Play Super Mario World 3 Plus - The New Islands Online

Super Mario World 3 Plus - The New Islands is a fan-made expansion for the Super Nintendo Entertainment System, built as a ROM hack of the original Super Mario World. It was developed by enthusiasts in the modding community, not by Nintendo, and it expands the original game with entirely new levels and challenges. It fits right into the SNES library, offering more of the platforming action that defined the era.

You control Mario (or Luigi) through a series of themed islands, jumping on enemies, breaking blocks, and hunting for key items to unlock new paths. The main goal is to reach the end of each stage, defeat the bosses, and rescue Yoshi's friends. Signature mechanics include the cape feather, which lets you fly and glide after a running start, and the addition of new power-ups that change how you approach obstacles. The pacing is brisk, with levels that encourage exploration off the main route, and the difficulty can spike in later stages, especially when hunting for well-hidden exits. It feels like rediscovering a favorite game, with just enough new twists to keep you on your toes.
