A minigame, sometimes called a subgame, is a short video game often contained within another video game. A minigame is always smaller or more simplistic than the game in which it is contained. Minigames are sometimes also offered separately for free to promote the main game.

Minigames occur variously as gameplay features, or as time fillers while levels are loading, or as Easter eggs. In the latter case, they are often called "secret games". In the former case, the successful completion of such minigames may or may not be required to finish the encompassing game.

The Final Fantasy series is notable for featuring minigames in every entry of the series, ever since the first Final Fantasy (1987), in which a sliding puzzle in the form of an Easter egg can be unlocked while boarding the ship. In Final Fantasy II (1988), a matching game can be unlocked while boarding the ice sled and meeting a certain requirement. Later in the series, Final Fantasy VII (1997) was the first videogame to include within it at least thirty minigames, which remains the largest number of minigames for a role-playing game.
