Play Super Mario World Expansion Deluxe Online

Super Mario World Expansion Deluxe is a fan-made modification of the original Super Nintendo Entertainment System (SNES) game, released unofficially in the years following the console's lifespan. It builds on the foundation of Nintendo's 1990 platformer, offering a substantial amount of new content for players who had already mastered the base game's secrets.

You control Mario or Luigi, navigating through a greatly expanded version of Dinosaur Land. The main goal remains to rescue Princess Peach, but the journey involves exploring dozens of new levels, many with branching exits that unlock alternate routes on the world map. Signature mechanics include riding Yoshi, who can now perform new actions like a higher flutter jump, and discovering hidden keys that open previously inaccessible ghost houses and fortresses. The pacing is deliberate, with levels often requiring careful observation to find their many secrets, and the difficulty is noticeably higher than the original, especially in the later worlds. It feels like rediscovering a favorite place that has grown larger and more mysterious.
