The game is a combination of:

Tamagotchi, where you raise your pet from an egg to an adult, being happy or sad, does impact its development.
Pokemon to try and catch them all!
Blockchain as it is based on ETH blockchain

Ethergotchi!

You can now get a free egg either by claiming an alpha egg, 30 eggs are available every 6 hours for the taking until Feb 9th.Or by getting referrals which are valid until Feb 16th, a minimum of 3 referrals is required for a common egg.The studio will be then providing you with CHI tokens based on the number of eggs you have so you can feed it and raise it. The CHI tokens will be distributed for FREE which will eventually, in my opinion, build a loyal community that will enjoy the game.The game will offer an auction house similar to CryptoKitties where you can buy/sell eggs and in-game items. This will be available once the game hit the start after Feb 16th.If you enjoyed the read, you can register via my referral aethia.co
