==History==
===''Donkey Kong''===
In the ''Donkey Kong'' arcade game, jacks are constantly bouncing and dropping near [[Donkey Kong]] on [[75m]]. If [[Mario]] gets hit by a jack, he loses a life. Jacks do not appear in the ColecoVision and TI-99/4A ports of ''Donkey Kong'' due to technical limitations. However, they do return in the ''Donkey Kong'' arcade game port included in ''[[Donkey Kong 64]]''. The [[Trampoline|jump board]] from ''[[Donkey Kong Jr. (game)|Donkey Kong Jr.]]'' closely resembles a jack.

In the [[Donkey Kong (Game Boy)|Game Boy version]], jacks are thrown by Donkey Kong instead of spawning from his position. Negating them with a [[handstand]] causes them to fall off-screen like most enemies and obstacles, instead of becoming usable like [[barrel]]s.

===''Mario vs. Donkey Kong 2: March of the Minis''===
In ''[[Mario vs. Donkey Kong 2: March of the Minis]]'', jacks appear in B2 in [[DK's Hideout]], where they have spikes on their top and bottom sides as a visual indicator of their harmfulness. They act identically to their appearance in ''Donkey Kong'', spawning from Donkey Kong's position and bouncing towards the [[girder]] structure below. If a [[Mini Mario (toy)|Mini Mario]] without a shield comes into contact with a jack, the Mini Mario breaks.

===''Super Smash Bros.'' series===
In ''[[Super Smash Bros. Brawl]]'', ''[[Super Smash Bros. for Wii U]]'', and ''[[Super Smash Bros. Ultimate]]'', jacks are a hazard in [[75 m (stage)|75 m]]. The sprite of Donkey Kong at the top of the screen periodically activates, and when that happens, jacks bounce from the left, acting in much the same manner as the original version. In ''Wii U'' and ''Ultimate'', the Ω form of the stage does not feature jacks, and in the latter, jacks as well as other stage elements more closely resemble the arcade version instead of the [[Family Computer]] and [[Nintendo Entertainment System]] version.
