Building An Ethereum Simulation Game – Part 2 – Playing Tennis Matches

In part one, I outlined the idea for a Tennis Manager simulation game on the Ethereum Blockchain. I created the ERC721 Token and the TrainableTennisPlayer contract which enables owners to increase their player stats by training or resting.
