It used to be Pinochle, but I haven't played it in so long that I don't know any more.
A card game. lol It is generally played with 4 people and one deck, though can also be played with 3 people and/or with a double deck of pinochle cards. The object is to collect as many of the cards as possible and if you collect them all, it's called "Shooting the Moon" and you automatically win. I remember that the card deck is different from regular playing cards and that when there are four players, two of the players work together as a team against the other two players. I can't remember much of anything else about it. I haven't played it since I divorced my first husband back in 1984ish.
