Play Mario Mappy (Mappy Hack) Online

Mario Mappy is a fan-made hack of the 1984 NES game Mappy, originally developed by Namco. It reimagines the arcade-style chase and collection gameplay with Mario characters and themes, fitting right in with the kind of creative, unofficial modifications that began circulating among NES enthusiasts in the late 1980s and early 1990s.

You control Mario as he moves through a multi-story house, bouncing on trampolines to reach higher floors while collecting coins and avoiding enemies like Meowkies (reskinned versions of the original Mappy enemies). The goal is to gather all items on a screen before advancing, with doors offering temporary escape from pursuers. The pacing is fast and tense, as enemies respawn quickly and narrow corridors limit your movement. It feels like a race against time where every jump and door slam matters.
