Rumpel is a card game, that is native to the Danube region from Regensburg to Linz, but is played especially in the region of Hauzenberg in the German county of Passau in Bavaria. Mala describes a version with 8 or 12 contracts from a menu of 29 called Großer Rumpel. It is a descendant of the old Austrian student's game of Quodlibet.

A card game is any game that uses playing cards as the primary device with which the game is played, whether the cards are of a traditional design or specifically created for the game (proprietary). Countless card games exist, including families of related games. A small number of card games played with traditional decks have formally standardized rules with international tournaments being held, but most are folk games whose rules may vary by region, culture, location or from circle to circle.
