Karnöffel is a trick-taking card game which probably came from the upper-German language area in Europe in the first quarter of the 15th century. It first appeared listed in a municipal ordinance of Nördlingen, Bavaria, in 1426 among the games that could be lawfully played at the annual city fête. This makes the game the oldest identifiable European card game in the history of playing cards with a continuous tradition of play down to the present day.

Knüffeln is a very old trick-taking card game for four players, playing in pairs, that is still played in North Germany. Once considered the national game of Frisia, Knüffeln is a descendant of Karnöffel, the oldest identifiable European card game in the history of playing cards with a continuous tradition of play down to the present day.
