Play Super Mario World - Legend of the Four Switches Online

Super Mario World came out on the Super Nintendo Entertainment System in 1990, developed and published by Nintendo. It was one of the defining platformers for the console, building on the Mario formula with a bigger, more interactive world.

You control Mario, or Luigi, running and jumping through levels to rescue Princess Peach from Bowser. The main goal is to explore the overworld map, find keys in ghost houses, and beat castles to unlock new paths. The signature mechanics involve finding four colored switches that permanently change blocks throughout the entire game, opening up secret exits and alternate routes. The pacing is brisk, with a steady difficulty curve that encourages replaying levels to find every exit. It feels like a constant, playful discovery, even after you think you know every secret.
