The premise of the puzzle is that each cube has a mix of one of four icons on each face. Your goal is to stack these four cubes vertically so that each face that is showing a different face (four faces showing per cube as you can't see the top or bottom face). As I mentioned in yesterday's post, it's much like Sudoku where each line has to have something different.
Apparently this is all based on the Polya Enumeration Theorem. I haven't had to time to actually read this article, but it explains how one create their own with different patterns on the cubes.

I decided what would be more fun than to put my favorite puzzle professor on it. It's the type of puzzle you'd see in the game and thought it a good fit.
I'll post another picture once I attach these onto the cubes themselves.
We also played at least six cups that evening in Mario Kart 8. I am extremely terrible that game.
Let me know if you're interested in learning how to play these games.
