FullScreenMario is a free HTML5 remake of Nintendo's original Super Mario Bros.
It includes the original 32 levels, a random map generator, a level editor, and over a dozen custom mods.
FullScreenMario was made possible first and foremost by Nintendo, who originally created Mario and has since maintained the series.
It would also not have been possible without the dedicated efforts of the Mario fan community over the past three decades, in particular themushroomkingdom.net.
