Super Mario Bros
Super Mario Bros is the defining platformer that started it all. You run, jump, and stomp your way through the Mushroom Kingdom to rescue Princess Toadstool from Bowser. The screen only scrolls forward, so every move counts as you time your leaps over bottomless pits, dodge Goombas, and bounce off Koopa Troopa shells. It’s a game of precise momentum and quick reflexes, where grabbing a Super Mushroom or Fire Flower can mean the difference between clearing a tough jump and starting the level over.
This version runs flawlessly directly in your web browser with no downloads or installation required. You get the authentic 8-bit experience exactly as it played in 1985, complete with the original 32 levels across 8 worlds, hidden warp zones, and the classic soundtrack. It’s the perfect way to revisit World 1-1 or finally conquer that brutal jump in World 8.
Controls
- Arrow Keys: Move left, right, crouch, or climb down pipes.
- Z or Space: Jump. Hold it down to jump higher.
- X: Hold to sprint, or press to shoot fireballs when you have the Fire Flower.
- Enter: Start or pause the game.
For mobile devices, use the on-screen virtual buttons to move and jump.
Tips that actually help
- Master the sprint jump: You can’t clear the largest gaps in the later worlds without holding down X to build up running speed before hitting jump.
- Keep the Fire Flower: The Fire Flower isn’t just an attack; it’s a two-hit shield. If you take damage, you revert to Super Mario, giving you a much better chance to survive than reverting all the way to small Mario.
- Watch for hidden 1-Up blocks: Many stages have invisible blocks containing 1-Up mushrooms that only appear when you jump precisely into their hidden space. Try jumping in suspicious empty gaps above solid ground.
- Use the Warp Zones: If you want to beat the game quickly, run across the ceiling in World 1-2 to find pipes that skip straight to Worlds 2, 3, or 4.
