Schwimmen or Einunddreißig (regionally also Knack, Schnauz, Wutz, Bull, Hosen 'runter and Hosn obi) is a gambling card game for two to nine players, played with a 32-card Piquet pack, that is popular in Austria and Germany. Although it is also called Einunddreißig (Thirty-one or French: Trente-et-un), this should not be confused with a predecessor of Siebzehn und Vier (Twenty-One), also called Einunddreißig. Schwimmen is German for "swimming" which refers to the last chance that a player gets before they drop out.

Variants or similar games in the United States and Great Britain go under the names of Thirty-One, Blitz and Scat, but are played with a 52-card pack. Schwimmen is also played in tournament form.

The game was included in the list of games prohibited in Austria-Hungary by the Ministry of Justice under the names Trente-un and Feuer – but whilst the former name can also refer to the aforementioned Siebzehn und vier ancestor, the name Feuer clearly refers to this game, because in the most common variation a hand of three Aces (Feuer) has special significance (see below).



Schwimmen is played in clockwise order with a pack of 32 French or Double German or German playing cards (Skat pack). When on lead, each player aims to form a certain combination of cards in his hand by exchanging. The aim of the game is not to have the combination with the lowest point value.

Examples of scoring
Queen of Hearts
Ten of Hearts
Jack of Diamonds
This combination scores
10 + 10 = 20 points, because only the Queen of Hearts and Ten of Hearts belong to the same suit.
Ace of Clubs
King of Clubs
9 of Clubs
7 of Diamonds
7 of Hearts
7 of Spades
This combination scores
30 ½ points (in the case of a draw the higher card hand wins).
Ace of Diamonds
King of Diamonds
10 of Diamonds
This combination scores
31 points


There are two ways in which combinations can be formed. The first is where a player either collects cards of the same suit and adds their point values (c.f. the game of Einundvierzig), whereby:

  • An Ace scores 11 points,
  • the court cards – King, Queen and Jack – each score 10 points and
  • the pip cards – 10, 9, 8 and 7 – score their respective face values.

The highest possible number of points is thus thirty-one (Einunddreißig): a hand consisting of an Ace and 2 courts or an Ace, a court and a Ten of the same suit.

The second option is for a player to collect cards of the same rank, e.g. three 7s, three Queens, etc. (obviously of different suits). This combination always scores 30 ½ points.


In an 'open game' (offenes Spiel) the dealer deals three cards, face down and individually, to each player and then 2 packets of three cards to himself. He looks at the cards from one packet and decides whether or not to play with them. If he is happy to play with the cards from this first packet, he must lay the second packet face up in the middle of the table. If he does not want to play with the first packet, he lays these three cards face up in the middle of the table and must play with the cards in the second packet. The remaining cards are put to one side.

The player left of the dealer begins. He may either swap one card or all three from his hand with the cards in the middle – but not two cards. If he doesn't want to exchange, he may either say "I'll shove" ("Ich schiebe") or close the game by 'knocking', usually by rapping his knuckles on the table. In some areas players may say "I'm closing" ("Ich mache zu.") instead of knocking.

End of the game[edit]

A game may be ended in two ways:

  • If a player knocks or says "I'll close", the others may all exchange or shove one more time and then the game ends.
  • If a player holds 31 points (known variously as "Einunddreißig", "Schnauz", "Knack", "Hosn obi" etc.) or, in the case of the variant known as Feuer (c.f. below), if a player holds 3 Aces in his hand - he lays his cards face up on the table and the game ends there and then. This can happen immediately after dealing.

If the game is played, as is common, over several rounds, the losers are at the end. A loser or losers are the player or players who have the card combinations with the fewest points.


If several rounds are played, each player is symbolically given three 'lives'. These may be indicated by counters such as matches or coins. Players have to give up a 'life' each time they lose, by placing one of the counters in the middle of the table.

If a player loses all three lives, he may continue to play but he is now 'swimming' (schwimmt), hence the name of the game. If he loses again, he 'goes under' (geht er unter) and drops out. So 'swimming' is effectively a fourth life and the player's last chance to avoid dropping out.

In this way, there is a form of tournament in which the individual players drop out one by one and eventually only one player is left, the overall winner. If the game is played for stakes, the winner wins the stakes of the losers (or their lives).

Variants and special rules[edit]

Schwimmen or Einunddreißig are played in many variations which differ in detail from the basic rules above. The rules given here are in no wise binding like the rules of chess, for example – before the start of a session, players should ascertain which rules are being used. The most important variations relate to:

  • Cards: for larger numbers of players the game may be played with a pack of 52 whist cards. In Switzerland, Jass packs of 36 cards are used and play is anti-clockwise.
Ace of Clubs
Ace of Diamonds
Aces of Hearts
Example for the variants of Feuer and Blitz
  • Feuer or Blitz: a hand consisting of 3 cards of the same rank usually scores 30 ½ points. Often a hand of three Aces is counted as the highest combination and is called Feuer ("fire") or Blitz ("lightning"). If a player holds 3 Aces, he reveals his cards and the game ends immediately. In this case all the other players lose a life.
  • Losing: among many players the rule is that at the end of a round all players with 20 points or fewer must pay the one who has the lowest score over 20 points. The winner of a round is never paid, even if he is the only player with a score over 20. This rule not only accelerates the game, but offers additional finesses: if a player has 21 points and cannot significantly improve his hand by exchanging, he has to pay in any case. It is therefore to his advantage to worsen his hand by exchanging so that at least another player loses a life. This tactic is known as 'ripping' (reißen).
  • Shoving (schieben): if all players 'shove' in succession, the three cards in the middle of the table are placed to one side and replaced by three new cards from the stock. The player who started the shoving, then leads.
  • Shoving is not always allowed, reducing a players options to exchanging or knocking.
  • Handeln: players may either add the point value from cards of the same suit or of the same rank (c.f. a bit like the game of Einundvierzig).
  • Closed Game (verdecktes Spiel): the player to the left of the dealer is dealt five cards in packets of 3 + 2. He retains three cards and gives the remaining two, face down, to the player on his left, who does likewise.
