Dobbm or Tappen is a card game played in the Stubai valley in Austria and is one of a family of games derived from the Tarot game of Grosstarock by adapting its rules to a regular, shortened pack of 36 cards. The ranking and point value of the cards in Dobbm is typical of the family and, like its other members, one player always plays as a soloist against all the others. It is highly popular in the Stubai valley among card players of all generations, but is unknown in the surrounding regions.^[1]

The aim of the soloist is to score more than 60 card points (Augen) in tricks, unless he has announced a higher target. The opposing team only needs to score 60 points to win.

There are 4 active players. Five can play, in which case the dealer takes a holiday (er feiert).^[1]

Dobbm was originally played with Salzburg pattern cards until the 1960s, but now it played with a deck of 36 cards of the William Tell or Hungarian pattern, the so-called Tell cards.^[1]

Trick-taking strength

The cards’ trick-taking power broadly corresponds to their card point value. Thus the Sow (Sau) or Deuce (Daus) is the highest-ranking card. Then follow the: Ten > King > Ober > Unter > Nine > Eight > Seven > Six. This ranking is also valid within the trump suit as well as the plain suits. Hearts are permanent trumps.

The first dealer is chosen by lot. The dealer shuffles the cards and the player on the dealer's right cuts. The dealer then deals 2 packets of four cards to each player in clockwise order. The last four cards are placed face down on the table to form the Dobb. The role of dealer does not rotate; instead the last declarer becomes the dealer.^[1]

Play is clockwise and the declarer leads to the first trick. Each player must follow suit if possible (Farbzwang). If a player is unable to follow suit, he must trump (Trumpfzwang, i.e. play a card of the Hearts suit). The winner of the trick leads to the next trick. The defenders keep their tricks in one place.^[1]

After the last trick has been taken the sides count their card points, the declarer remembering to including the dobb. There are 120 card points in toto. If the winning side takes all tricks it is a matsch.

The stake is expressed in terms of the cost of a matsch (worth 60 points) and is typically a multiple of six e.g. 6 or 12 schillings. The winning side claims the amount of money, chips or game points based on the number of card points above 60 that they have scored e.g. if a matsch is worth 12 schillings and the declarer scores 71 points, he receives 3 schillings from each defender.^{[lower-alpha 1]} If both sides score 60 it is a draw (eingestellt). The payments are doubled for a Solo, a Schwacher and each Retour.^[1]

Revoking (failing to follow Farbzwang or Trumpfzwang) is called verleugnen or laungen and is penalised with half the value of the game being played.^[1]

A session of Dobbm often ends with a Mußrunde ("must round"), which is where each player in turn (always being the one to the dealer's left) must be declarer and choose to play either a Dobbm or a Solo. It ends when every player has been a declarer.^[1]

Dobbm most strongly resembles the Austrian game of Brixental Bauerntarock in that it is also played by four players, each player is dealt eight cards, four cards go to the talon and Hearts are the permanent trump suit. It is also related to a special version of Tarock also played in the Stubai valley and known as Droggn.
