Play Super Mario World 3 - The New Islands Online

You bounce through deceptively tricky levels, hunting hidden P-switches and laughing as Mario turns into a ridiculous floating bubble. Yoshi’s here, the sprites look ripped from a lost SNES cart, and the jumps feel just right.

Game Overview

Okay, so Super Mario World 3 - The New Islands isn’t actually made by Nintendo—but if you didn’t know that going in, you’d swear it was some lost SNES classic. It nails that perfect mix of bright, bouncy Mario vibes and "wait, how do I even get up there?" level design. The first time I played, I got stuck on this one vine-covered cliff for way too long before realizing I needed to bounce off a hidden P-switch. Classic Mario troll logic.

Yoshi’s back (obviously), and there are some wild new power-ups—one turns Mario into this weird floating bubble thing that’s equal parts hilarious and slightly OP. The sprite work is so on-point it hurts, like someone time-traveled to 1994 and stole Nintendo’s dev notes. And yeah, the controls feel exactly like they should: no weird lag, no janky jumps, just pure SNES-era platforming bliss.

Honestly, if you’ve ever yelled at your TV because of a hidden block in the original, this’ll give you that same rage-and-adrenaline cocktail. Just with more surprise Hammer Bros. ambushes.
