Grobhäusern, also Grobhaus,[1] is an historical German vying game in which players bet and then compare their 4-card combinations.

[4] Grobhäusern is mentioned as early as 1749 as a "pleasant German game" alongside Rummel, Scherwentzeln and Contra.

Adelung suggested that Scherwenzel is the origin of the designation wenzel for Jacks as highest trumps.

Eldest hand is obliged to bet the minimal wager, then all other players in turn may either call or fold.

In descending order the possible combinations are When there is a tie even after counting card-points, the player who sits earliest in the direction of play wins, starting with eldest hand.

In this case all players who folded in the first round must raise their stakes retroactively and the pot is held in abeyance.

[11] Färbeln, Farbl'n or Einunvierzig is a more complex, Danubian (Austro-Hungarian), variant.
