I don’t believe a game of it was ever shown being played–unlike Bajorran Springball, which I just saw for the first time in a DS9 ep. on SpikeTV; that 4-D chess game they play; Stratagema (where you put wired sensors on your fingers and jiggle them around while a holographic display shows you gaining or losing board real estate, a la Go–or possibly Qix); oh, and that crappy addictive Rysian game that induces mind control. But not Parisi (sp?) Squares. All we seem to know about it is that:
a) it’s very dangerous
b) so much so that you aren’t supposed to play it until you’re older
c) it requires you to wear some sort of tight-fitting bodysuit (ISTR seeing Worf and a few other officers going off to play a starbase/other ship’s crew, and they were all geared up)
So what else do we know about the game? (Particularly its spelling.)
