Play Super Mario Bros 3 - Fun Edition (SMB3 Hack) Online

Game Overview

Super Mario Bros 3 - Fun Edition (SMB3 Hack) is exactly what it sounds like—a tweaked version of the NES classic with some weird, playful changes. The first thing you'll notice is the altered graphics—some sprites look off in a charming way, like someone doodled on them.

The levels feel familiar but just different enough to keep you guessing. Some jumps are tighter, some enemies move in odd patterns, and there are little surprises tucked in corners. It doesn’t reinvent the game, but it’s fun if you’ve played the original to death and want something slightly fresh.

It’s still Mario 3 at its core—running, jumping, collecting power-ups—just with a few quirks that make you double-take. Not a must-play, but a decent romhack for fans who want a twist on the usual formula.
