Play Super Mario Bros 3 (PC10) Online

Game Overview

Super Mario Bros 3 (PC10) still holds up as one of the tightest platformers on the NES. The first few levels ease you in, but by world 2, you're already dealing with tricky jumps and enemies that force you to actually learn the mechanics.

The power-ups change how you play—the raccoon tail lets you slow-fall, the frog suit makes water levels bearable, and the hammer bros suit is just fun to mess around with. Each world has its own theme, like the desert with angry sun or the giant world where everything's oversized.

It's not perfect—some levels feel like filler, and the difficulty spikes can be brutal if you're not prepared. But the level design is clever, and finding secrets like warp whistles or hidden coin ships still feels rewarding. Super Mario Bros 3 (PC10) nails that balance of being challenging but fair.
