2s make that suit the trump suit for the trick 7s automatically win the round, but if more than one player plays a 7, the last one played wins Jacks are not suit-sensitive, so if the Jack is the highest card played, even if it’s not following suit or a trump, it wins. If more than one Jack is played and they are the highest cards, the trump or one following suit wins, or failing that, the one with the highest suit (S, H, D, C).
Bitches only get given one card, but they can play it in any trick they like. If you don’t win the trick, or, if you’re in a pair and neither of you win a trick, you are eliminated. If you do or your partner does, you are back as a regular player in the game.
