A programming game is a video game that incorporates elements of computer programming, enabling the player to direct otherwise autonomous units within the game to follow commands in a domain-specific programming language, often represented as a visual language to simplify the programming metaphor. Programming games broadly fall into two areas: single-player games where the programming elements either make up part of or the whole of a puzzle game, and multiplayer games where the player's automated program is pitted against other players' programs.
