MarioPlex

The number of potential levels that can be made in Nintendo's video game, Super Mario Maker. The number has an approximate value of 10^12431, discovered by MattPatt of The Game Theorists on August 8th 2017. This number is thought to be greater than the number of particles in the observable universe.

I hope my design in Mario Maker doesn't get lost in the vast MarioPlex of levels already in there.
