What is "paskahousu"

Paskahousu (, shit pants) is a Finnish card game. The object of the game is to play higher cards than the previously played cards, first to get replacement cards from the stock pile, and, after the stock pile has exhausted, to get rid of one's cards. It is similar to Shithead.

Although the basic play is the same across rule variants, the details of the rules vary tremendously. It is practically impossible to find two identical descriptions of the game in the literature. See the miscellaneous rule variations section below for how the rules vary. One of the most widespread variants is Valepaska, in which the cards are played face down, and players need not announce their plays truthfully.
