What are blockchain games?

Blockchain games are games that utilize smart contracts and token standards for various purposes. Most blockchain games are built with popular game development software like Unity but they also take advantage of blockchain technologies to empower their users and offer a different, unique gaming experience. Blockchain games use ERC-721 tokens for representation of in-game items on the blockchain as non-fungible tokens. With blockchain games, gamers have true ownership of their in-game assets and are able to freely trade their assets with other gamers.
