Yes, it is possible to build games on blockchain technology. Blockchain provides a decentralized and secure environment for creating and running games, which can enable unique features and benefits for players and developers.

In addition to the benefits of decentralization and security, blockchain-based games can also provide players with ownership and control over their in-game assets, as well as the ability to earn cryptocurrency rewards or trade items with other players.

So, blockchain game development on top of any blockchain will be profitable for startups and enterprises who wish to start a blockchain-based gaming platform.
