A networked computer system for displaying images associated with non-fungible tokens (NFTs) on electronic gaming machines (EGMs) is described herein. The networked computer system includes a computer server coupled to a plurality of EGMs located within a casino property. The computer server includes a processor programmed to execute an algorithm to display an animated sequence of computer-generated images on a display device of a corresponding EGM including the steps of querying a blockchain system to identify a casino charm NFT owned by a casino patron, querying a charms content database to retrieve image data associated with the identified casino charm NFT, and rendering an image of the identified casino charm NFT on a game screen displayed on the corresponding EGM.
