| 4 | 00011 | 3 | c | 01011 | 11 | k | 10011 | 19 | t | 11011 | 27 |
| 5 | 00100 | 4 | d | 01100 | 12 | m | 10100 | 20 | u | 11100 | 28 |
| 6 | 00101 | 5 | e | 01101 | 13 | n | 10101 | 21 | v | 11101 | 29 |
| 7 | 00110 | 6 | f | 01110 | 14 | o | 10110 | 22 | w | 11110 | 30 |
| 8 | 00111 | 7 | g | 01111 | 15 | p | 10111 | 23 | x | 11111 | 31 |
Note: The digit-0 and the letter-l are NOT used in kai.
Base58 is a group of binary-to-text encoding schemes used to represent large integers as alphanumeric text. It is similar to Base64 but has been modified to avoid both non-alphanumeric characters and letters which might look ambiguous when printed [e.g. 1 and l, 0 and o]. It is therefore designed for human users who manually enter the data, copying from some visual source, but also allows easy copy and paste because a double-click will usually select the whole string.

CryptoKitties mixGenes Function by Sean Soria, Dec 22

We want to have a presale first so we can raise funds to hire more devs and artists and pay for scalable infrastructure, to have a really great and responsive game. We are working out the legal aspects of the presale right now, because there is a lot of uncertainty right now around crowdfunding with cryptocurrency.

The first five animals to be sold off...
Please welcome the Dog, Galapagos Turtle, Giant Panda, T-Rex and Unicorn
as the founding species on CryptoPets!
CryptoPets are the newest breed of animals on the block... blockchain that is. Unlike cryptocurrencies, which require all tokens to be identical, your CryptoPet will be the only one of its kind in the entire world. These cute collectibles are cryptographically unique, non-fungible digital assets. CryptoPets uses the immutability of blockchain technology to verify and prove that each CryptoPet has its own special attributes and is entirely owned by you.
Each species will have variations in specific attributes, including fur color, eye shape, paw, and feet type, to name a few.

Hero Tavern is a decentralized app that based on Ethereum platform. It is also a classic Simulation game. In the Game, player can acquire Heroes via many different ways. For example, Heroes can be purchased directly from the Market. Some of those Heroes are generated by System, and some are put up for sale by other players. After players own at least one Hero, they can begin journals of training and cultivating their Heroes. Every Hero has talent values; these values pretty much determine the combat power of a Hero at certain level. If players do not satisfy heroes’ talent, they can wash talent. In order to have higher Combat Power, Heroes can equip better equipment or cumulate Exp to upgrade Levels. Firstly, Players can assign Heroes to fight and suppress Monsters. Players will gain weaponry of Heroes and Heroes will gain Exp. Also, there is a chance that a Hero can be rescued from Monsters. Secondly, Players can buy Treasure Maps from Auctions, then Heroes is able to go for Treasure Hunts. It is possible to meet a new Hero during the Treasure Hunt beside the chance of finding rare items. Moreover, if Players do not like or need their Heroes, and also do not want to put Heroes on Market to sale, the Factory offers Players another way to deal with their useless Heroes. By adding items, Players can recast their Heroes to generate a new one. Alternatively, Players can just simply dissolve their Heroes into items and bottles of Exp. There are more fun and more surprises for you to explore in the Game. There are more unique Heroes are waiting for you to collect. New Adventures are on the way!

Game concept
Player owns fishes (those are in fact ERC-721 crypto tokens) each with its unique name, image and characteristics defined by type. Core fish parameter is weight that defines its size and influence. Main target is to grow this parameter to become the biggest fish in the ocean. Fish is able to gain weight only by attacking other fishes, biting off them in case of win.
The more powerful characteristics and the more weight the fish has the more chance it to win a fight with another fish it represents.
These fishes can be traded or exchanged between players on central fish market. Every operation in the game is launched and controlled by a contract script.
The Fish
Every crypto fish token has its own set of characteristics:
- Weight - Describes the size of the fish
- Power - Damage on attack
- Agility - Defense on attack
- Speed - Cooldown time before attacks
Weight is dynamic characteristic and can be changed within time while Power, Agility and Speed are called initial parameters those are given to fish from the very moment of creation and can't be changed in time.
Rarity
There are four kinds of rarity assessment for fishes determined by sum of all initial fish characteristics:
- Common
- Rare (10+)
- Legendary (15+)
- Epic (25+)

Q: What's different?
Too simple. Buy, sell and hodl (collect). That's it. Fixed 10 000 collection. No new CyperPunks creation (eg. pairing of genomes) possible. No growth. No "mystery" genome and new surprise genes and attributes etc. Where's the fun? :-).
