Play Super Butt Bros 3 (SMB3 Hack) Online

Game Overview

Super Butt Bros 3 (SMB3 Hack) is exactly what it sounds like—a goofy, messed-up version of Mario 3 where everything feels slightly off. The first thing you notice is the sprites. Mario’s got a weird grin, enemies look like they were drawn by a kid who just discovered MS Paint, and the levels have this janky charm.

It plays like Mario 3 at its core, but with bizarre tweaks. Some jumps feel floatier, power-ups do unexpected things, and the stage layouts occasionally throw in some mean surprises. I remember hitting a block expecting a mushroom and getting a giant pixelated fart cloud instead.

Not all the changes work—some stages are just frustrating with unclear hazards—but the sheer absurdity keeps it entertaining. Super Butt Bros 3 (SMB3 Hack) is the kind of romhack you play when you want something familiar but also completely stupid.
