Mauscheln, also Maus or Vierblatt, is a gambling card game that resembles Tippen, which is commonly played in Germany and the countries of the old Austro-Hungarian Empire.

Tippen, also known as Dreiblatt, Dreikart, Drei Karten, Dreekort, Kleinpréférence or Labet, is an historical German 3-card, plain-trick game which was popular as a gambling game for three or more players. The Danish version of the game was known as Trekort and more elaborate Swedish variants include Knack and Köpknack. It appears to be related to the English game of Three-Card Loo. It was banned as a gambling game in some places.
