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.
