KlayCity is a blockchain-based virtual world where users can buy districts and build their city. Districts are represented by Non-Fungible Tokens (NFT). NFTs are unique digital assets that can be bought and sold on the blockchain. Each district has its theme, such as medieval fantasy, sci-fi future, etc. Each district owner has an opportunity to create their city within KlayCity. District owners can invite other players to visit their city and spend time together. City owners may invite friends to see their city and play games together. The game's main objective is to rebuild your population and gather resources while expanding your territory.
