This D36 die has 36 sides, each equally likely to land face up - it's not isohedral (meaning it doesn't have quite as much symmetry as most dice shapes), but the design is based on spacing points as equally as possible on a sphere and then cutting planar slices perpendicular to those directions.

In addition to the numbers 1-36, each face is marked with one of the 36 possible results for rolling two pipped six-sided dice - since there are 36 possibilities, you can use this dice in place of two six-sided dice.

Or, if you'd like to model rolling two six-sided dice in a different way, simply take the square root of your D36 to get the equivalent of taking the maximum result from two D6 rolls. Sounds unbelievable? Here's our explanation.

As if it wasn't already cool enough, this die also glows in the dark.
