Play Super Mario World - The Sixty-four Trials (demo) Online

Super Mario World: The Sixty-four Trials is a 1999 ROM hack for the Super Nintendo Entertainment System, released unofficially by a dedicated fan. It takes the familiar world of the original game and reconfigures it into a gauntlet of focused, self-contained obstacle courses, a common but demanding style of fan creation for the platform.

You control Mario through sixty-four individual screens, each one a compact puzzle of platforms and enemies that must be cleared in a single life. The primary objective is simply to reach the goal in each trial, but the challenge comes from precise jumps, clever use of shell kicks, and finding the one safe path through the chaos. The pacing is relentless, with no checkpoints or power-ups to ease the tension of a difficult sequence. It feels less like an adventure and more like a grueling test of pure platforming skill, where every successful screen brings a sharp, earned satisfaction.
