A Minigame is a (usually short) segment of a video-game that uses a different style of gameplay than the rest of the 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.

In the Mortal Kombat series, minigames made their first appearance in the first Mortal Kombat, with the Test Your Might minigame. Since then, several minigames have been added to the series in its various other installations.
