The object of this solitaire game is to build a complete picture gallery of Jacks, Queen and Kings. It's a game for a short break. The computer does obvious moves automatically: you concentrate your efforts in making good decisions instead of searching around for movable cards. In addition, you can compare your efforts with the result of a non-strategy (the computer plays many games doing all legal moves in random order). It is implemented as a Java applet.
