Be the first player to reach 66 card points in a hand. Win 7 game points across multiple hands to win the match.
20 cards: A, 10, K, Q, J in all 4 suits. Point values: A=11, 10=10, K=4, Q=3, J=2. You each get 5 cards. The bottom of the remaining 10 cards is flipped to show the trump suit.
Hold K + Q of the same suit? On your lead turn, declare a Marriage for bonus points: 40 pts for trump suit, 20 pts for any other suit. You must have won at least 1 trick first. You then lead one of those two cards.
If you hold the Jack of trumps, you may exchange it for the face-up trump card at the bottom of the stock — but only on your lead turn, after winning at least 1 trick, while the stock is still open.
Before you lead, you can Close the Stock — declaring you'll reach 66 without drawing more cards. If you succeed, you win normally. If you fail, your opponent wins 2 or 3 game points.
