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.

A trick-taking game is a card or tile-based game in which play of a hand centers on a series of finite rounds or units of play, called tricks, which are each evaluated to determine a winner or taker of that trick. The object of such games then may be closely tied to the number of tricks taken, as in plain-trick games such as contract bridge, whist, and spades, or to the value of the cards contained in taken tricks, as in point-trick games such as pinochle, the tarot family, briscola, and most evasion games like hearts. Trick-and-draw games are trick-taking games in which the players can fill up their hands after each trick. In most variants, players are free to play any card into a trick in the first phase of the game, but must follow suit as soon as the stock is depleted. Trick-avoidance games like reversis or polignac are those in which the aim is to avoid taking some or all tricks.
