minigame

A minigame (also spelled mini game and mini-game, sometimes called a subgame or microgame) is a short game often contained within another video game. A minigame contains different gameplay elements and is often smaller or more simplistic than the game in which it is contained.
Some video games consist entirely of minigames which tie into an overall theme, such as Olympic Decathlon (1980). Minigames can also be used to represent a specific experience, such as hacking, lock picking, or scanning an area, that ties into a larger game.
