What is "polskpas"

Polskpas is a Scandinavian 5-card plain-trick game for four individual players using 24 cards. Eldest hand has the first right to accept or make trumps. As is typical for Schafkopf card games, which are normally point-trick games, the four jacks are known as wenzels and form permanent highest trumps. The German game Kontraspiel is a variant of Polskpas.
