Tarot games are most popular in France, Austria, and Italy but are also played in Switzerland, Germany, Denmark, the Czech Republic, Hungary, and other countries of the former Austro-Hungarian Empire. Specific games vary in detail from place to place but on the whole are more remarkable for their similarities than for their differences.

Most tarot games are played by three or four players, some by five. There are no fixed partnerships, but temporary alliances against the leading player are usually formed from deal to deal.

There are three components to the tarot deck:

In French, Danish, and some Italian games, the full complement of 78 cards is used, but most central European games are played with a 54-card pack lacking the 2s through 7s of each suit.

The concept of trumps had already been imperfectly prefigured in the earlier German game of karnöffel by the attachment of special powers to certain individual cards, but its full realization in the form of a fifth suit was unique to trionfi. This invention added a new dimension to the skill and interest of trick play and proved so popular that it was adopted into the standard 52-card deck by the simple device of randomly choosing one of the four standard suits to play the part of trionfi. Thus arose by the end of the 15th century the French game of triomphe and its English equivalent, triumph, or trump, the immediate ancestor of whist and, ultimately, bridge. With this transference of meaning, the 22 special cards became known in Italian as tarocchi, a word of unknown origin.

The usual aim of tarot games is to win tricks, which vary in value according to the cards they contain. Typically, the fool, trumps I, XX, and XXI, and the four kings are each worth five points, the queens four points, the knights three points, and the jacks two points. The actual scoring is complicated by the fact that points are also awarded for individual tricks, and there is some trade-off between trick points and card points. In most games an additional object is to win the last trick with the lowest trump; in many games additional points are scored for declaring certain card combinations that may be dealt (such as trump sequences); and in central European games players can score extra points by announcing in advance their intention of achieving certain specified feats.

Players must follow suit to the card led if possible and are obliged to play a trump if unable to do so. In all tarot games except French tarot, the suit cards below the jack rank “upside down” (1 down to 10) in the two red suits (hearts, diamonds) or round suits (cups, coins).

There was a resurgence of French tarot during the last half of the 20th century, and its rules are (theoretically) governed by the Fédération Française de Tarot. Austrian tarock has developed a number of increasingly complex games, of which the most advanced is königsrufen (its name meaning “call the king”). Other significant tarot games include ottocento (Bologna), paskievics (Hungarian tarokk), cego (Germany), and the old Italian game of minchiate, played with a pack expanded to 97 cards, which became extinct in the early 20th century. Features derived from tarot games are to be found in many European national card games, such as skat (Germany), preference (Russia), and vira (Sweden), while the game of Bavarian tarock, despite its name, is now played exclusively with standard (German-suited) cards.
