I built a World Cup prediction game Dapp with ERC 721 tokens. Each token holds the entire predictions (64 matches) Each time a World Cup match finishes, your token might earn points if your prediction was correct.

Tokens with more points, will get the reward from the Smart Contract (which operates as a prize pool)

During the World Cup, a secondary exchange will open to trade tokens.
