I created these dice for a solitaire dice game I came up with called "The Lone Wanderer".

Originally, I created the game to be played with 3 common six-sided dice (as you will see in the instructions pdf), however, I decided to design some custom dice for it.  the faces should be fairly straight forward.  N=North, E=East, S=South, W=West,D=Diagonal, Skull=Death Die

I printed these with 100% infill, skull face up, and the results were fantastic.
