Play Mario Bros [a1] Online

Game Overview

Mario Bros on the Atari 2600 is one of those games that feels way simpler than you remember—but in a good way. You’re just Mario (or Luigi if you’ve got a buddy), jumping between platforms and knocking out enemies by hitting the floor beneath them. Flip a Shellcreeper over, give it a kick, and watch it vanish. Easy, right? Then the ice physics kick in, and suddenly you’re sliding into a Sidestepper like a clumsy plumber on a banana peel.

It’s definitely stripped down from the arcade version—no POW blocks, no fancy animations—but there’s something weirdly satisfying about the bare-bones chaos. Two-player mode turns it into a mix of teamwork and accidental sabotage, especially when you both go for the same enemy and end up colliding mid-jump. Also, fun fact: this was one of the first times Mario wasn’t just rescuing Pauline from Donkey Kong. He’s just… here, punching turtles in a sewer. Classic.

If you’ve got a soft spot for janky old-school charm, this one’s a time capsule worth dusting off.
