Lady G grew up in a card=playing household. Her parents' games of choice were all manner of rummy, from plain old gin rummy to progressive. Needless to say, as a result, Lady G feels comfortable with a deck of cards in her hands. These days she plays spades in a virtual world called There. Lionheart spent some of his young adulthood playing bridge, a game with which Lady G has never become acquainted except by reputation.
Card games are available in so-called real life, in which you hold the cards in your hands, and online, sometimes at game sites and sometimes at casino sites. GENESSA can guide you to all of these, but only recommends casinos where free play is available and it is not necessary to gamble (although gambling is surely also available at a casino site).
