Play Mario Wednesday Online

Mario Wednesday was never officially released on the Super Nintendo Entertainment System, but it exists as a hacked version of Super Mario World, created by fans. It takes the familiar framework of the original game and twists it into something far less predictable, fitting right in with the era of cartridge mods and early ROM hacking.

You control Mario through a series of altered levels where standard platforming is frequently interrupted by strange events. The main goal remains reaching the end of each stage, but you'll encounter glitched pipes that send you to mirrored or incomplete areas, and power-ups that cause bizarre transformations, like turning enemies into harmless, dancing objects. The pacing is erratic, and the difficulty often feels arbitrary rather than designed. Playing it feels like navigating a dream where the rules of a world you know have been quietly, and sometimes jarringly, rewritten.
