Tips & Tricks for Super Mario Bros

🏃 Master the Sprint Jump

Many of the larger pits in the later worlds cannot be crossed with a normal jump. You must hold the sprint button to build up max speed before leaping.

Hunt the 1-Ups

Invisible blocks are hidden throughout the game. If you jump in seemingly empty spaces, you might hit a block containing a green 1-Up mushroom for an extra life.

🐢 Use the Shells

When you jump on a Koopa Troopa, it hides in its shell. Kick the shell to send it sliding forward, destroying any Goombas in its path!

Got Questions? (FAQ)

Is this the full original game?

Yes! This is a complete HTML5 recreation of the classic 1985 NES title, featuring all 8 worlds and levels.

Does the warp zone still work?

Absolutely. If you run across the ceiling in World 1-2, you can still find the famous Warp Pipes to skip ahead to later worlds.

Do I need an emulator?

No downloads or external emulators are required. The game engine runs natively directly inside your web browser.
