This game is very popular in Minnesota, USA, where it is just called Whist. It is extremely similar to a Scandinavian game, often listed in English language card game books under the name Norwegian Whist. The main difference from the European version is that in America a black card indicates that one wants to play "high".There are four players in two fixed partnerships. Partners sit facing each other. The game is played clockwise.Each hand is played either "high" or "low". If it is played "high", the partnership that takes at least 7 of the 13 tricks scores points. If it is played "low", a partnership must take 6 or fewer tricks to avoid losing points. Good graphics and intelligent robots will give you a good game.
