In a 400th anniversary magazine for the University of Tübingen that year, students from Mainz describe the rules for Quodlibet.

The rules given here are based on those used by two student fraternities from the Austrian region: KÖStV Frankonia Wien from Vienna, founded in 1919, and KÖStV Badenia from Baden bei Wien in Lower Austria, founded in 1928, both of which are members of the Mittelschüler-Kartellverband, the umbrella organisation for all such high school fraternities in Austria.

[9][10] A partie in Quodlibet consists of 12 games which, in some circles are divided into three 'wheels' (Rädern) or rounds, each of four deals (Touren).

The first beer king deals 8 cards to each player (normally 3-3-2 or 3-2-3), picks up his hand, chooses a contract from the first round (see below) and leads to the first trick.

The 1888 Meyers Konversationslexikon describes Quodlibet as "a card game that consists of 13 [sic] different deals that is especially popular in student circles".
