A digital collectible card game (DCCG) or online collectible card game (OCCG) is a computer or video game that emulates collectible card games (CCG) and is typically played online or occasionally as a standalone video game. Many DCCGs are types of digital tabletop games and follow traditional card game-style rules, while some DCCGs use alternatives for cards and gameboards, such as icons, dice and avatars. Originally, DCCGs started out as replications of a CCG's physical counterpart, but many DCCGs have foregone a physical version and exclusively release as a video game, such as with Hearthstone.
