You've probably heard of Super Mario , one of the few video games that can claim to reflect differences in common sense over generations and decades. Almost everyone on the planet has heard of Mario, the Italian plumber who always wears a jumpsuit. Anyone can now play it for free online on a PC.

You will have to navigate the Mushroom Kingdom as Super Mario. Defeat the deadly mushrooms along the route, and then rescue the princess from Bowser, the game's major antagonist.
