Cards

The game uses a standard 32-card French-suited pack usually of the Berlin pattern. Cards rank in the usual ace–ten order and the suit of hearts is always the trump suit, hence the name which means "heart card" or "heart hand". The values in card points are: Ace 11, Ten 10, King 4, Ober 3, Unter 2, remainder 0.

Players

Two to five players may play.^{[lower-alpha 1]} If two play, however, the Sevens, Eights and Nines are removed and each player receives 9 cards; 2 remaining in the skat (Stock, Skat, Blinde, Talon). If three play, all the Sevens are removed along with the ♥8 and ♦8, and each player receives 8 cards;^{[lower-alpha 2]} if four play, only the ♥8 and ♦8 are removed and each player receives 7 cards;^{[lower-alpha 3]} if five play, the full 32 cards are used and each player gets 6 cards. In every case, a skat of 2 cards is placed face down in the middle of the table.

Play

After the cards have been dealt, each player is asked in turn whether he wishes to become the soloist and plays against the others. If he does, he can say "(I'll play)" (ich spiele). Once the soloist is decided, he picks up the skat, adds it to his hand and discards 2 cards which count towards his score at the end. Forehand now leads to the first trick. Suit must be followed; a player unable to follow suit, must trump; only if unable to do either may a player discard. If a trump is led, subsequent players must overtrump if able.^{[lower-alpha 4]}

Scoring and settling

Players agree the stake to be played for at the start of the game. After the last trick has been taken, players tot up their points taken in tricks. If the soloist reaches 66 points (including any points in his two discards), he has won the deal. The score may be settled as follows:

• Soloist wins and receives a single stake from each defender.^[2][3][4][5]
• Soloist wins, the defenders having scored 33 or fewer points, and earns a triple stake from each defender.^[5]
• Soloist loses and pays a single^[5] or double^[2][3][4] stake to each defender as agreed.
• Soloist loses with 33 points or fewer, is schneider and pays four times the stake.^{[4][5][lower-alpha 5]}

Variant

Muhr describes a variant in which the object for the soloist is simply to score more points than the defenders. However, before play the soloist may announce "66", an intention to score at least 66 points, or "Du", an intention to take all tricks. A defender may double with "contra" but only if they had no opportunity to bid. The soloist may redouble with "Ree". A 66 is worth double and a Du triple the game value. Winning or losing Schneider also doubles the game value.^[6]
