Mario Bros World is a one-button runner platformer where Mario runs automatically. Your task? Tap or click to make him jump and navigate through 30 levels full of spikes, mushrooms, and hidden gates. Each stage demands sharp timing and reflexes to collect the green mushroom and reach the castle.

MARIO BROS WORLD: PRECISION TIMING MEETS CLASSIC MARIO FUN

In Mario Bros World, Mario continuously runs forward, bouncing between walls or pipes. You control his jump with mouse clicks or taps—no direct left/right commands. Every level requires careful timing to avoid traps and land on platforms correctly.

Collect the green mushroom in each stage before making your way to the castle; only after securing it does the castle gate open. Miss it—or hit a spike—and you’ll have to restart. There’s no turning around: you rely on rebounds off walls or ceilings to change direction.
