About Super Mario Bros Online
Super Mario Bros is the platformer that defined a generation. Originally released in 1985, this classic side-scrolling adventure lets you step into the shoes of Mario — or his brother Luigi — as you run, jump, and stomp your way through the Mushroom Kingdom. The goal is straightforward: survive Bowser's forces, collect coins, and reach the flagpole at the end of every level to rescue Princess Toadstool.
How Super Mario Bros Plays
You start each stage as regular Mario, navigating platforms, avoiding pits, and dodging enemies like Goombas and Koopa Troopas. Scattered throughout the levels are special question-mark bricks. Hitting them from below reveals coins, power-ups, or extra lives. Grabbing a mushroom transforms you into Super Mario, doubling your size and giving you the ability to smash brick blocks overhead. If you take damage while big, you shrink back down instead of losing a life, giving you a crucial second chance.
The game features multiple worlds, each with distinct themes and increasingly tricky layouts. From underground tunnels to underwater stages and castle fortresses filled with lava, every environment demands precise timing and quick reflexes. You can select specific levels using the built-in map select feature, or even experiment with the level editor to create custom challenges.
A Classic That Still Holds Up
Few video games have remained in the public consciousness for decades the way Super Mario Bros has. Interestingly, Mario wasn't always a plumber named Mario. He first appeared in 1981's Donkey Kong as a carpenter called Jumpman. Since then, he has become one of the most recognizable characters in entertainment history.

How to Play Super Mario Bros Online
Start by selecting a world from the map screen or jump straight into World 1-1. Your objective is to move right through each level, avoiding enemies and hazards until you reach the flagpole at the end. Touching the flag completes the stage and advances you to the next area.
Jump into question-mark blocks to release mushrooms, fire flowers, or coins. Collecting a mushroom makes you grow into Super Mario, allowing you to break standard bricks and survive one hit without dying. Keep an eye on the timer at the top of the screen, as running out of time costs a life.
Use the map select option if you want to practice specific stages, or open the level editor to build your own courses. You can toggle sound, switch to full screen, and remap your keys from the options menu before you begin.

- If you are small Mario, avoid unnecessary risks until you find another mushroom to grow back into Super Mario.
- Use the level select feature to practice difficult stages repeatedly without starting from the beginning.
- Watch the countdown timer at the top of the screen so you don't lose a life simply by moving too slowly.
