Calling for Best
A player who has chosen to go alone may discard one card, face down, and call for his partner's best card. The partner must select his "best" card without any consultation.
If a player "assists" and then chooses to go alone, the dealer may consider the face-up card when selecting his "best" card.
Joker
Add one joker to the deck before shuffling the cards. The joker ranks as the highest trump card. If the joker is turned face-up, the proposed trump suit is hearts.
Laps
If a player or partnership exceeds five points, he (they) may carry the extra points into the next game.
Slams
If the losing side scores zero points, the game is worth double.
