Play Super Mario World - Cruel (demo) Online

Super Mario World came out on the Super Nintendo Entertainment System in 1990, developed and published by Nintendo. It was one of the games that really showed what the new console could do, with its colorful, scrolling levels and the addition of Yoshi. This particular demo, the Cruel version, takes that familiar foundation and twists it into something far more demanding.

You control Mario, or sometimes Luigi, and your goal is still to reach the goalpost at the end of each stage. The core mechanics are the same; you run, jump on enemies, collect power-ups, and uncover secrets in blocks. The pacing, however, is brutally fast, and the level design is deliberately unforgiving. Platforms disintegrate the instant you land on them, enemies spawn in perfect trajectories to hit you, and items often cause more harm than help. It feels like the game is actively working against you, turning every jump into a tense calculation. Playing it is a constant, exhilarating test of reflexes and patience.
