I occasionally get vaguely intrigued by the sight of a mahjong game in a movie. And occasionally embark on a not-too-thorough search for a computer-powered AI-endowed approximation of the experience to entertain myself without burdening other humans. Which search ends in encountering a number of solitaire applications, but not a four-player version.
Meanwhile, I could play hearts, bridge or even something local such as durak, since the 90s.
