Formally, a computer game is a game composed of a computer-controlled virtual universe that players may interact with in order to achieve a goal (or set of goals). A video game is a computer game where a video display is the primary feedback device.

However, in common usage "computer game" refers to games played on a personal computer, while "video game" (or "videogame") refers to games played on a video game console. Both "computer games" and "video games" are frequently used as umbrella terms for interactive game software. To avoid ambiguity, this game software is referred to as "computer and video games".
