Play Super Mario World Laughs Online

Super Mario World Laughs is a 1990 modification of the original Super Mario World, released for the Super Nintendo Entertainment System and developed by Nintendo. It exists as a humorous, fan-made alteration that repurposes the familiar mechanics and level design of one of the platform's foundational titles, offering a different kind of experience within the same classic framework.

You control Mario, or sometimes Luigi, navigating side-scrolling levels filled with platforms, pits, and enemies. The main objective remains to reach the goal post at the end of each stage, but the core experience is transformed by the complete replacement of all sound effects with various samples of laughter. Every jump, coin collection, and enemy defeat triggers a different chuckle, cackle, or guffaw. The pacing and difficulty are identical to the original game, demanding precise jumps and careful exploration, but the constant, absurd audio track creates a persistently silly atmosphere. It feels like playing a very competent platformer while someone is having a fit of giggles just off screen.
