This is Poker with a difference - cards are replaced by people. Whether male or female, young or old, everyone is worth a certain value. The game can be played by two opposing players on any train with five seats in a row. Originating in Japan in the late 80's as "Subway Poker" and tightly controlled by crime syndicates, the game has subsequently spread to many major cities around the world.
Ever sat on an Underground train and felt you were being watched?
