Play Mario Brothers Adventures (demo 2) Online

Weird little SNES demo where Mario’s jumps feel just right—you’ll poke at every block hunting secrets, even when the jumps try to mess with you. That *boing* sound when you land on a goomba? Still hits.

Game Overview

Mario Brothers Adventures (demo 2) is an unreleased prototype for the Super Nintendo Entertainment System, developed by Nintendo. It surfaced online years after the console's prime, offering a brief but curious glimpse into an alternate take on the Mario formula during the 16-bit era.

You control Mario through a handful of side-scrolling levels, jumping on enemies and breaking blocks to uncover power-ups and hidden paths. The main goal is simply to reach the end of each stage, but the level design encourages careful exploration, with many false walls and concealed areas rewarding thorough players. The jumping physics feel slightly heavier than in Super Mario World, demanding more precision, especially during sequences with moving platforms or narrow gaps. It's a short, challenging demo that captures the tactile satisfaction of a well-timed jump.
