Play Unnamed Mario World Online

Game Overview

Ever stumble across something that feels like it was plucked straight out of your childhood, even if you’ve never seen it before? That’s Unnamed Mario World—a fan-made SNES romhack that nails the magic of the original Super Mario World while sneaking in its own personality. The first level alone hits you with that familiar bounce-and-run flow, but then you spot a weird mushroom or a hidden pipe that definitely wasn’t in the official game. Suddenly, you’re grinning like an idiot, half-expecting a Nintendo Power hotline tip to pop up.

Whoever made this clearly spent way too much time studying how Mario moves—the controls are butter-smooth, and the levels have that perfect mix of "easy to pick up, tricky to master." Some secrets are downright devious, tucked behind layers of classic platforming misdirection. It’s not just nostalgia bait, either; there are legit clever twists that’ll make you pause and rethink how you approach jumps and enemies. Feels like digging up a lost beta version from some alternate universe where Nintendo kept cranking out SNES gems.

If you’ve ever thought, "I wish there were just one more Mario World level," this is your fix. Just don’t blame me when you lose an afternoon to it.
