I was helping with the estate sale today and came across a King's Court card game. My brother-in-law invented, marketed, and found investors for this game. As I recall it was around 1982.
About a year ago I was talking to an inmate who knew the game very well and used to play it with his wife and another couple. He's now doing time for killing the man he used to play King's Court with for having an affair with his wife.
