CardGame
From ThorxWiki
A card game is a method of (temporarily) increasing the happiness of Humans, through the coordinated and regulated movements of small black, red and white pieces of cardboard. This is odd, because on the whole it's not the pieces of cardboard that are unhappy.
Nevertheless, many such games exist, mostly based on the random distribution of cards among players, and the relative worth of the cards involved.
