"So they're these cube-shaped toys, right?" Leon starts, setting down his cards (face down) after getting his hand settled for the next round and gesturing with his hands to indicate a roughly two-fist sized shape.

"Each side is a different color, and is divided up into... usually nine squares, in a three-by-three grid. The rows of squares can all rotate freely, so to set up the puzzle, you twist the cube in different directions to scramble the colors." Without really thinking about it, he mimes the motion as he speaks, twisting his hands in opposite directions. "Then you or somebody else tries to unscramble things and get all the sides back to being one solid color each. That make sense?"
