Axie Infinity (AI) is an Ethereum-based game that offers NFT collectibles. It was originally an inactive browser game. But the developer made a major overhaul on December 19, 2019 that turned it into a turn-based active RPG with trading cards and monster breeding components. Like other collectible card games, Axie Infinity requires each player to build their own game. However, AI gives the idea a new twist by making each deck a product of a team of monsters controlled by the player.
Each player builds a collection of “axies,” NFT-supported creatures that can be bred and traded. From this collection, the player assembles a team of three axies to use in the current fight.
