Dreierles is a three-handed, trick-taking Tarot card game that is popular in the German region of central Baden. It is very old and appears to be a south German cousin of Tapp Tarock, the oldest known 54-card Tarot game. Dreierles is played with Cego cards - the only surviving German Tarot cards still produced. German soldiers fighting with Napoleon almost certainly introduced a Spanish modification to Dreierles that produced Baden's national game of Cego. Its relative simplicity makes it a good introduction to games of the central European Tarot family, usually called Tarock games.

Tarot games are card games played with tarot packs designed for card play and which have a permanent trump suit alongside the usual four card suits. The games and packs which English-speakers call by the French name tarot are called tarocchi in the original Italian, Tarock in German and similar words in other languages.
