https://github.com/dantrinh/cryptoathletesCryptoathletes are digital collectible football athletes built on the Ethereum blockchain. They can be bought and created using Ether and can battle or faceoff against other users' Cryptoathletes.
Each athlete's token possesses offensive and defensive attributes that affect whether it will be victorious in a faceoff against another athlete's token. Any new user of Cryptoathletes can create one free random athlete for themselves after joining the game. Additional athletes are available for purchase through a pack system. Like popular App Store games, such as Hearthstone, users can purchase packs of these digitally collectible players (two athletes per pack) using Ether.
